Trevsked Posted February 5, 2019 Share Posted February 5, 2019 I’ve seen this on landing at Membury by at least one person but looking at YT it seems to be used mostly by paraglider pilots. What’s the theory here? Trevor. Quote Link to comment Share on other sites More sharing options...
admin (Simon W) Posted February 6, 2019 Share Posted February 6, 2019 It's a Paragliding technique which can be used when it's very windy to attempt a top landing. I know exactly who you are on about (the bunch) and I have no idea why they have started doing it. It can be dangerous depending on loading and conditions. It 'May' be a bit like a new racing driver (testing the corner before committing, rather than just committing) I think it is more likely that someone saw it, tried it, and now its spreading like an STD lol SW Quote Link to comment Share on other sites More sharing options...

Mark Pugh Posted February 6, 2019 Share Posted February 6, 2019 As a paraglider pilot from years ago (my last new competition wing is 23 years old!) we would use this technique to come down on a spot landing. The glide was so good on a paraglider that it was difficult sometimes to get down that last 3 metres as you watched the end of the field getting closer and closer; or as you were about to fly over the spot in a spot landing competition. So you came in a bit high, and reached for the stall point, then let it fly again, reached for the stall point and let it fly again, reached for the stall point, etc. This would greatly reduce your final few seconds of flight and you came down heavier at a larger angle of fall. This is not needed with an engine on your back, you are generally flying a smaller wing and you are heavier due to the engine weight, your glide with engine off will never match a competition paraglider wing! Therefore you can work out the final glide angle and be much more likely to land next to your car. Reaching the stall point is an exercise best done at a great height. Generally you can't just release it immediately and hope it will all work as a wing again. We were taught, to hold the full stall in until you were dropping back under the wing, ready for release. But each wing reacts differently. 1 Quote Link to comment Share on other sites More sharing options...
jock Posted February 6, 2019 Share Posted February 6, 2019 someone will end up with broken legs or back doing this, This is a pg only trick for landing on hill as simon said,dont do it with a ppg Quote Link to comment Share on other sites More sharing options...
admin (Simon W) Posted February 6, 2019 Share Posted February 6, 2019 In this case (The people referred to in this thread) it's more of a pointless flapping and not the actual technique used by PG pilots in high wind. (basically taking up the slack +2" and letting it go) at a silly fast rate which the wing would not respond to. SW Quote Link to comment Share on other sites More sharing options...
Trevsked Posted February 6, 2019 Author Share Posted February 6, 2019 Thanks all, I wasn’t going to try it but was interested to hear why some used it. Trevor. Quote Link to comment Share on other sites More sharing options...
norbertflyer Posted February 9, 2019 Share Posted February 9, 2019 Just degrades glide (L/D) ratio. Only used for forced tight spot landings and forced top landings in strong winds on a PG. Should never be used with a reflex PPG. Echo Jock's comments on "dangerous". Richard Quote Link to comment Share on other sites More sharing options...
jock Posted February 10, 2019 Share Posted February 10, 2019 Did not someone break his back at ppg comps doing excactly this,pumping brakes and fell 40ft Quote Link to comment Share on other sites More sharing options...
Mark Morgan Posted February 11, 2019 Share Posted February 11, 2019 pointless exercise and does nothing At all... A mate of mine does it but don't know why.. You get a much better landing coming on full fast. Not for New pilots but can be learnt in small progressive stages.. Once you have done it you will never go back to landing on slow trims..

Trevsked Posted February 11, 2019 Author Share Posted February 11, 2019 Thanks all again for explaining. I do need to understand and use the energy available on landing, more flying needed. Trevor. Quote Link to comment Share on other sites More sharing options...
norbertflyer Posted February 11, 2019 Share Posted February 11, 2019 It does do something - it degrades glide, but I agree there's no point on PPG, 8 hours ago, Mark Morgan said: pointless exercise and does nothing At all...

Once you have done it you will never go back to landing on slow trims.. especially on normal landings (dangerous). Richard Quote Link to comment Share on other sites More sharing options...
