Club Coaching

The Dunstable Hang-Gliding & Paragliding Club has several hang-gliding and paragliding Club Coaches. Some Coaches fly both hang-gliders and paragliders. Not all are available midweek, but please remember they are all volunteers and some are far more available and active than others.

Once you have achieved your Club Pilot rating with the school, just get in touch with our Coaches. We leave it entirely up to you to get in touch with us. Many pilots use the Club Facebook Group or Telegram Group to make arrangements and then make last-minute phone calls to Coaches and other members. Try to stay current and get out flying as much as you can in the first year. We see so many low airtime pilots turn up at Dunstable, struggle to fly for a few visits, and then they disappear never to be seen again. Dunstable is a tricky site to fly - but stick with it and master it, it will make you a better pilot for it!

We organise various coaching events throughout the year to assist new pilots in our club:

  • Low-airtime / New member evenings: This is where you can meet the Coaches and discuss coaching tips for flying at Dunstable. Usually held at the start of the year around February/March.
  • Summer weekends away to other suitable sites: Usually Rhossili, the Blorenge, Pandy, Long Mynd etc. However, recently as more and more clubs are struggling with site sensitivity, many clubs are insisting on membership to fly their sites, which makes it difficult to take non-members for coaching.
  • Flying holidays in UK and abroad: Usually organised between our club members themselves and notified on the Club Facebook page. Talk to pilots on the hill who are organising trips.
  • Parachute packing evenings: Organised in February and supervised by a BHPA qualified re-packer. These evening are for you to self-pack your reserve, under the supervision of the qualified repacked, you do not receive a repacking certificate. The Thames Valley Club organise the Big Fat Repack in early March and they have repackers that will pack your reserve for you, so if you require a certificate you should attend this event.
  • Lectures and BHPA Exams for Pilot, Advanced Pilot: These lectures are geared towards Club members wishing to take the BHPA 'Pilot' or 'Advanced Pilot' Rating. Held in the early Spring or Autumn evenings, these lectures (Airlaw, Flight Theory, Meteorology) are held on four consecutive weekly sessions, with the actual exam held on the forth evening (for those that are taking the exam). Make sure that you have all your flying tasks signed-off in your BHPA Task Book by a Club Coach - before sitting the exam.

Pilot Lectures & Exams

Getting your tasks signed off for passing the BHPA Pilot Rating

Club Lectures and Exams for the BHPA Pilot (P) Rating. These lectures are geared towards Club members wishing to take the BHPA 'Pilot' rating. Held in the early Spring or late Autumn evenings. These lectures are open to ALL our club pilots (Low airtime pilots are especially welcome, even if you're not ready to sit the Pilot exam yet). The three lectures are on Airlaw, Flight Theory and Meteorology, and we do one a week for three weeks and sit the exam on the forth week. Make sure that you have all your flying tasks signed-off in your BHPA Task Book by a Club Coach - before sitting the exam. You should have been issued with a Task Book when you left the School or get one direct from the BHPA.

PLEASE NOTE: Pilots sitting the exam MUST have completed ALL the tasks in the Task Book and had them signed off by a Club Coach or Instructor BEFORE sitting the exam. The BHPA requires all tasks to be signed off before sitting the exam. Pilot Task Books are available from the BHPA office.

The Pilot exam paper is sub-divided into the three sections (Airlaw, Flight Theory & Meteorology). All three sections must be be attempted during the 1 hour 45 minute time period allowed. The exam is multiple-choice and has a pass mark of 70%. Pilots failing the exam have to wait 4 months before they can re-sit the whole exam again.

So…make sure that you get your tasks signed off by a Club Coach on the hill. Just mention to the Coach that you would like him/her to witness your flight task and the Coach will sign your Task Book (Pilot Task books are available from the BHPA Office).

Other documents can be downloaded here direct from the BHPA website.

On the Hill

Advice from the Lead Coach for your first few visits to the Downs

The main Club Coaching done within our Club is simply to come out flying on the hill, with either the Club Coaches themselves, or talking and flying with more experienced pilots. When you turn up ask for a Club Coach and explain that you are new to the site and maybe need a bit of help. Tell the Coach your experience in hours airtime and the last time you flew. Remind the Coach if you are flying the site for the first time.

Read through the coaching sections below, 'The Launch and the Fence', 'The First Third' and 'How wind direction affects flying the ridge at Dunstable', and especially 'Danger Days', these will give you valuable insite on flying here at the Downs. If you are at all unsure about any aspect of the advice given - ask a Coach on the hill.

When you first arrive on site

We presume you have thoroughly read the Dunstable Site Guide and know the various launching and landing areas. Yes, I know everyone is taking-off at the main paraglider launch in front of the fence, but - is that the best place for you to launch from?

Spend at least 20 minutes just looking around the site itself, look where the experienced pilots are flying - how they launch - where they launch - how they top land. Check the windsocks in the Gliding Club, is the wind off to the North or the South? How will that affect your groundspeed? Which way do you turn after launch?

Also look at the sky. What are the clouds telling you? Are they flat and layered or towering up into the blue sunny sky with crisp edges. What are the birds doing? Are there flocks of them all circling at once? Are some pilots in the air much higher than others? This is an obvious indication of thermals on the hill. Watch and Learn!

All this visual information can give you advanced warning of what the air is going to be like, even before you take-off. Finally, make sure YOU are ready to fly, and that you are well rested after your stressful drive to the site, and above all remain focused on what you are about to do.

Finally a word of advice…forget the GoPro's, cameras and the Selfie-sticks, concentrate on just your flying. Leave all that tech on the ground for when you have more flying experience.

Make sure you have a Flight Plan. 

What exactly do you want to achieve with your first flight? Do you want to do a straight top to bottom or maybe soaring above the hill and a top landing? Don't be too ambitious with early flights at the Downs, it's a technically difficult site to fly and you may end up going down to the bottom field on your first few flights. We have all learned that way, every single pilot you see effortlessly flying the hill has been through the same situation as you are now in. Digest all the visual information you collected earlier, ask questions with the Coaches if needed and finally, plan it in your head before you launch and above all stick to your Flight Plan!

Remember: Pilots with less than 10 hours need to discuss their flight plan with a Club Coach on site before flying. Please remember that Coaches also want to fly, they don't need to waste an hour on the ground waiting for you to pre-flight your harness and wing, get all that stuff sorted beforehand, then ask for help.

At some point you will be wanting to take-off from the main paraglider launch in front of the Club car park. The dreaded fence seems to be a major obstacle for some low airtime pilots, but with good technique it will become a lot easier. The next article below gives some good advice…

 

The Launch and the Fence!

Coaching tips for low airtime pilots launching over the Fence

The majority of low airtime pilots we see at Dunstable, have difficulty launching over the Fence because they get the ground-handling all wrong. Their ground-handling skills are lacking practise and polish. Most of these pilots just seem to pull on the brakes expecting to launch into the air and fly. This may happen at other sites you visit (Combe Gibbet / Devils Dyke) where the launch point is inside the hill's lift band, but Dunstable is completely different, our main launch is outside the hill's lift band. Take a close look at the images…

The Hill Lift Band

The main paraglider launch in front of the Club car park is fairly flat and away from the hill slope (see the images). Subsequently, it is out of the lift band of the slope. You will only get ridge lift once you cross the Fence. 

The Venturi (compression) wind coming over the crest of the hill has a lot of horizontal component to it, making moving forward in any strongish breeze fairly difficult. So in a steady 10mph breeze the actual windspeed on the launch might be 14+mph, and possibly 20+mph if strong thermals are coming through. So make sure that you launch fairly near the fence (Point A). This gives a better chance of a successful launch.

Remember to keep your hands well up and not to apply the brakes, you will get only get dragged backwards or prematurely launch into the air and then go backwards! For the same reason do not launch too far back from the fence (Point B), as you can soon get out of control and will get dragged backwards towards the wooden posts, cars and onlookers!

For a successful launch you need three things…SPEED, SPEED and more SPEED!

How it's done

The technique is to get your launch speed correct. Keep your hands / brakes well up and really lean forward whist running towards the fence. Plenty of speed as you approach the fence, a big final push off with your feet, then dab both brakes a touch as you cross over the fence and this then converts your speed to lift, to help you clear the fence. (The Speed Squared Law: double your speed and lift increases four times - treble your speed and the lift increases nine times!)

There is no hill lift on the launch side of the fence. Do not just pull on the brakes, you will just go up and backwards, and then come down and collide with the fence. You will only gain height after you clear the fence! If you do take-off too slow and manage to scrape over the fence, then you will either drop into the gulley and sink halfway down the hill or immediately land again in the gorse bushes on the other side of the fence.

We will now look at actually flying the hill (assuming that you have successfully cleared the fence) and where to fly in order to actually stay up and soar the hill. You now switch instantly from 'Launch Mode' (getting over the Fence) to 'Flight Mode' (staying up on the hill) using a trick I call: The First Third.

The First Third

Advice for low airtime pilots struggling to fly at the Downs

You may remember at the New Members evening we talked about 'The First Third' for Ridge Soaring at Dunstable. The following information is intended for low airtime pilots new to the site struggling to ridge soar at the Downs. The diagram and advice shown here, is for wind speeds of about 10mph or less - typical of the windspeed in the early morning or evening (or the max windspeed you would be happy to fly in for your first few flights).

 

Note: As the wind speed increases above about 12mph+, the Lift Band of the hill gets larger and therefore, the "First Third / Magic Area' expands out with it. So you can fly a bit further out away from the hill. I am assuming here that you are not going to try your first flights in a 15mph wind!

If the wind does pick up to 15+mph while your in the air, you must stay well out away from the hill in order not to get blown backwards into the Golf Course. In those situations you will still be in the Lift Band when you are over the Gliding Club perimeter fence! Look down at the ground, are you moving forwards with your brakes fully off and your hands up? If you're not, it's time to bottom land! Beware of top landing if you are being blown backwards as it is in the compression zone, you must quickly use 'Big Ears' to lose height, and fly out to bottom land.

The Pimple 'Bowl' and strong winds!

If the wind speed picks up while you are in the air do not fly behind the walkers track along the top of the Downs, especially near the Bowl. The Pimple can get really nasty in strong winds, as the wind is swirling around the bowl, as you would expect. The Venturi Compression wind over the crest of the ridge can be so strong that even full Speed Bar and Big Ears will not save you from going backwards over the houses and powerlines behind the road.

NEVER fly in the Bowl in strong winds!

The Magic Area: If we take the hill and divide it into thirds, with the top third being the fence on launch and the bottom third at the base of the hill, we can see that the optimum lift band for soaring the hill will be roughly on the first third (where the hill is steepest). This I call the 'Magic Area' - and if you stay within this area you are guaranteed to stay up, depending on a reasonable wind speed of course!

How it's done.

  • Start turning right immediately after launch, you need to follow the Red arrow (A) and be flying above and slightly in front of the trees to the right of the main launch. This puts you directly over the First Third - stay there!!
  • If you launch too slow or fly straight out too long, then you will sink down the slope following the Blue dashed line (B) and you will be between the second and third 'Third' halfway down the hill. if you try and ridge soar that far down the hill - I guarantee that you will be in the trees! The best option is to bottom land and try again, this time concentrating on your launch speed.
  • To maintain your height on the 'First Third' when you turn back to fly along the ridge again, do a "Figure of Eight' turn, where you turn more than 180 degrees so that you are back over the steepest part of the hill.
  • When you have enough height above take-off you can explore along the ridge a bit further, or even contemplate a top landing.

How wind direction affects flying the ridge at Dunstable

Dunstable can take quite a large variation in wind direction, all the way from Southwest through to Northwest and we will discuss each direction in turn.

For the low airtime pilot knowing where to fly in different wind directions is just as important as learning how to fly the hill. Being on the correct part of the hill will make soaring the ridge so much easier. The best wind direction for inexperienced pilots is WestSouthwest to WestNorthwest. When the wind is more off to the Southerly or Northerly extremes then the site becomes much more difficult to fly, and more experience is required to fly the ridge.

 

Southwest Winds: When the wind is off to the Southwest the ridge from the main paraglider launch all the way to The Pimple 'Bowl' is the place to fly. The various gulleys along that part of the hill can give good lift due to thermals/wind coming up them. Whichever way the wind is coming from, either the South or North, then the wind-facing side of the gulley will give lift. Remember, do not fly in the Bowl if the wind is strong enough to stop you flying forwards - so check your groundspeed!

One important point to remember, if the wind has a lot of South in it when taking off at the main launch, and you then turn right towards the Bowl, you will be flying downwind as well as being fairly low over the bushes in order to stay on the 'First Third' - this will test your skill. Always have a 'Plan B' option to be able to turn out from the hill and bottom land safely.

Please Note: Wind directions and site conditions may change during the course of the day, especially when a warm front is approaching and the wind 'backs' towards the south. Pilots should check the windsocks in the LGC for an indication of wind direction and re-assess your flight plan accordingly.


West Winds: When the wind is Westerly the ridge is flyable all the way along from the Pimple 'Bowl' all the way down to the White Lion at the Zoo. Again various gulleys along the ridge can give good lift due to house thermals/wind coming up them. However, beware of being trapped in these gulleys if the wind picks up, as you will be rapidly blown backwards towards the road. If the wind does increase whilst you are flying - do not fly behind the walking path that runs along the top of the hill! 

Always stay well out in front of the ridge when flying in strong winds!

In order to get to the powerline part of the ridge, gain height to the left of the main paraglider launch and then fly over the 'Elephant' as fast as you can, as this part of the hill faces N/W and gives limited ridge lift. Using speedbar can help. Once on the southerly face of the 'Elephant', that should give you enough lift to jump the gulley at the old northwest hang-glider take-off, over to the pylons.

Click on the image to enlarge

Remember - do not get low in front of the Pylons, especially if the wind is strong, in case you get blown backwards towards the high-voltage cables. You will need at least 200ft+ above take-off to jump over both sets of pylons safely to get to the Zoo end.


Northwest Winds: This is the most difficult wind direction for low airtime pilots. You are launching and turning left - flying away from a safe landing in the bottom landing field, and once you reach the 'Elephant' part of the hill, you will not make the bottom field from there, as you will be flying into a headwind and going down fast!

You MUST be able to confidently soar and top land the hill if you are going to fly in a Northwesterly. Once near the Pylons on the ridge there are no bottom or slope landing options available.

NEVER take-off from the Southwest Launch or fly in the Bowl in a Northwesterly wind. You are flying in Rotor from the Pimple! Inexperienced pilots should not fly this end of the hill at all, turn back towards the main paraglider launch before you reach the first gulley.

Therefore, it is recommended that low airtime pilots who need to bottom land in the official fields - do NOT fly at Dunstable in a Northwesterly wind.

Danger Days

We have all read the warnings in SkyWings at the start of each season about spring thermals and accidents to rusty pilots who have had a winter break from flying.

These warning are by all means still current, statistics bear out these warnings. Every Spring there are crop of incidents caused by low airtime and sometimes more experienced pilots flying in unsuitable conditions through not accessing weather conditions correctly or not studying the site conditions.

Meteorology tells you that a thermal will continue to rise as long as it is warmer than the surrounding air. It will then cool and expand until its temperature equals that of the surrounding air. As the thermal temperature gets close to the surrounding air temperature, the thermal slows and stops rising. If the dewpoint temperature of the air is reached a Cumulus cloud will form, this is Cloudbase. If the dewpoint temperature is not reached then we have a 'Blue day' - rising thermals but no clouds forming.

So… if the night time temperature is unseasonably cold and the day is forecast to be hot - expect strong thermals! This will happen more often in summer when the wind has a Northerly track (NW-N-NE), the cold polar airmass coming down across the country combined with strong sunshine, make thermals rise very quickly from the ground.

One particular type of day probably causes more incidents than most and is of special note to Low airtime (Red ribbon) pilots. Make sure you read and understand the causes outlined here.

These… I call 'Danger Days'

The day's scenario is that we have a hot dry (25˚C+) Spring / Summer day, usually with a High Pressure system over the south of England and therefore a low windspeed of 5mph or less or even calm conditions.

Experienced pilots know that with full sun on the ground that thermals will be coming up through the surrounding stable airmass, if there is strong solar heating of the thermal source and if the trigger temperature of thermals has been reached. This gives the opportunity to time your launch and gain height in these rising strong thermals.

These also seem to be the days that low airtime red ribbon pilots seem to flock to the hill, with little airtime gained over the previous months. The low windspeed and the sunshine encourage them to all turn up at the hill around midday (the hottest part of the day), all expecting to fly!

It is the total inexperience of these low airtime pilots that contribute to any accident that may happen. Accidents do not just happen. I believe that accidents are the result of three previous bad decisions, and the third result is the accident itself. It can be pressure to fly from others or family present at the time. Or driving a long way to the site and not wanting to just sit and watch. Or even actually launching into conditions that you have no previous experience of. Do not become a statistic, progress slow and steady, wait for a better day!

Earlier, I called them Danger Days - Why?

Well just think about it for a minute and study the background meteorology.

  • Spring can still give coldish nightime temperatures and the higher sun in the sky can heat up the ground considerably to give air temperatures of 25˚C+. So, we have a large temperature difference between the cooler surrounding air and the rising thermal temperature. This makes the thermal just leaving the ground rise and accelerate very quickly!
  • Add to this mixture the High Pressure stable airmass, which as you may know, the airmass of a high pressure system is always descending. This is why we have fewer clouds - the descending air warms as it sinks, drying out the moisture in the surrounding air, which inhibits cloud formation. Hence, we get clear blue sky summer days!
  • So… we now have a rapidly rising thermal combined with an opposite stable descending airmass. One airmass going up - one airmass coming down! Therefore, the boundary air layer between these two air-masses will be extremely turbulent and our thermal will get very rough at the edges. This can lead to major asymmetric tucks of the wing in this turbulence, which is particularly dangerous if you are low down close to the hill, and active handling is required to cope with these conditions.

Even launching into these thermals require correct timing, before the actual thermal hits the hill, as the boundary windspeed on launch can increase considerably. Once airborne this entails flying very low and close to the hill waiting for the approaching thermal to lift you up.

This is where the majority of inexperienced pilot accidents occur.

Inexperienced low airtime pilots think this wind speed increase as the thermal arrives is normal background ridge lift wind and try to soar the hill, totally ignoring the thermal. These beginners consequently fly straight through both boundaries of our rough thermal and try to fly along the Ridge. Passing through both boundary layers of this rough thermal can cause major wing collapses and tucks - and as you are very low down and close to the ground there is little time for recovery. Experienced pilots will always stay inside the thermal and gain enough height to combat any turbulence, they know there is no ridge lift and therefore not to stay low down too long. So - be warned, if you do choose to fly on these days… 

Do not fly low and slow in these conditions!

In Conclusion: Low airtime pilots - beware of flying on hot calm summer 'Danger Days'. These are probably not the days that low airtime pilots should be flying. If the wind is 5mph or less there will be no ridge lift, only thermal lift - do NOT confuse the two!

Wait for a better evening with a steady 8-10mph wind on the ridge to get some airtime.
