The Go / No-Go Dashboard

Before you brush your teeth, glance at this card. If even one indicator is red, the day is over before it has begun. If everything is green, only then start packing the bag.

This dashboard is tuned only for your setup - Advance Epsilon 9 size 26 at the top of the ideal range, pod harness, around 100 hours, flying inland UK ridges. As you cross 200 hours and start flying mountains or coast, the amber band will stretch a little wider. For now, kindly stick to these numbers - they are designed to keep you out of trouble, not to maximise your airtime.

The simple rule Every metric must be GREEN for you to drive to the hill. One AMBER means slow down - go to the hill but do not commit to launch until you see it with your own eyes. One RED and the day is finished, no matter how desperate you are to fly. Decisions made at home over chai are always better than decisions made at the launch in the wind.

The ten indicators

All values come from the morning weather workflow in Section 02. The source of each indicator is shown on the tile.

Why these numbers, for you specifically?

You are flying an Epsilon 9.26 at the top of the ideal weight range (~97 kg all-up). This means your wing penetrates wind better than a lighter pilot's same wing, but it also tips, dives, and reacts a little faster. The numbers above respect this trade-off:

  • Top wind cap of 30 km/h on the ground - your pod harness makes ground-handling at 30+ kg/h harder than with a seat-plate harness, even though the wing itself can handle more.
  • Cloudbase 500 m AGL minimum - below that, your thermalling room on a 130 m ridge becomes very claustrophobic.
  • Thermal cap at 4 m/s - at 100 hours, you should be enjoying lift, not surviving it. Save the 5+ m/s days for after 200 hours.

The decision logic (no exceptions)

Walk through it like an aircraft pilot would, no shortcuts:

  1. Indicators 09 and 10 first - any RED here, day is dead. Go for a hike instead.
  2. Indicators 02 and 03 next - wind aloft and gust factor decide if it is going to be a smooth or violent day. Any RED, stay home.
  3. Indicators 01, 04, 05, 06 - the on-day picture. Any RED, drop it.
  4. Indicators 07, 08 - thermal quality. Two AMBERs here mean a "fly cautiously and land early" day, not a "stay home" day.
  5. If still all GREEN or only 1-2 AMBER on indicators 07-08, drive to the hill. The site itself will give the final verdict.
Common pitfall - the desperate pilot You have not flown for three weeks. The forecast is marginal. Your friends are going. The temptation to push through one amber, then two, then a red, is the single most common reason pilots end up in hospital in the UK. The dashboard does not care about your weekend plans. Trust it.
Section 02

The Morning Weather Workflow

Six steps, in this order, every flying morning. The whole thing takes 15 minutes once you have done it ten times. Skip a step and you will be the pilot who launches into a sea-breeze front because nobody told you it was coming.

Each step uses a different forecast model. Because no model is perfect, the magic is in cross-checking: when three independent sources agree, you can trust the day. When they disagree, the day is uncertain, and uncertainty itself is a reason to be conservative. Kindly do all six steps even on days that look obvious - habits are what save you on the days that look obvious but actually are not.

Workflow philosophy Step 01 tells you "what kind of day". Steps 02–04 tell you "the numbers". Step 05 tells you "where to fly". Step 06 tells you "how confident are the numbers". Do not jump to step 03 first - without the synoptic context, the numbers can mislead you.
Step · The Big Picture · ~ 2 minutes

Synoptic Chart Glance

Where: Met Office surface pressure chart · or any synoptic chart for UK + nearby Atlantic.

What you are looking for:

  • H or L? A high pressure (H) means stable air, often blue thermals or weak thermals, but reliable. A low pressure (L) means unstable air, stronger thermals, but real overdevelopment risk.
  • Isobar spacing. Tightly packed isobars over the UK = strong gradient wind aloft, even if the surface looks calm. Loose isobars = light winds.
  • Fronts. Look for the bumpy lines (warm and cold fronts). If a front is anywhere within 6 hours of crossing your area, that day is finished - the air becomes unpredictable around fronts.
  • Direction of flow. The general air mass direction tells you which face of the hill will work.
Red flags at this step Cold front within 6 hours · isobars tight enough that the wind would need a knife to cut · low centred over the UK with no inversion cap · "ridge of high pressure" is fine, but watch for a trough following.

Flybubble Weather - narrow down the day

Where: weather.flybubble.com

How to use it: Flybubble gives you a 5-day UK overview built specifically for paragliding, using the RASP model in a friendly map. Two overlays, both must be checked:

  1. Wind at 10m (the default) - colour map of forecast surface wind. Read the legend at bottom-left.
  2. Stars (thermals) - switch to this to see thermal strength.

The colour code (memorise this):

  • Dark blue too light to soar - under 8 km/h
  • Light blue → mid-green ideal for paragliders
  • Light green / yellow top end, breezy, getting marginal
  • Yellow → red → dark red blown out

Step through every hour from 10:00 to 18:00 - the colour will change. Mark the window where your area is in the GO band and shows green/yellow stars (thermals).

Decision output of this step A rough flying window (e.g. "Saturday 12:00 to 16:00, Chiltern area, mid-green wind, 3-star thermals"). Do not commit to a site yet - just narrow down the day and the hours.

RASP Stratus Blipspot - drill into your site

Where: rasp.stratus.org.uk · blipspot-maker

How: Enter the lat/lon of your chosen launch (or pick a saved site), select the day, and generate the graph. You will get one image with multiple curves over the day. Read the parameters in this exact order:

Read Parameter What it tells you Your target
1st Surface Wind Wind at the launch · for take-off 12 – 25 km/h
2nd BL Average Wind Wind you feel while thermalling < 30 km/h
3rd BL Top Maximum thermal height (dry) > 1000 m
4th Cu Cloudbase Cloudbase if cumulus form > hill + 800 m
5th W* (updraft) Average thermal strength 1 – 3 m/s
6th OD Potential Risk of sky filling in < 30 %
7th B/S Ratio Thermal vs. shear quality > 5
Easy mistake Surface Wind at 14:00 looking great does not save you if BL Average Wind at 14:00 is 40 km/h - that means your thermals will be pushed downwind faster than your glide, and going upwind to land becomes a problem. Always read both.

Meteo-Parapente - wind at altitude & instability

Where: meteo-parapente.com · click on the UK area, drop a pin near your site.

What to look at, in order:

  1. Wind at altitude maps. The right-side scroller steps in 250 m increments. Step from 0 m up to 3000 m. The colour scale is paragliding-tuned: green = safe, yellow = marginal, red = danger. If the wind goes from green at 1000 m to red at 2000 m, you have a wind gradient - turbulence guaranteed.
  2. The windgram. Shows wind arrows over time on a vertical altitude scale. The yellow shading is instability - the darker, the more thermic. Watch for thermals breaking through cleanly, or for arrows that change direction with altitude (= shear).
  3. The sounding. Black curve = actual temperature, blue = dewpoint. When the two meet, you get cloud. The slope of the black line tells you stability - vertical or right-leaning = stable; left-leaning = unstable.
Decision output Confirm or reject your earlier wind-aloft number from RASP. If RASP says 25 km/h at 1500 m and Meteo-Parapente shows 45 km/h at the same altitude, do not fly - the models disagree and one of them is dangerously wrong, but you do not know which.

Match the wind to the hill

You now know the wind direction at the surface and aloft, the strength, the cloudbase, and the thermal quality. Time to pick a hill. The simple rule is: the hill must face the wind. The wind comes from the direction the hill is named for (a "northerly site" works in north winds).

For your area (Aylesbury), the four club sites cover most directions between them, but with restrictions:

  • Dunstable Downs - main paragliding hill of the area, but inside Luton CTR. You must have the DHPC airspace briefing, helmet sticker, and a calibrated altimeter. Best in southwest. Visibility minimum 5 km is a hard legal requirement.
  • Sharpenhoe Clappers - east-northeast site, open from 045° to 090° but never south of east. The air gets nasty and turbulent if the wind veers to the south of east, regardless of speed.
  • Chinnor - northwest, 300°–340°, best around 320°. A one-flight site (top-landing only for experts) so plan a ground retrieve. Limited launch area through trees.
  • Ivinghoe Beacon - public-access hill, west-southwest mainly used by model fliers. Useful for ground handling practice on light days.
Decision output A primary site, a backup site (in case wind direction veers), and the legal/airspace check done - for Dunstable, that means CRSA ceiling at 1500 ft AMSL and the airspace sticker on the helmet.

Step · Confidence Check · ~ 1 minute

Cross-check the three forecasts

You have surface wind from RASP, wind aloft from Meteo-Parapente, and a national overview from Flybubble. Now ask: do they agree?

  • All three roughly agree (within 5 km/h on wind, within 200 m on cloudbase) → high confidence. Proceed to drive.
  • One outlier, two agree → moderate confidence. Trust the two, but treat the day with respect. Land before the forecast worsens.
  • All three disagree significantly → low confidence. The atmosphere is in a state the models cannot pin down. Stay home, or at minimum wait for the next model run (RASP refreshes mid-morning) before deciding.
The 11:00 sanity check Always re-run RASP and Meteo-Parapente at 11:00 (most models update by then). If the new forecast is significantly different from your 08:00 plan, treat that as a warning - the day is more changeable than expected, and your plan probably needs to shrink, not grow.

End of workflow. You should now have written down: a day, a window of hours, a primary site, a backup site, and four numbers (surface wind, wind aloft, cloudbase, thermal strength). That is your morning weather report. Take it to the hill.

Site Selection - Picking Today's Hill

The wind has already chosen the hill for you. Your job is only to recognise which one. Each site has its sweet-spot direction, its hazards, and its rules. Memorise the home four; respect every new site like a new boss.

This section has four parts. First, your four home sites in detail. Second, a wider net of sites within roughly two hours' drive when the home sites do not work. Third, a comparison of site types - flat, inland ridge, mountain, coast - because the same wind speed means very different things at different sites. And fourth, a short workflow for assessing any new hill using PeakVisor and FreeMapTools.

Note
Paragliding rare here
Mainly a model-aircraft slope-soaring spot, not a club paragliding site. But the open chalk grassland and steady wind make it the best ground-handling venue in the area on light days when nothing else is flyable. Use it to keep your wing-on-the-ground skills sharp during winter - those skills directly translate to better launches at the proper sites.

Casting wider - sites within ~ 2 hours' drive

When the four home sites are out of direction, weather window, or club limit (e.g. Dunstable closed for the day, you want to fly without the airspace stress), here is your secondary net. Each of these has its own club, its own rules, and its own briefing - kindly do the homework before turning up.

Always join the local club first UK paragliding sites are member-only at the BHPA club level. Drop a polite email to the local club secretary one week before, ask about a visiting day, share your BHPA card and rating, and many clubs will welcome you for a small day fee. This is non-negotiable - the airspace agreements that allow these sites to exist depend on members-only enforcement.

Site types - same wind, different worlds

A 25 km/h southwesterly is a perfect Dunstable day, a mediocre Welsh ridge day, a marginal mountain day, and possibly a no-go coastal day. Each terrain type behaves differently. Here is what changes:

Flat / Winch sites

Towed launch from level ground

  • Lift source: thermals only, no ridge lift
  • Wind tolerance: works light to moderate (5 – 25 km/h), but no upper margin from ridge boost
  • Risk profile: winch failures, low-tow stalls, tow-line backing
  • Best in: warm summer afternoons with good thermal index
  • UK example: Sutton Bank, Green Dragons winch field

Inland ridge your home turf

Single ridge facing the wind

  • Lift source: ridge lift from wind hitting the slope, plus thermals
  • Wind tolerance: needs minimum to soar (10 – 12 km/h), capped at hill type (~ 30 km/h for paragliders)
  • Risk profile: blow-back over the ridge, lee rotor on the back side, gradient turbulence
  • Best in: wind directly perpendicular to ridge, gentle gradient
  • UK example: all four of your home sites; South Downs sites
rotor

Mountain

Multi-ridge complex terrain

  • Lift source: thermal triggers, valley winds, anabatic / katabatic flow, occasional wave
  • Wind tolerance: tighter than ridge - over 25 km/h on the launch usually means dangerous lee zones nearby
  • Risk profile: rotor on every lee face, foehn (warm dry strong wind), valley wind reversal at sunset, high cloudbase that suddenly drops
  • Best in: stable mornings with light gradient, classic Alpine "valley breeze" days
  • For 100-hour pilot: hire a local guide for first 3-4 mountain days. UK examples: Brecon Beacons, Lake District

Coastal cliff

Sea-breeze driven lift

  • Lift source: sea-breeze ridge lift, very smooth and consistent
  • Wind tolerance: works in lighter onshore wind than inland (8 km/h is enough sometimes), capped sooner because the breeze accelerates as the day warms
  • Risk profile: sea-breeze front pushing inland cuts off retreat; coastal fog rolling in within minutes; landing on beach with rocks/tide
  • Best in: sunny days, light gradient, onshore component
  • UK example: Beachy Head, Rhossili, north Devon coast

Assessing a new site - the 6-step workflow

One day you will travel for a holiday and want to fly somewhere new. Or your mate will rave about a fresh site. Before you launch from anywhere unfamiliar, run this short workflow - it has saved many pilots from a stupid first flight at a site they did not understand.

Step 1 - Get the coordinates

Find the launch lat/lon from the local club's site guide. Note three numbers: launch elevation, bottom-landing elevation, top-to-bottom height.

Step 2 - FreeMapTools elevation

freemaptools.com · click the launch point, get the exact elevation. Then click 5-6 points around the area to map a glide cone - useful for emergency landing planning.

Step 3 - PeakVisor 3D panorama

peakvisor.com · enter the coordinates, rotate the 3D view. Look for: which faces are wind-facing, where the lee bowls are, where the ridge connects to other ridges, where the valley sucks the wind. Spend five minutes here, not five seconds.

Step 4 - Read the club site guide

Every BHPA club publishes detailed guides. Read it twice. Specifically note: rating required, wind direction limits, hazards listed (powerlines, fences, gliders, sheep), top-landing rules, retrieve options.

Step 5 - Talk to a local pilot

Five minutes' chat at the launch with someone who flies there weekly will tell you more than any guide. Ask: "Where do you not go on a day like this?" - that question reveals the unwritten knowledge.

Step 6 - First-flight conservatism

Your first flight at any new site: launch only when conditions are mid-band (not edges), keep ridge altitude high, do not commit to thermalling away from the bowl, plan an early bottom-landing. Treat the first flight as reconnaissance, not performance.

Habit-builder for the new pilot Even on familiar home sites, run the workflow occasionally - it keeps your eye sharp for things you have stopped noticing. The pilot who treats Dunstable like an unfamiliar site sees hazards the regulars no longer see.

End of Part A · Decision Phase. The next part of the runbook covers what happens once you arrive at the hill - site reading, daily inspection, pre-flight checks, the launch decision tree, and the first hour at the launch. Until then, kindly trust the dashboard, walk the workflow, and pick the right hill.

At the Hill · Pre-Launch Phase
Section 04

Site Arrival & Conditions Reading

Park the car, walk to the launch, and then do nothing for fifteen minutes. The hill speaks to those who listen - windsocks, grass, trees, birds, even cloud shadows are giving you data the forecast could not. Skip this and you will launch into a story you do not yet know.

Your morning forecast was a hypothesis. The site itself is the evidence. Most marginal accidents in the UK happen because the pilot drove for two hours, opened the car door, saw a few wings in the sky, and rushed to launch in twelve minutes flat - without ever reading the actual conditions in front of them. Kindly resist that itself. Sit on a rock, drink some water, and watch.

The 15-minute rule From the moment you reach the launch to the moment your wing comes out of the bag, allow at minimum 15 minutes of pure observation. If a friend is rushing you, let them go first - never let someone else's schedule dictate your safety.

Reading the wind without instruments

Your eyes and ears are better than most anemometers, because they sample everywhere, not just one point. Walk along the launch ridge and read these six signals in this order:

SURFACE WIND ~ 245° ① Windsock Steady at 30°-45° below horizontal = ~ 18-25 km/h. Swinging = gusty. ② Grass Lying flat = strong & steady. Pulsing in waves = thermal cycles. ③ Tree tops Bending while grass calm = wind gradient. Hold launch. ④ Birds soaring (no flap) = reliable lift on the ridge ⑤ Cloud shadow Tracks across ground = wind aloft direction (often ≠ surface wind) ⑥ Birds flapping hard going upwind = strong wind aloft SIX FREE INDICATORS · NO INSTRUMENTS NEEDED
Fig. 09 · The hill itself is your most accurate anemometer - read it before you trust any device

Reading the wind with instruments

Once your eyes have given you a baseline, take measurements. Cross-checking instrument readings against what you have already seen prevents two common errors: trusting a device that is malfunctioning, and ignoring a quiet anomaly the instruments cannot capture.

Anemometer

Walk along the launch holding it at chest height for 60 seconds. Note minimum, average, and gust. Gust factor = max ÷ avg. Above 1.4 means turbulent air. Repeat at three points along the ridge - the variation tells you about thermal cycling.

Phone app · Skywatch / Windy

Compare nearest weather station report to what your anemometer says and what the windsock shows. Three-way agreement is the goal. If the app says 12 km/h but your anemometer says 25 km/h, trust your own kit - apps lag the actual conditions by 30-60 minutes.

Webcam check

If the site has a webcam (Dunstable does), pull it up on the phone - useful for cross-checking the windsock against what the camera shows. Also useful before driving to confirm conditions match the morning forecast.


Watch the other pilots - they are your free experiment

If wings are already in the air, congratulations - you have a live experiment running. Watch for two minutes before deciding anything yourself:

Good signs

  • Pilots beating the ridge calmly, gaining altitude steadily
  • Wings staying overhead, no constant pumping of brakes
  • Smooth top-landings happening on the launch field
  • Pilots chatting on the radio, not shouting
  • Several pilots in the air, none looking stressed

Warning signs

  • Wings being pumped constantly, asymmetric collapses visible
  • Pilots getting flushed back over the ridge or sinking out fast
  • Top-landings going wrong, pilots dragged or aborted
  • Empty sky on a forecast-good day - the regulars know something you do not
  • Anyone shouting on the radio about anything
The empty-sky warning On a forecast-perfect day, if you arrive and nobody is flying despite cars in the car park - go and ask why. The local pilots have probably read something subtle (a building gradient, an inversion lifting, a sea-breeze front coming) that your forecast missed. Trust their nose.

Walk the launch · check the landing

Walking the launch - find the hazards

  • Underfoot: sheep droppings (slippery), rabbit holes, rocks, fence posts, uncleared dog mess
  • Behind you: trees that will catch your wing if you blow back, fences, parked cars, other pilots laying out
  • To the sides: rotor sources (lone trees, buildings, terrain step-downs)
  • Above: overhead wires, tow lines, model-aircraft activity, birds of prey defending nests in spring
  • Layout: identify the patch where you will spread the wing - clean, into wind, with at least 10 m clear behind

Checking the landing zone - never assume

  • Wind direction at LZ: may differ from launch by 30-60° due to valley channelling. Walk down or use binoculars to see the LZ windsock if visible.
  • Surface: any livestock today? Crop changes since last visit? Mowing in progress?
  • Hazards: new fences, freshly dug ditches, parked tractors, electric fences (the worst - invisible at altitude)
  • Backup LZ: identify a second field within glide if main LZ becomes unusable
  • Approach: mentally walk through the figure-of-eight or final approach pattern - into wind, with no obstacles in the last 100 m

The forecast vs reality check

Before unpacking the wing, do this final reconciliation. Pull out the report card you filled in this morning (Section 01) and update it with the live numbers. Three patterns to recognise:

Pattern What it looks like What to do
CONFIRM Live conditions match forecast within 10-15%. Wind direction within 20°. Proceed with the morning plan. Confidence is high.
DRIFT Wind 5-10 km/h stronger than forecast, OR direction off by 30-45°, OR cloudbase 200-300 m lower. Reassess - fly only the most stable parts of the day, plan a shorter flight, land before the discrepancy widens.
DEPARTURE Live conditions clearly outside what the forecast predicted - wind doubled, sudden shift, low cloud rolling in early. Stay on the ground. The atmosphere is doing something the models did not catch - that uncertainty itself is the danger. Pack up, do ground handling instead.
Habit-builder Whatever the verdict, write the live numbers in your flight log next to the morning forecast - over time, you will start to see which forecast model is most reliable for your area. After 50 flights, you will know whether RASP or Meteo-Parapente tells the truer story for the Chilterns specifically.
Section 05

Daily Inspection & Pre-Flight Checks

Two checks, very different in spirit. The Daily Inspection is slow, methodical, done once with your full attention. The Pre-Flight is fast, verbal, and done immediately before every single launch - including the second flight of the day. Skipping either one is how pilots end up under their own twisted wing.

The Epsilon 9 is a forgiving wing, but it is also a 47-celled aerofoil with roughly 350 metres of internal Dyneema - there are a thousand small things that can go wrong, and only a hundred of them will be obvious during the launch run. Most equipment failures could have been caught on the ground if the pilot had taken three extra minutes. Kindly do the needful.

The "I checked it last weekend" trap A wing that was perfect last Sunday can have a knotted line, a chewed brake handle, or a stuck-shut reserve pin by next Saturday - mice in the boot of the car, a quick repack done in the dark, the bag squashed under bigger luggage. The DI is not redundant. Every flying day, kindly do it fresh.

The Daily Inspection - six zones

Spread the wing on the ground first, in the wind, with risers attached to harness. This lets you DI the glider and harness as one connected system rather than two separate piles of fabric.

DAILY INSPECTION · WING LAID OUT FOR REVERSE LAUNCH HARNESS RES 1 2 2 3 4 5 6 ① Leading edge · open all cells ② Wingtips no rips, stabilo lines free ③ Lines walk left to right, no twists, no knots, no snags on grass ④ Risers · A B C D + Brake colours match · maillons tight · brake clove-hitch tied ⑤ Brake handles snap fits free, lines run clean ⑥ Reserve handle visible · clear · pin set
Fig. 10 · The DI tour - six numbered zones, walk them in order, never skip one
1

Leading edge

Walk the entire span. Every cell mouth open and clear of grass, leaves, or twigs. No tears in the top surface. Look for line-attachment points - tape intact, no fraying.

~ 60 seconds · entire span
2

Wingtips & trailing edge

Both wingtips intact, stabilo lines free, no rips along the trailing edge. Check the brake-line attachment points at the trailing edge - these take constant flex and fatigue first.

~ 30 seconds · both tips
3

Lines

Walk from wing to risers, separating each line gently with your fingers. No twists, no knots, no tangles around grass tussocks. A snagged line will pull the wing sideways at launch - bad outcome.

~ 90 seconds · A then B then C then D
4

Risers & maillons

Risers in correct colour order (A red front, then B, C, D back). All maillons tight by hand. No twists between risers. Brake-line clove-hitch knots tied tight, brake handles attached the right way round.

~ 30 seconds · both sides
5

Harness, helmet, instruments

All harness buckles working - chest, leg straps, shoulder. Speedbar route clear. Helmet chin strap intact, airspace sticker present (if Dunstable). Vario powered and showing GPS lock. Radio on, channel correct, PTT clicks.

~ 60 seconds · sit in harness, do hangcheck
6

Reserve parachute

Reserve handle visible, accessible, free of obstruction. Pin or velcro closure intact. Reserve still in date for repack (annual). Bridle attachment to risers/harness intact and not twisted.

~ 45 seconds · the most important 45 seconds

The Pre-Flight check - done before every launch

The DI is done once, when you arrive. The pre-flight is done every single time you stand up to launch - including the second flight of the day, the bottom-to-top relaunch, the practice ground-handling session that turns into a real launch. The acronym used in UK BHPA training is AFTERS. Touch each item and say it out loud - the verbal confirmation matters.

A
Airspace

Clear above & around

Look up. Look behind. No incoming pilots, no model aircraft, no birds of prey on the ridge. At Dunstable, additionally confirm visibility > 5 km legal minimum and altimeter calibrated to local QNH.

F
Flight controls

Brakes free, lines clean

Brake handles in hand, give a gentle tug - both brakes respond, no snags, no dragging on grass. Eyes glance up the lines, all clear from riser to wing. No bramble, no twigs, no other pilot's lines crossed over yours.

T
Turn

Pre-decided direction

Which way will you turn after launch? Left or right? Decide now, on the ground, with reasons (the lift is to the left of launch, the spine of the ridge runs right, the airspace is to the south). Saying it out loud commits the brain.

E
Equipment

All buckles, all secured

Hands tap each in turn: chest strap clipped, leg straps clipped, shoulder straps clipped, helmet chin strap clipped, gloves on. The dreaded "leg-strap-not-clipped" accident kills more pilots than any equipment failure - never skip this tap-check.

R
Reserve

Handle accessible & free

Right hand drops to where the reserve handle lives, touches it, comes back. Confirms three things in one motion: it is there, it is free, you know exactly where to find it under stress.

S
Sky

Stable for the next 5 min

Last look upwind - any incoming clouds, gust front, dust devil, or rain shower in the next five minutes? If yes, kindly wait it out. The wing is laid out - that is the easy part. The hard part is choosing not to launch when everything else is ready.

Why touch & say it out loud? Verbalising forces the brain to actually process each item rather than skim past it. After a hundred launches, the AFTERS becomes a 15-second mantra muttered under your breath - that mantra has saved more pilots than any technical skill.

The hangcheck

Before AFTERS, while still at the back of the launch area, sit in your harness with the wing weighted (someone else holds the riser, or hook to a fence). Lift your feet - does everything sit comfortably? Are the brake-line lengths correct (handles at jaw level, not shoulder)? Does the seat-board sit flat under you? Reserve handle still where you can grab it?

This hangcheck takes 20 seconds and is the single best way to catch a riser-twist or brake-line problem before you are airborne. Many pilots skip it after the DI because "I would have noticed" - but you would not have noticed a twisted A-riser caught in the bottom of the speedbar pulley until you tried to push the bar.

The "second-flight syndrome" Top-landed and want to launch again? You skipped the AFTERS, did you not? The second flight has the same accident rate as the first, despite being thirty seconds after. The wing repacked itself in the wind, the reserve handle moved when you sat down, your chest strap is suddenly half-undone. Re-do AFTERS. Always.
Section 06

The 60-Second Flight Plan

Before you clip in, stand on the launch and say the plan out loud. One minute, eight elements, no improvisation. The pilots who fly long careers do this every single launch. The pilots who get hurt are the ones who launched first and "decided in the air".

A flight plan is not a paper document - it is a 60-second verbal contract you make with yourself. It anchors the brain to specific decisions made on the ground, when oxygen and adrenaline are both at normal levels. Once airborne, your decision-making degrades - every plan made in the air is worse than a plan made before launch.

Why verbal? Saying the plan aloud (even muttered to yourself) engages the language part of the brain, which is the same part that holds the plan in working memory once airborne. A silent mental plan often vanishes the moment your feet leave the ground. A spoken plan stays.

The eight elements

Walk through these eight elements every time, in this order. The whole script is roughly 60 seconds when you have the rhythm. The diagram below shows what each element looks like for a typical SW day at Dunstable - the pattern transfers to any site.

FLIGHT PLAN · DUNSTABLE · SW WIND 18 km/h · CB 1100m AGL CRSA CEILING · 1500 ft AMSL SOFT CEILING 1300 ft · stay 200ft below LEE ROTOR · NO-GO WIND 240° · 18 km/h CLIMB to 1300 ft BOTTOM LZ BACKUP LZ 1 2 3 4 5 6 7 8 KEY lift band (wind-facing) lee rotor (no-go) restricted airspace 8 · weather check
Fig. 11 · Eight elements of the flight plan, drawn for one specific day at one specific hill
1

Launch direction

"I will face 240°, into the wind, with the ridge spine on my right." Naming the heading and the spine orientation prevents the classic blunder of laying out 30° off-axis.

2

Initial track after launch

"Once airborne and clear of the slope, I will turn left along the ridge towards the main bowl." Pre-decided turn direction stops the moment of paralysis when the wing first lifts you.

3

First lift target

"I expect lift in the main bowl, 400 m left of launch, where the slope steepens." Even if it is wrong, having a hypothesis means you can confirm or reject quickly rather than wandering.

4

No-go zones

"I will not fly behind the ridge spine, not below 50 m AGL away from the LZ, and not east of the masts (CRSA boundary)." Specific bans, not vague concerns.

5

Bail-out plan

"If I do not contact lift within 5 minutes, I will fly out front, do a figure-of-eight, and land in the bottom field facing 240°." Knowing the bail-out lets you commit to staying up without panicking.

6

Bottom landing

"Main LZ is the bottom field, into wind 240°, approach pattern figure-of-eight from the south. No livestock today, fence on the west side." Mental walkthrough completed.

7

Backup landing

"If main LZ becomes unusable (livestock arrives, wind shifts), the backup is the field 200 m south-east, into wind, no obstacles." Always two LZs in the plan.

8

Time / weather limit

"I will land by 16:00 regardless, or sooner if cloudbase drops below 800 m AGL or wind exceeds 25 km/h on the launch windsock." Hard limits, not negotiable in the air.


The 60-second verbal template

Memorise this script and adapt the bracketed sections each flight. Mutter it under your breath while you are clipping in - by the time the karabiners click, the plan is in your working memory.

Today's plan · "Launch facing [heading], with the ridge on my [left/right].
Once airborne, I turn [left/right] towards [landmark].
First lift expected at [location], approximately [distance] from launch.
I will not go [no-go zone], and I will stay below [ceiling] ft AMSL.
If no lift in [X] minutes, bail to [main LZ], approach [pattern].
Backup LZ is [backup field], [direction] of main.
Hard limit: land by [time] or sooner if [trigger]."
The "no plan" symptom If you cannot say the plan in under 90 seconds, you do not have one. Stop. Sit down. Re-read the conditions. Re-walk the launch. The flight you cannot describe is the flight you should not take.

When the plan changes mid-flight

Plans often need amending. The conditions change, you find lift in an unexpected place, the cloud builds faster than forecast. The rule is simple - when amending, do it explicitly:

  • Out loud, on the radio if needed: "I am changing plan - going to climb to ceiling here instead of going to the bowl."
  • Conservatively: any in-flight change should make the plan safer, not more ambitious. "I am going to land early" is a fine amendment. "I am going to push for the next ridge" is a dangerous one.
  • With a new bail-out: if you change the plan, you need a new bail-out for the new plan. No bail-out = no change.
Section 07

Launch Techniques · Decision Tree

Wing up, check, abort or commit. The launch itself takes seconds, but the technique you chose was decided minutes earlier - by the wind on the windsock. Pick wrong and even a perfect run becomes a dragged-back disaster. Pick right and even a clumsy run gets you into the air.

Three techniques cover almost every UK day: forward, reverse, and the strong-wind variants (cobra, snake, or anchored). At your experience level, the first two are your daily bread; the third is for graduating into and best learnt under instruction. The decision is made by the windsock - not by personal preference, not by what the pilot next to you is doing.

The decision tree

LAUNCH TECHNIQUE · DECIDED BY THE WINDSOCK Wind on launch? read windsock + anemometer < 8 km/h 8 – 18 km/h 18 – 28 km/h > 28 km/h FORWARD alpine launch back to wind run hard REVERSE light wind variant A-risers, light pull, brisk turn, run REVERSE YOUR SWEET SPOT A-risers, hold, check, turn, fly STRONG WIND cobra / snake / abort requires instruction at your hours: pack up cycle in? wait launch on a thermal pulse brakes light, run wing wants to come up brakes balance wing step back if it overshoots ABORT IF · wing not over head · asymmetric · twisted · cravat A bad launch always becomes a worse flight · stop early, reset, try again
Fig. 12 · Wind speed picks the technique · the wing-up check picks "go or abort"

The three techniques · in detail

Technique 01

Forward (Alpine)

Use when: wind on the launch is under 8 km/h and the slope is steep enough that gravity will help. Usually a calm summer morning at Chinnor or a flop-day at Dunstable. Avoid when: any cross-wind component, gusty conditions, or shallow slope.

FORWARD LAUNCH · FOUR STAGES 1 · Layout facing downhill, As in hands 2 · Run + wing rises push As, run hard, lean forward 3 · Check glance up: clean? abort if not 4 · Fly keep running till feet leave
Fig. 13 · Forward launch · layout, run, check, fly
  • Setup: wing in shallow horseshoe behind you, A risers in your hands forward, brakes hooked over thumbs, body facing downhill.
  • Execute: push the As gently up and forward, simultaneously start running hard. Lean into the run. Do not look back.
  • Check: at the moment you feel the wing settle overhead (a slight tug on the harness), glance up - wing clean, symmetric, no twists? Yes → keep running. No → abort, drop the As.
  • Common error: stopping the run when the wing comes up. Stopping causes the wing to surge forward and collapse. Keep running until the wing lifts you.
Technique 02 · Sweet spot

Reverse

Use when: wind is between 8 and 28 km/h on the launch - which covers about 80% of UK flying days. Why: facing the wing lets you see and control the inflation, abort instantly if something is wrong, and only commit to the launch when the wing is genuinely overhead and stable.

REVERSE LAUNCH · FIVE STAGES 1 · Setup facing wing, As in cross-hand 2 · A's pull · wing rises step back as it inflates 3 · Check + balance brakes balance, glance up, abort or commit 4 · Turn pivot under wing, face downhill 5 · Run + fly a few steps, feet up, in seat
Fig. 14 · Reverse launch · setup, inflate, check, turn, fly

The five stages

  1. Setup: wing in horseshoe upwind, you facing the wing. As risers crossed in your hands (right A in left hand, left A in right hand - or your instructor's chosen method).
  2. Inflate: firm pull on As, step back to keep tension as the wing rises. The wing must come up through you, not in front of you.
  3. Check & balance: wing overhead, eyes up - clean? symmetric? Apply gentle brakes to balance. This is the abort window.
  4. Turn: pivot under the wing (clockwise or anti-clockwise depending on which hand was on which riser) so you are now facing downhill.
  5. Run: three to five strong steps downhill, feet leave the ground, in the seat, fly.

Common errors at your stage

  • Pulling As too hard - wing overshoots forward, dives, you cannot catch it. Light, smooth pull.
  • Not stepping back - wing collapses on rise. Match the wing's rise with your step-back.
  • Looking down during the turn - you cannot see if the wing collapsed. Keep eyes up through the turn.
  • Hesitating after the turn - wing surges forward without steady tension. Once you turn, run immediately.
  • Pod harness twist - pod harnesses are unforgiving on a sloppy turn. Practice on flat ground until the turn is one fluid motion.
Technique 03

Strong-wind variants

Cobra, snake, and anchored launches are advanced techniques for wind above 28 km/h. They involve bringing the wing up sideways, walking under it, and only turning into the launch position when fully controlled. At 100 hours and on a pod harness, the honest advice is: do not attempt these unsupervised. A miscued cobra in 30 km/h drags you across the launch - the consequences include broken bones and lost reserves.

If the windsock says strong wind:

  • Default action: wait. Most strong-wind cycles in the UK pass within 30 minutes. If they do not, pack up and try a different day.
  • Practice opportunity: ground-handling on the flat (Ivinghoe Beacon, or the bottom field of any site) is the right place to learn cobra technique. Build it incrementally over 50+ ground-handling sessions before bringing it to a real launch.
  • Coaching pathway: book a strong-wind coaching day with a BHPA Senior Pilot or club coach before your first real cobra launch on a hill. Cost of one coaching session is far less than the cost of one bad strong-wind launch.
  • The Pod harness honesty: pod harnesses make strong-wind launches significantly harder than seat-plate harnesses, because the leg-in step has to happen after launch when the wing is already loaded. Many pilots switch to a string-bag or seat-plate for strong-wind days specifically.

The abort decision · the most important skill in launching

The hands-down most important launch skill is the willingness to abort. A bad inflation that you committed to becomes a tangled mess hanging in trees. The same bad inflation that you aborted becomes a 30-second reset and a perfect launch on attempt two.

Abort triggers - non-negotiable

  • Wing not symmetric overhead after inflation - even slight asymmetry will get worse, not better
  • Twisted lines visible from the ground - anywhere, even one twist
  • Cravat (wingtip pulled into lines) - guaranteed deep stall on launch
  • Brake snagged on grass, fence, your own equipment
  • Cross-wind suddenly picks up just as wing rises - mid-launch direction shift
  • Anyone calls "stop!" from the ground - instructor, mate, randomer; treat the call as authoritative until proven otherwise

How to abort cleanly

  • Reverse: pull both brakes firmly to the hips - wing collapses behind you. Step away from the wing, do not walk into the lines.
  • Forward: drop the As, brake hard, lean back into the wing as it falls. Do not run any further.
  • Once down, do not rush to relaunch. Walk through the lines. Lay out fresh. Re-do the AFTERS. Time spent resetting is time saved on a flight that did not get out of control.
  • If aborted three times in a row, something is genuinely wrong - wind cycle, equipment, or your own state. Pack up for the day. Tomorrow's a new day, and the regulars will not think any less of you for the call.
The pilot's quiet skill Watch the experienced pilots: they abort more often than the newcomers, not less. The 1000-hour pilot who walks away from a marginal launch and resets is showing you the single most useful habit in the sport. Imitate this itself.

End of Part B · Pre-Launch Phase. Once your feet leave the ground, Part C takes over - active piloting, thermalling, ridge soaring, descent techniques, danger recognition, and the landing approach itself. Until then, kindly trust the windsock, run the AFTERS, and abort early.

In the Air · In-Flight & Reference
Section 08

Active Piloting Basics

Once your feet leave the ground, you are not a passenger - you are the second half of a two-piece system. The wing reads the air, you read the wing, and your inputs keep the whole thing pressurised, overhead, and pointing where you want to go.

Active piloting is the difference between flying a wing and being flown by a wing. The Epsilon 9 is forgiving enough that it will mostly fly itself in calm air - but the moment you hit a thermal edge, a gust front, or a wind gradient, passive flying becomes asymmetric collapses, surges, and the kind of stories you do not want to tell.

The mantra · pressure on the brakes, pressure on the harness Two things should always be talking to you. The pressure of the brakes against your hands tells you the wing's angle of attack and how much air it is finding. The pressure of the harness against your back/legs tells you the wing's loading - high pressure means strong lift or a surge, low pressure means a collapse coming. If both pressures suddenly drop, prepare to react fast.

The wing-pilot system as a pendulum

You are hanging 7-8 metres below a wing on Dyneema lines. The whole system behaves like an upside-down pendulum - energy moves between the wing and you constantly. When the wing surges forward, you swing back; when the wing falls back, you swing forward. Your job is to damp these swings before they become collapses.

PITCH CONTROL · WING-PILOT PENDULUM · THREE STATES ① NEUTRAL wing overhead, calm air brakes: light tension harness: steady push do nothing · listen ② SURGE FORWARD exiting lift, wing dives ahead brakes: SUDDENLY LIGHT harness: pressure DROPS → pull both brakes 25% to catch it ③ FALL BACK entering lift, wing pitches up brakes: HEAVY pressure harness: pressure SPIKES → release brakes, let wing surge fwd
Fig. 15 · Pitch control · the wing leads, the pilot follows · brakes catch the surge, hands-up releases the slow

The four channels of control

① Brake input · pitch & speed

  • Hands up = wing at trim speed (~38 km/h on the Epsilon 9), full pressure
  • Hands at jaw = ~25-30% brake, slight slowdown, wing more bitey in turbulence
  • Hands at chest = ~50% brake, slow flight, near minimum sink
  • Hands at hips = ~80% brake, approaching stall - only for landing flare or active piloting recovery
  • The brakes are also your primary damping tool - use small, fast inputs to absorb pitch oscillations

② Weight shift · roll & turn initiation

  • Always lead the turn with weight shift, then add inside brake - never the other way around
  • Lean by pushing on the opposite footboard (left foot for right turn) and shifting hips, not by twisting upper body
  • On the Epsilon 9, weight shift alone gives a beautiful flat turn - perfect for following a thermal core
  • Pod harness: weight shift is more muted than seat-plate; you need to commit harder with the hips

③ Eyes & head · situational awareness

  • Eyes above and ahead - looking at the horizon, not at the vario
  • Glance up at the wing every 10-15 seconds, especially in thermals or near terrain
  • Scan for traffic - left, right, above, especially before turns. Look where you are turning.
  • Vario is for ears (audio), not eyes. Listen to the beep, do not stare at the screen

④ Speedbar · cruise speed

  • Quarter bar ~ 42 km/h - cruise into light wind, smooth air only
  • Half bar ~ 47 km/h - penetration into stronger headwind
  • Full bar ~ 52 km/h - emergency only, for getting upwind/escape; collapse risk significantly higher
  • Never use bar in turbulence below 200 m AGL - collapses on bar are deeper and recover with more altitude loss

The Epsilon 9 specific feel

Your wing is at the top of its weight range, which gives it a distinct character that you should cultivate awareness of:

  • Solid in turbulence - high wing-loading means more pressure inside the cells, which makes asymmetric collapses less likely than for a lighter pilot on the same wing.
  • Faster recovery from pitch oscillations - but also a slightly steeper dive after a surge. Catch the surge earlier (smaller brake input, faster).
  • Higher trim speed - about 1-2 km/h faster than the same wing at mid-range. This means you penetrate wind better but also need a longer landing flare.
  • Crisper turn entry - the wing responds sharply to weight shift and inside brake. Use less input than you think.
The fifty-flight feel Active piloting becomes intuitive only after about 50 flights of conscious practice - meaning you actively remind yourself "feel the brakes, feel the harness" every flight. After 50, it goes subconscious. Until then, kindly do the deliberate work itself.
Section 09

Thermalling - Spotting, Entering, Centering

A thermal is a column of warmer air rising from a ground trigger. Find one, climb it, leave it cleanly. The skill takes years; the principles fit on one page. Master these and the sky opens up.

Thermals are how you stay up after the ridge lift fades, how you climb to cloudbase, and how you eventually go cross-country. For your first thermal flights, focus on three things in order: spotting them before you fly into one, entering them without getting tipped over, and centering the climb so you stay in lift instead of drifting out.

Spotting thermals before they hit you

Thermals leave a trail of clues - at the ground where they trigger, in the sky where they break the inversion, and in the behaviour of any bird or wing already finding them.

THERMAL ANATOMY · GROUND TO CLOUDBASE PLOUGHED · trigger grass · weak tarmac/road · trigger WIND aloft 12 km/h red kite circling without flap SUN ① Cumulus = thermal top flat dark base = active wispy / collapsing = dying ② Birds circling without flapping strongest single live indicator ③ Column drifts downwind your turning circle must drift too ④ Ground trigger ploughed dirt, dark roads, sunny rocks, south-facing slopes, car parks ⑤ Bonus visual cues · dust devils on dirt · grass moving in waves on a calm day · cloud shadow rapidly moving across ground · another wing climbing for no apparent reason
Fig. 16 · Thermal anatomy · five visual cues from ground to cloudbase, in order of reliability

Entering a thermal - the first three seconds

You will know you have entered a thermal because one wingtip will lift before the other, your harness pressure will spike, and the vario will start beeping. The next three seconds decide whether you climb out of it or get spat out the side.

The entry sequence

  1. Feel the lift on one side - the wing rocks towards the lifted side, harness pressure rises
  2. Turn towards the lifted side - that is where the lift is. Weight shift first, then inside brake to ~25%
  3. Bank gently - about 30° initially. Too steep and you carve out of the lift; too flat and you drift through
  4. Hold the turn for about 270° before reassessing - one full circle minus a quarter, to feel where the strongest beep happens

Common entry errors

  • Turning the wrong way (towards the dropped wingtip) - you fly straight out of the thermal
  • Banking too steeply too soon - you generate sink with the bank before establishing in the core
  • Over-controlling brake input - chasing the beep with brake pumps disturbs the wing without helping centring
  • Looking down at the vario instead of out - you lose orientation of where the lift came from

Centering the climb · the listening turn

Once you are turning, the thermal is rarely centred under you. You need to find the core - the strongest part - and adjust your circle to keep it under the wing. This is done by listening to the beeps:

CENTERING · OFFSET YOUR CIRCLE TOWARDS THE STRONG BEEP ① OFF-CENTRE core to the north of your circle CORE +3.0 +1.2 −0.8 +1.0 strongest beep at NORTH → shift the circle that direction ② CENTRED circle around the core CORE +2.6 +2.4 +2.5 +2.5 consistent climb all around drift with thermal · stay until top or sink
Fig. 17 · Centering · note where the strongest climb happens, then offset the next turn that way

The "drift with the thermal" rule

If the wind is 15 km/h, the thermal is also moving at 15 km/h with the wind. Your turning circle must drift with the thermal - fight the drift and you fall out of the back of the column. Beginners often try to stay over a fixed ground point; that is the wrong reference. Drift with the air, not against it. Cloudbase will be downwind of where you started climbing.

When to leave

  • Approaching cloudbase (200 m below for safety, 100 m below to stay legal) - leave by gliding upwind, not downwind into the cloud
  • Climb rate weakening below half of what it was - the thermal is dying, drift to the next trigger
  • Drifted too far downwind from your retrieve plan - better to take a half-climb and stay reachable than a full climb that strands you
  • Conditions changing - overdevelopment, gust front, cloud street collapsing - get down before the air changes character
The cloud-suck trap Approaching cloudbase, lift can suddenly accelerate from +2 to +5 m/s in the last 100 m below the cloud. This is "cloud suck" and it can pull you into the cloud before you can react. Plan to leave the thermal at least 200 m below cloudbase. If suck starts pulling you in, big ears + bar in opposite direction to the cloud's downwind side. Never enter cloud - disorientation, mid-air collision risk, illegal.
Section 10

Ridge Soaring

The wind hits a hill, has nowhere to go but up, and creates a band of lift you can fly along for hours. Simple physics, sophisticated etiquette - because all the other pilots are using the same band.

Ridge soaring is the bread-and-butter of UK paragliding and the foundation of your home four sites. The lift is reliable, the patterns are predictable, and the danger is mainly in the etiquette - eight pilots in the same lift band, all turning, all watching each other, is where most mid-air close calls happen.

The lift band - where it works, where it does not

RIDGE LIFT · CROSS-SECTION · WIND FROM LEFT LIFT BAND soar here · 50 – 200 m above ridge TOO HIGH · lift fades · drift downwind TOO LOW ground turbulence · launch land here LEE ROTOR never fly here · violent rotor ★ Sweet spot just above & in front of the ridge crest WIND → perpendicular to ridge
Fig. 18 · Ridge cross-section · stay in the green band, never cross to the red side

The ridge rules · who has right of way

These are international rules, learned in your CP training, but they are the most-broken rules in UK soaring on a busy day. Memorise them and apply them before the close call.

Rule 1 · Ridge on the right has priority

If you are flying along the ridge with the ridge on your right, you have right of way. The pilot coming the other way (ridge on their left) must move out of your path - usually by going further out from the ridge.

Memory: "ridge on the right = right of way"

Rule 2 · Overtaking goes to the outside

If you are catching a slower pilot from behind, overtake on the outside of the ridge (further from the slope). Never overtake between them and the ridge - that traps both of you if either has to turn.

Rule 3 · Turn away from the ridge

When ending a beat (running out of useful ridge), turn away from the ridge, not towards it. Turning into the ridge while another pilot is approaching causes head-ons. Turning away gives both of you visual confirmation of the manoeuvre.

Rule 4 · Thermalling pilots have priority over soaring

A pilot established in a thermal turn has the right of way over a pilot soaring back-and-forth. If you join an existing thermal, turn the same direction as the pilot already in it, even if it feels wrong.

Rule 5 · Lower pilots cannot see higher ones

If you are higher, you can see the pilot below - they cannot see you. The responsibility to avoid is on the higher pilot. Never assume a lower pilot has seen you.

Rule 6 · "Eyes out" beats "rules in your head"

All these rules fail if pilots stop scanning. Look left, right, above, below, every 10-15 seconds. Especially before any turn. Especially in a busy lift band. The rule that saves you is the one you do not need because you saw them coming.


Beating the ridge - the figure-of-eight pattern

The classic ridge-soaring pattern is a figure-of-eight along the lift band. Fly along the ridge in one direction until the ridge ends or the lift weakens, turn out (away from the ridge), fly back the other direction, repeat. On a 5 km ridge like Chinnor, one beat takes about 5-7 minutes.

  • Stay in the lift band - keep your altitude above the ridge crest by 50-100 m for sustainable lift, or 150-200 m if conditions allow
  • Turn away from the ridge at each end, into clear air
  • Use thermals when they pass through the ridge band - these come through cyclically and let you climb above the ridge top
  • Mind the masts and pylons - every UK ridge has at least one. Know where they are before launching
  • Bottom-land if blown back - never try to "fight" your way back over the ridge if the wind picks up; land in the bottom field and walk up
The "blown back" emergency If the wind suddenly increases and you cannot maintain position above the ridge, do not try to push through with speedbar in hope. Going behind the ridge puts you in the lee rotor where the wing will likely collapse. Instead, immediately turn out from the ridge, accept the loss of altitude, and land in the bottom field. Walking up is far better than the alternative.

Recognising Danger - Live

Most accidents do not happen because the pilot ignored a warning. They happen because the pilot did not know there was one. The atmosphere telegraphs almost every dangerous change before it lands - these are the signals to memorise and respond to instantly.

The warnings in this section come from the air itself, from the clouds, from the ground, from other pilots, and from your own body. Each one is a "land now, debrief later" trigger - there is no upside to investigating. The pilots who fly long careers all share one habit: they retreat early and feel slightly silly about it for thirty minutes, then feel grateful for the rest of the day.

The eight live warnings

EIGHT LIVE WARNINGS · PATTERN BOOK ① OVERDEVELOPMENT cu growing tall, dark base → thunderstorm in 30-90 min ② GUST FRONT cloud line + wind reverses suddenly → violent gusts within 10 min ③ WIND INCREASING earlier now (horizontal) windsock from droopy → horizontal → blown back risk · land NOW ④ CLOUD SUCK vario suddenly +5, +6 m/s → big ears + bar AWAY from cloud ⑤ CONVERGENCE LINE two winds meet, line of cloud → lift along line + sudden direction shift ⑥ SEA-BREEZE FRONT arc of cloud advancing inland → wind reversal · land before it arrives ⑦ SUDDEN SILENCE vario flatline all vario beeps stop · air goes "dead" → inversion / sea breeze · land within 15 min ⑧ BIRDS FLEEING LOW gulls / kites flying low & fast inland → they know weather is changing SEE ANY OF THE ABOVE? · PROCEED TO LAND IMMEDIATELY · DEBRIEF ON GROUND
Fig. 19 · Eight patterns to memorise · any one of them is a "land now" trigger, not a "let me check" one

The "I do not like this" feeling

The most underrated warning is the one that has no name - the vague unease that something is off. The wing feels different. The air smells different. The sky has gone quiet in a way you cannot articulate. Beginners often suppress this feeling because they cannot justify it; experienced pilots have learnt that the unconscious mind processes patterns the conscious mind has not caught up with yet.

Trust the feeling · land If you feel uneasy and cannot articulate why, that is itself enough. Land. Sit on the grass. Then think about why. Sometimes the feeling was nothing - five minutes lost. Sometimes the feeling was the only warning you got - life saved. The trade is asymmetric in your favour.

Cross-checking with other pilots

If you see warning signs but other pilots are still flying, do not assume they are right and you are wrong. Often the early-warning pilot is the one who survives. Conversely, if other experienced pilots are landing while you are still up, that is data - start your own descent.

Section 12

Useful Descents · Big Ears, Speedbar, B-line

Sometimes you need to come down faster than the wing wants to. Cloudbase pulling you up, gust front incoming, late for a landing window - these techniques get you on the ground quickly without losing the wing.

For your experience level on an Epsilon 9, four descent techniques exist; only the first two should be in your daily kit. The others require coaching before solo use, and the spiral dive is genuinely not yet for you. Each technique has a specific use case - pick the right one for the situation.

The descent techniques · ranked by safety

DESCENT TECHNIQUES · SINK RATE × CONTROL × SKILL REQUIRED ① BIG EARS YOUR PRIMARY ~ 4-5 m/s no twist · easy reset use: avoid cloud, lose height ② EARS + BAR SECONDARY ~ 4-5 m/s + speed moves you forward use: escape upwind from cloud ③ B-LINE STALL AFTER COACHING ~ 6-8 m/s vertical SYMMETRIC release vital ④ SPIRAL DIVE NOT YET FOR YOU ~ 8-15+ m/s 2-4 G · sustained spin
Fig. 20 · Four descents compared · use the leftmost one that is fast enough for the situation

① Big Ears · your daily descent tool

How: reach above the risers, grab the outer A line(s) on each side (one strand if your wing has split-As, two if not). Pull down firmly on both sides at the same time. The wing tips fold inwards, span shrinks, sink rate increases.

Hold: wait until you are at the altitude you want.

Release: let go of one A at a time, then the other (small delay). Wing reinflates progressively. If wing does not reopen on its own, gentle pump on the brake on that side.

② Big Ears + Speedbar · escape with descent

When: you need to escape upwind from a cloud or gust front while also losing altitude.

How: apply Big Ears first, then push the speedbar. Forward speed increases significantly while sink rate stays high.

Watch: push the bar smoothly - do not stomp it. With ears in, the wing has reduced angle of attack already; bar adds more. A collapse on bar with ears in is a complicated recovery.

③ B-line stall · only after instruction

What it is: pulling both B risers symmetrically deforms the wing into a "V" that loses lift. The wing stops flying forward and parachutes straight down at 6-8 m/s.

Why coaching: the symmetric pull is critical - uneven pull induces a spin. The release must be symmetric and sharp; slow release can stall the wing.

For now: book a B-line session at an SIV course before adding this to your toolkit.

④ Spiral dive · not yet

What it is: a banked turn that, with sustained inside brake and weight shift, develops into a spiralling dive. Sink rates of 8-15+ m/s, sustained 2-4 G loading on the pilot.

Why not yet: easy to enter, hard to exit cleanly without "twisting up" or losing too much altitude. Disorientation under G is significant. Wing recovery from over-exited spiral is a real risk.

Pathway: SIV course over water with instructor. Probably 200+ hours and after B-line is muscle memory.

Decision rule for descents Use the safest technique that is fast enough for the situation. Big Ears + Bar at 5 m/s is enough to escape almost any UK weather - do not reach for B-line just because you read about it. Most cloudbase situations resolve with Big Ears alone if you act early.
Section 13

Strong Wind & Gust Techniques

Conditions can build during the flight. The wind that was 18 km/h at launch can be 28 km/h by 14:30. Recognising it, flying through it, and getting down safely are three different skills - all essential.

The Epsilon 9 at your wing-loading penetrates wind reasonably well, but penetration only takes you so far - at some point the wind exceeds your trim speed and you start going backwards. Recognising that point before you cannot reach the LZ is the entire game.

Recognising strong wind in flight

  • Ground track speed dropping - landmarks below moving slower than usual when flying upwind. If your shadow looks like it has stopped moving forward, the wind is matching your trim speed
  • Drift downwind on every thermal happening faster than usual
  • Wing pressure increasing - risers and brakes feeling "buzzy" with more pressure
  • Other pilots being blown back over the ridge or sinking out fast
  • Windsock at LZ looking horizontal and steady (if you can see it)

Flying technique in strong wind

Active piloting · turned up

  • Hands at jaw level, ready for fast input - pre-load the brakes against any pitch movement
  • Watch the wing more often - every 5-10 seconds rather than 15
  • Smaller, faster brake inputs to damp surges before they develop
  • Weight shift instead of brake for any course correction - keeps the wing pressurised

Speedbar · use it strategically

  • Use bar only in smooth turbulent air - not in the gust front itself
  • Quarter to half bar adds 4-9 km/h penetration - often enough to reach the LZ
  • Release bar instantly if you feel the wing about to collapse (lighter brake pressure, surge sensation)
  • Never use full bar below 200 m AGL - collapses on bar are deeper and recover with more height loss

The "cannot make ground" rule

The single most important strong-wind decision: if you are flying upwind on full bar and your ground track shows you moving backwards or holding stationary, do not persist. The situation only gets worse - wind tends to increase as cloudbase lowers. Immediate actions:

  1. Turn 90° across the wind - you stop being blown backwards
  2. Pick the nearest safe field - even if it is not your planned LZ
  3. Land into wind - short ground roll is safer than missing the field
  4. Keep the wing controlled after touch-down - turn around immediately, brake-stall, run forward to collapse the wing before it drags you
Drag after landing · the silent danger Most strong-wind injuries happen after the touchdown - the wing reinflates and drags the pilot through fences, into trees, across rocks. The instant your feet touch, turn into the wing and pull both brakes fully. If still being dragged, run upwind towards the wing to collapse it. As a last resort, grab a C riser and pull hard to deform the wing.
Section 14

Cross-Country Basics

Cross-country is what happens after ridge soaring becomes too small. Climb to cloudbase, glide downwind to the next thermal, climb again, repeat. Simple in concept, lifelong in mastery.

For your home Chiltern sites, true XC is constrained by airspace - Luton CTR caps Dunstable at 1500 ft AMSL, the London TMA caps Chinnor at 2500 ft. Real XC distances start when you visit Long Mynd, Brecon, or the South Downs. The principles below apply to all of them.

The XC cycle · climb, glide, climb, glide

XC PATTERN · CLIMB TO CLOUDBASE · GLIDE TO NEXT TRIGGER · REPEAT CLOUDBASE 1800m +2 m/s 12 min glide @ 38 km/h 2.5 km 11 min 2.4 km → next thermal WIND → Epsilon 9 best glide ~ 9:1 at 38 km/h · with bar 7:1 at 47 km/h · always glide upwind first if conditions worsen
Fig. 21 · The XC cycle · climb to base, glide to next trigger, repeat - distance is the by-product

The eight rules of beginner XC

1 · Always know your retrieve

Never go XC without a driver who knows the route, has your phone number, and a backup if you land somewhere unexpected.

2 · Start with downwind, not upwind

Beginner XC is downwind only - you cover ground easier, stay reachable, and a wind shift does not strand you.

3 · Climb to top of every thermal

Altitude is options. Take the full climb even if it is slow. Half-climbs limit your next glide range.

4 · Glide on a known trigger

Pick the next ground trigger before leaving the climb. Glide directly to it. Random gliding is sink chaser.

5 · Always have an LZ in glide

At every point of the glide you should be able to reach a known landable field. If not, climb to gain options.

6 · Watch the airspace map

UK lowland is full of CTRs and TMAs. SkyDemon or Avenza on the phone, with airspace pre-loaded, before launch.

7 · Land before you have to

If conditions are worsening or you are tiring, land in a good field with daylight to spare. The 2km extra was not worth it.

8 · Phone the retrieve as you land

Three-way SMS ideally - landing field GPS pin, time, condition. While packing, walk to a road and identify a pickup point.

For your area specifically Real XC from the Chiltern home four is hard because of airspace. The standard "first XC" pathway for Aylesbury pilots is to drive to a less-restricted site (Combe Gibbet, the South Downs, or Long Mynd) for XC days, then return to the home four for soaring days. Set a personal goal of 10 km, then 25 km, then 50 km - each step is its own learning chapter.
Section 15

Landing · Approach & Flare

Every flight ends with a landing. Done well, you walk away. Done badly, you limp away - or worse. The approach pattern is the half that pilots usually nail; the flare timing is the half they rush. Slow down, watch the ground come up, time the brakes.

The standard UK landing approach is the aircraft pattern: downwind leg, base leg, final approach into wind. It works because it gives you constant visual reference of the LZ and lets you adjust altitude before committing to the final.

The approach pattern

APPROACH PATTERN · DOWNWIND · BASE · FINAL LANDING ZONE WIND → DOWNWIND LEG · 100m AGL · scan LZ BASE ~ 50m AGL FINAL · into wind no turns below 30m enter pattern touchdown enter the pattern parallel to wind, on the side opposite the LZ flag
Fig. 22 · Three legs · downwind to scan, base to set up, final to land

Downwind leg · 100m AGL

  • Fly parallel to the LZ, with wind behind you
  • Scan: surface, wind direction at LZ, obstacles, livestock, other pilots
  • Last chance to abort to a backup LZ if main is unusable
  • Adjust speed and height to arrive at base turn at ~50 m AGL

Base leg · ~ 50m AGL

  • 90° turn perpendicular to wind, towards the LZ
  • Use this leg to lose excess height - figure-8s if you are too high, straight line if low
  • Eyes on the LZ aiming point throughout
  • Aim to start final approach at 25-30 m AGL

Final · into wind

  • Aligned into wind, wing level, hands at jaw
  • No turns below 30 m AGL - turning low loses lift and creates a hard-edged collision risk
  • Eyes on the touchdown spot, not under your feet
  • Get out of the pod or seat - feet down, ready to run

The flare · timing is everything

The flare converts forward speed into a brief moment of zero sink, dropping you onto your feet from walking pace instead of trim speed. Done early, you balloon up, lose lift, drop hard. Done late, you arrive at trim speed and run hard or fall.

The standard flare

  1. Approach: hands at jaw, no brake, wing flying at trim speed (~38 km/h on Epsilon 9)
  2. 3 metres up: hands smoothly to chest level, ~30% brake. Wing slows, you decelerate
  3. 1 metre up: hands continue down to hip level, full brake. Wing parachutes down for the last metre
  4. Touchdown: feet down, two or three steps, hands stay at hips until wing falls behind
  5. Turn around: immediately turn into the wing, pull both brakes, walk forward to collapse the wing

Flare adjustments by wind

  • Light wind (under 8 km/h): earlier, deeper flare - wing is still moving forward at touchdown, you will need to run more
  • Medium wind (8-15 km/h): standard flare as above - most common UK landing condition
  • Strong wind (15-25+ km/h): shallower flare or no flare at all - wing is barely advancing, you arrive almost vertically. Just touch down and immediately stall the wing
  • Pod harness: get out of the pod earlier - at 50 m on base, not on final. A pod-trapped landing is a knee injury waiting
The PLF · parachute landing fall If a landing goes wrong (sudden gust, mistimed flare, ground rotor), do not try to stay on your feet - you will tear ligaments. Instead: feet together, knees together, roll sideways onto thigh-hip-shoulder. The classic PLF disperses impact across five contact points. Practice it on grass occasionally.

Top-landing · only when ready

Top-landing (returning to the launch field) is an advanced skill. For your home sites, it is regularly done at Dunstable (open field) and Sharpenhoe (small) but rare at Chinnor (one-flight site). At your hours, the right approach is:

  • Watch experienced pilots top-land for several flying days before attempting
  • First top-landing should be on a calm day, with a club coach or experienced pilot watching from the ground
  • The approach pattern is the same as bottom-landing, just smaller - the difference is the consequences of misjudgement (rocks, fences, vehicles right next to the LZ)
  • Bail-out plan: if the top-landing approach goes wrong, immediately fly out front to the bottom field - never try to "fix" a bad top-landing approach
Reference Cards
Section 16 · Reference

Cloud Atlas for Paragliders

Ten clouds you must recognise on sight - what they tell you about the air and whether you should be flying in it.

Cumulus humilis

600 – 2000 m · "fair-weather cu"

Small, flat-bottomed white puffs. The classic paragliding cloud - each one marks a thermal column, base sharp and dark. FLY ideal soaring & XC day.

Cumulus mediocris

800 – 2500 m · "good cu"

Taller than wide, building actively, dark flat base. Strong thermals below, chance of OD by afternoon. FLY with awareness of OD risk.

Cumulus congestus

800 – 5000 m · "tower"

Tall cauliflower-shaped, dark base, growing visibly. Strong thermals but on the edge of overdevelopment. CAUTION land within 30 min if any one shows signs of growing into CB.

Cumulonimbus (CB)

500 – 12,000 m · "thunderhead"

Huge, anvil-topped, very dark base, often with rain or hail visible underneath. STOP instant land - gust fronts radiate 20-30 km. Lethal to paragliders.

Stratus

0 – 1500 m · "the lid"

Featureless grey sheet, often with the hilltop in cloud. Visibility low or nil. STOP no thermals possible, IMC danger, often drizzle.

Stratocumulus

600 – 2000 m · "lumpy lid"

Lumpy grey layer with breaks. Often signals an inversion - thermals trapped below. CAUTION if breaks are widening, day may improve; if closing, will become stratus.

Altocumulus

2000 – 6000 m · "mackerel sky"

Mid-level, organised in waves or patches. Often indicates an approaching front 12-24 hours away. Can also indicate turbulence at that altitude. CAUTION

Cirrus

5000 – 13,000 m · "horsetails"

High, wispy, ice-crystal clouds. By themselves harmless to paragliders. But if cirrus thickens into cirrostratus over hours = warm front incoming in 18-36 hours. FLY today, plan tomorrow.

Lenticular

2000 – 8000 m · "lens"

Smooth, lens-shaped, often stationary above mountains - the visible part of a mountain wave. Indicates strong wind aloft and severe turbulence in the lee. STOP mountain flying off the table for the day.

Roll cloud (gust front)

200 – 1500 m · "horizontal tube"

Long horizontal tube of cloud advancing. Marks the leading edge of cold outflow from a thunderstorm - often 10-30 km ahead of the storm. STOP immediate landing within minutes - the gust hits hard.

Section 17 · Reference

Weather Systems Quick Reference

Seven synoptic patterns that govern UK paragliding weather. Recognise them on the morning chart and you will know what kind of day to expect before the forecast even loads.

High pressure · "anticyclone"

Settled summer high

Light winds, clear skies, slow heating. Good for thermalling once the inversion lifts (~midday). Risk: sea breeze fronts in the afternoon, especially in southern England. Best days of the year.

Low pressure · "depression"

Active low

Strong winds, fronts, rain. Cyclonic flow brings unstable air. Generally not a flying day, though the brief gap between fronts can be excellent - pilot beware of the next front arriving sooner than forecast.

Warm front

Approaching warm front

Cirrus thickening over hours, then altostratus, then nimbostratus and rain. Conditions deteriorate over 12-24 hours. Fly early in the day before the cloud lowers - but the air is often unstable just ahead of the front.

Cold front

Cold front passing

Fast-moving line of CB or strong cumulus, often a wind shift of 60-90° as it passes. Heavy rain, gust fronts, possible hail. Land before it arrives. Flying often resumes 2-4 hours after the front clears, with cool unstable post-frontal air.

Occluded front

Occluded front

Cold front catches up to warm front. Multiple cloud layers, persistent rain, low cloudbase. Generally not flyable. Pattern often clears slowly over a day before the next system arrives.

Ridge of high pressure

Ridge between systems

Brief 12-36 hour window of settled weather between two systems. Often the best XC days of the year if it coincides with summer heating. Watch for the next system arriving by the end of the day.

Trough · convergence line

Trough of low pressure or convergence

A weak trough or convergence line creates a band of enhanced thermal activity and lift along its length - sometimes producing dramatic streets of cumulus. Brilliant for XC if you stay on the right side of the convergence; brutal turbulence if you cross it. Read the surface chart carefully and identify the line on Meteo-Parapente before launching.

The morning routine Open the Met Office surface pressure chart (the "synoptic chart") every flying morning. Find the UK on it. Identify which of the seven patterns is dominant. That single observation will frame everything else you read in the day's forecast - wind, cloudbase, stability, and the timing of changes.
Section 18 · Reference

Personal Decision Matrix

Cross-reference the day's conditions against your current ability to make a clear, defensible go/no-go call. Print this, stick it in your harness pocket, look at it on every flying morning until the rules become reflex.

Condition GO CAUTION (with conditions) NO-GO
Surface wind on launch 12-22 km/h straight on 8-12 or 22-25 < 30° cross < 8, > 25, or > 30° cross
Wind aloft (700hPa) < 25 km/h 25-35 km/h with shorter flight plan > 35 km/h blown-back risk
Gust factor (max ÷ avg) < 1.3 1.3-1.5 if launch is open > 1.5
Cloudbase AGL > 1000 m 600-1000 m stay below 200m of base < 600 m
OD potential < 30 % 30-50 % land before 14:00 > 50 %
Visibility > 10 km 5-10 km stay near launch < 5 km illegal anyway
CB or rain anywhere none within 50 km distant only & moving away any approaching
Your sleep last night > 7 hrs 5-7 hrs first flight only < 5 hrs
Last flight was when < 14 days 14-60 days ground handle first > 60 days retraining flight
Other pilots in air 3-8 flying calmly 1-2 flying watch them none on a forecast-good day
The traffic-light rule Any single STOP = no fly. Two or more CAUTION = no fly. One CAUTION + everything else GO = fly with the noted modification (shorter flight, stay near LZ, land earlier). Be honest with yourself when filling this in - the matrix only works if the inputs are not optimistic.
Section 19 · Reference

Site-Type Flyable Conditions

Different site types want different conditions. The same forecast that is perfect for an inland ridge can be useless on a coastal site, and dangerous in the mountains. Cross-reference before driving.

Site type Wind speed sweet spot Wind direction tolerance Cloudbase needed Best time of day Special notes
Inland ridge
Dunstable, Sharpenhoe, Chinnor, Combe Gibbet
12-25 km/h ± 30° of ridge perpendicular > 600 m AGL 11:00 - 16:00 Thermals can be strong but air is generally well-ventilated. Watch for OD on hot days.
Coastal cliff
Beachy Head, Mount Caburn (partial), Devil's Dyke
15-30 km/h ± 20° of cliff perpendicular > 400 m AGL OK any · sea-breeze driven Lift is smooth and reliable but limited in altitude. No thermals usually. Sea breeze can switch direction in evening.
Mountain
Long Mynd, Brecon, Lake District
10-20 km/h ± 25° of slope perpendicular > 1000 m AGL 10:00 - 17:00 (XC) · evening glass-off More turbulence behind ridges, valley winds can dominate, cloudbase critical for safe XC. Weather changes faster.
Flat-land tow
Rufforth, Sutton Bank tow
8-18 km/h steady direction needed > 800 m AGL 12:00 - 16:00 Pure thermalling - no ridge lift to fall back on. Strong day required. Tow operator's call governs.
Bowl / amphitheatre
Frocester, parts of Long Mynd
10-22 km/h ± 45° (bowl catches wider range) > 600 m AGL 11:00 - 16:00 Forgives off-axis wind better than a flat ridge. Thermals can converge inside the bowl - strong climbs.
One-flight site
Chinnor, some Brecon sites
12-22 km/h ± 20° > 400 m AGL any flyable window No top-landing back to launch. Plan the bottom-LZ extra carefully - it is the only LZ. Retrieve walk-up time matters.
For your home four Dunstable (SW 240°), Sharpenhoe (ENE 060°), Chinnor (NW 320°), Ivinghoe (W-SW). Together these cover wind directions from north-west through south-west to east-north-east - about 60% of UK wind directions are flyable on at least one of them. The remaining 40% (south, south-east, north, north-east) means a longer drive - Combe Gibbet for S/SE, Long Mynd for N/NE.

Post-Flight Debrief Card

Five questions, asked while the wing is being packed and before the drive home. Answered honestly, they turn each flight into a lesson - and after a hundred flights, into actual skill.

Most pilots learn fastest in the first 50 hours, then plateau. The plateau is not because the air becomes less interesting - it is because they stop debriefing. Five minutes of reflection after every flight, written down somewhere, compounds over a flying career into the difference between a careful pilot and a great one.

Five questions · ask in this order

① What went well?

One specific thing - not "the whole flight was nice". A particular launch, a clean thermal entry, a good decision to land early, a smooth top-landing. Specificity matters because the brain encodes specifics, not generalities.

② What went badly · or could have gone badly?

Honest answer - the launch that nearly cravat-ed, the descent that started 100 m too late, the moment you turned the wrong way in a thermal. Near-misses count as much as actual mistakes.

③ Three things I learnt today

Three small observations, not big abstractions. "The Sharpenhoe windsock lies - actual wind was 10° more south", "I find lift better with weight shift than brake on the Epsilon 9", "I wait too long to pull big ears - start at 200 m before cloudbase, not 100 m".

④ One specific thing for next session

A single intentional focus - "next flight, I will keep eyes up through the reverse turn", "next flight I will commit to centering instead of jumping from thermal to thermal". One thing, focused on, becomes a habit.

⑤ Did I match the forecast to reality?

Note the morning's forecast (RASP cloudbase, Meteo wind, gust factor) against what actually happened. Over 50 flights, you will know which model is reliable for your area - that knowledge is gold.

Where to write it Notes app on the phone is fine. A small flying log book is better. The point is that you can read back over the last twenty flights and see patterns - recurring errors, slow improvements, sites you fly well at, sites you struggle with. Patterns are invisible without the record.

Emergency Quick-Reference

When something goes wrong, the brain narrows. There is no time to read a manual or remember training notes. The actions below are short, sequenced, and designed to be readable in the 3 seconds before reacting. Memorise them once, refresh annually.

Universal rule · LOOK · ACT · COMMUNICATE Every emergency response in paragliding follows this order. Look at the wing first (assess what is happening). Act on the appropriate technique. Communicate only afterwards (radio call, hand signal). Reverse this order and you make things worse. Reserve toss is the one exception - it is "act first, look later".

Asymmetric collapse

1

Weight shift to the open side - immediately, before adding any brake. This is what stops the wing turning into the collapsed side.

2

Hold opposite brake at chest level on the open side - not too deep, just enough to prevent the wing diving into a spiral. Keep the open side flying.

3

Wait for the collapsed side to reinflate (1-3 seconds). Most EN-B collapses self-recover. Resist pumping.

4

If it does not reopen in 3 seconds, gentle pump on the brake of the collapsed side - long, slow, full-arm pumps, not quick stabs.

5

Once recovered, assess altitude - land if low, continue if comfortable. Note the trigger (rotor, thermal edge, gust) for the post-flight debrief.

Cravat (wingtip caught in lines)

1

Stop the rotation first - weight shift hard to the opposite side, opposite brake to control direction.

2

Identify the trapped tip - if visible, locate the stabilo line (outermost line on that side).

3

Pull the stabilo line firmly downwards - usually frees the cravat in 1-2 pulls. Do not pull other lines randomly.

4

If still cravat-ed and altitude is low (< 100 m AGL) or rotation cannot be controlled, throw reserve. Cravats can develop into deep stalls or sustained spirals.

Spin · stall · twist

1

Spin (one wingtip stalled, other flying): instantly release both brakes fully. The stalled side will reinflate. Be ready for a forward surge - catch it with light brake.

2

Full stall (whole wing parachuting): hands UP and HOLD. Wing will surge forward dramatically, pendulum back, then resume flight. Do not pump brakes during recovery. If it persists or altitude is critical, throw reserve.

3

Twist (you spinning under the wing): bicycle-kick legs in opposite direction to untwist. Reach above the twist for the risers and pull yourself around. Do not use brakes while twisted - they may be wrapped.

Reserve deployment

1

DECIDE. Reserve is for: spin/stall not recovering, sustained cravat with low altitude, mid-air collision, severe twist. Do not deploy if recoverable through normal technique.

2

LOCATE the handle with eyes (not just hands). Confirm what you are about to grab.

3

PULL firmly downwards and outwards in one motion. Do not jerk repeatedly.

4

THROW the reserve packing as hard as you can away from yourself, ideally into clear airspace below the spinning wing.

5

DISABLE the main wing - pull one set of B or C risers down to your harness to collapse the main, or it will fight the reserve and induce downplaning.

6

PREPARE for landing - feet together, knees bent, full PLF position. Reserve descents are 5-7 m/s - equivalent to jumping from a first-floor window.

Landing in the wrong place

Tree landing

  1. Aim for the centre of the largest tree, not the edge
  2. Feet and knees together, arms crossed across chest, chin to chest
  3. Do not flare - let the tree catch you, the flare drops you to the bottom branches
  4. Once stopped, do not climb down - wait for help, ropes can fail. Phone for rescue.

Water landing

  1. Approach into wind for slowest speed at touchdown
  2. Unclip karabiners before hitting water - wing will sink onto you
  3. Inflate any flotation, swim away from the wing immediately
  4. Wing recovery secondary - your life is primary

Wires / pylons

  1. If contact unavoidable, aim to parallel the wires, not cross them
  2. Feet together, no metal contact between wires

  4. Power companies have specific paragliding rescue protocols - phone 999, request power-off

Lines wrapped after bad landing

  1. Do not stand up if lines are around legs or neck
  2. Cut yourself out - every pilot should carry a hook knife in the harness

The pilots who fly long careers all do these things; the pilots who don't, often do not get the chance to.
