This is the type of paragliding video I would like to see on TH-cam. Not just a bunch of stupid films people make trying to know better and pretending to be experts after 50 flights.. Thank you very much indeed for it. It is an incredible contribution to know more about safety while paragliding!
This content is amazing please keep it coming. I love the way you have a scientific approach to most of your videos it's not just a bunch of fluff here to entertain us. Thank you Andre
Hey Andre, as a new (going to be soon) paramotorist, this video has brought to light something which is very important but so little information/ video out there. So thank you for your time to share this amazing video! As a newbie and researching all I can, this was definitely a MUST watch I feel. Many thanks again
very interesting ! One tipp from my own experience.If you ever do a SIV, check that inside the rescue boat are 2 people and that they speak your language. I nearly died at Dani Loritz SIV X dream session, cause there was only one man inside the rescue boat, speaking only spain and just a bit english, no german. My reserve was catched by the wind, pulled me over the lake, my airbag pushed me around,the result,I almost drowned. X dram flight has deleted the video immediately ....If there would ahve bee one more guy who jumbed beside me , keeping my face over water.........
Matt Wilkes, you will probably save some people's life. thanks for this study and the scientific approach. keep up the good work ! and thumbs up for Andre's great videos :)
This video can definitely be life saving - every Pilot should watch it and manufacturers should take the facts from your findings in their development - Thank You!
Matt and Andre (and others involved), Good on ya!!! I hope this study is being made available to ALL the safety and flight equipment manufacturers, instructors, and pilots that can be located. It sounds like Matt and his cohorts located several important areas for designers to improve current designs, for instructors to make part of their courses, and for pilots knowledge in prepping, practicing, and god forbid, EMPLOYING their reserves if that necessity were to arise. I'm not yet a PG pilot, but I have seen military videos addressing the use of early ejection systems, where pilots were fully trained in their use, but elected NOT to use them until it was FAR too late for them to perform. The instinct to fix the problem with the bird you are flying, be it exiting a low altitude spin, having a folded wing or chute, etc. MUST be real time dynamically situationally balanced against the WORST CASE ROCK HARD wall of final time/altitude/orientation/velocity/(whatever) that exists for the specific safety gear to function, . Sometimes that wall is the exact moment the problem first presents, depending, sometimes its worse. Safety gear, employed too late, or incorrectly, is often of little to no help. When the military finally got this thru to pilots (initial ejection systems sometimes took FIVE SECONDS to actually initiate seat thrusters in respond to the "pull", and a rapidly falling jet can go a LONG way in five seconds) fatal injuries that should NOT have occurred during flight critical aircraft malfunctions/pilot errors were greatly reduced. Yeah, try to fix it, to a point, within the safe time for safety systems you have available, but ALWAYS be aware of what that point REALLY is, for your given situation, and act accordingly, or be badly hurt or killed, it is THAT simple. Many people still try to fly aircraft that are compromised beyond "fixing" into the ground, killing themselves, where ballistic parachutes, ejection systems, personal chutes, etc. were available to the pilot at the time of the emergency, and would have saved the pilots in almost every case.
Really great work guys! Thank you! Our studies in the same subject (less scientific and perhaps slightly more anecdotal) lead to exactly the same conclusions. One additional thing we have noticed over the years is that in a rotational situation it is often best to, having cleanly extracted the reserve, "let go" rather than throw. The reason for this is that the pilot can inadvertently throw the reserve against the rotation causing the reserve to actually come back and hit the pilot. By letting go, with centrifugal force the reserve quickly travels away from the pilot and the wing and opens cleanly. In more insipid "parachutal" low G force situations a good clean sweeping throw is best.
Thanks so much - it's really good to know that people who've done as much SIV as you guys have found similar things, as it gives confidence in the findings. What you say about rotation makes total sense. I am quite conscious that in focussing purely on the actions of deployment, our set up couldn't take account of the different circumstances in which people deploy. We could only really focus on the 'getting out' part of the chain. Given the difficulty that some of our participants experienced in just doing that though, I wonder if they'd be able to think too much about the nuances of the throw when under stress? Thanks again - there is no substitute for SIV!
Don't make it too short. If it is too short, when you pull on the handle, it might pull on the reserve bag before releasing the pins, and the reserve would be stuck inside the harness.
Thanks Nico - and you are right - if too short it could pull directly on the reserve without you being able to open the container. This is another good argument for integrated and tested deployment bags I think.
Be very careful with short strops. We consistently find problems with short strops locking the reserve into the harness, particularly if the reserve moves too far away from the handle (eg small reserve underseat in a container that's too big) It can prevent or make deployment very difficult! It is important that the pins release (which opens the harness) BEFORE loading the strop. Some slack is essential. Not too long. Not too short. Having the handle not too far away (harness design) can help mitigate the long strop problem.
Excellent work on this research guys! Undoubtedly harnesses and rescue developers should give the deserved importance and consideration to this study when developing their new projects. Congratulations and thanks for the great amount of contribution to our sport! Cheers and keep on!
Excellent video, thank you! I like how you said "hit your hip, grab your reserve handle, and throw in a single sweeping action". It struck me that "HITTING the hip" should be practiced and may trigger a stronger, better, more aggressive throw. Thanks again, great data and analysis.
Great content: knowledge reduce chances of doing it wrong. Seeing where people have trouble will help us avoid mistakes being under high stress. André, Matt, you are making our joyfull sport a little bit safer. You deserve my admiration!

Thank you Andre!! Next to the fact I am a hang glider I also skydive for over 38 years. One of your conclusions to visualize is key! I visualize my skydive emergency procedures several times a week! (Had five). For more info see also: www.wimdegier.nl/sports/
This work is really great. I feel like someone needs to award Dr Matt Wilkes are very large grant to continue. Oops spoke to soon. I see this has already happened. Good job!
Haha, thanks Jumpleads! My home club, Lanarkshire and Lothian Soaring club generously funded this study, and I've also had some support from the Royal Aeronautical Society. However, I still fund most of my paragliding work myself. If anyone is feeling generous... please get in touch www.freeflightphysiology.org/support/ Thanks again!
Andre this video on throwing the reserve was awesome. I’m not a pilot but I have an idea you might pass on to Dr. Matt. I noticed the lag of the toss was due in part due to the reserve handle rope being so flexible and long. If the grab handle was more solid like a bicycle handle bar grip a person grabbing something solid could feel it easily, grab it and yank it out positively and throw the reserve with force. The soft cloth rope type handle the participants were using was like trying to sling a 5 pound weight tied to the end of a rope. Keep up the good work. I Enjoy the videos
Having done helicopter underwater escape training numerous times I can attest that knowing you are in a safe environment really eliminates the stress that would actually be experienced in a genuine emergency situation. It would be really interesting to see how these experiments could be adapted to more closely simulate the jeopardy of a reserve deployment. Great video, thank you.
Thanks Sandy. I agree. Simulating stress is quite tricky to do, while being ethical and keeping study participants safe. HUET is actually considered one of the gold standards, as lots of people do find it quite stressful. Any suggestions welcome!
@@mattwilkes2538 HUET tends to be stressful for those who are uncomfortable in water or uncomfortable using the rebreather equipment i.e. it's not the all the dunking and rolling, it's just being in a pool that stresses them out. I would consider asking non-paraglider pilots to do the exact same exercise.
@@suboptimallife That would be a really interesting approach actually, and we were thinking along similar lines for our next hypoxia study. After all - you don't need experience for reserve throws, you need to know how to do it from day 1.
I think it would be very interesting to see the strop have a bungee aspect to it, particularly on strops that are too long for the pilot. Though it would be harder to pull out, it may also help with the 'one motion' throw. Realizing that strop length probably varies based on the requirements of where the reserve fits into a particular harness, it definitely makes sense to have the shortest strop your harness can take. This is something I noticed right away in playing with my reserve deployment, and I shortened mine to barely be long enough to properly fit in my harness compartment.
This is a super fantastic video ! Thank you so much for making it and sharing it. I would love to see a study on the trade off between these current designs and that of a base rig harness where cutting away the main automatically deploys the reserve. Not sure why manufacturers have not designed auto reserve deployment into their harnesses but would love to see a study as to why it’s been avoided for so many years.
Heres a question - your suggestion is that anyone carrying a reserve should have some experience throwing it. Is there a way to do this without having to repack the reserve? I'm basically a noob and slightly apprehensive about repacking my reserve. Im ready to string myself up to something and practice, but perhaps i should fold up some old shirts throw those?
I think a lot of people have this fear, me included. But the truth is if anything we should be asfamiliar with our own reserve parachutes than even the wing really. Parachute repack courses are available in most countries and it's a great time investment you can make. We should be as confident opening and packing our parachutes as we are with our wings. Here's some more info th-cam.com/video/CFWbF6aOtss/w-d-xo.html hope it helps
I agree with Andre. Yes - it would be possible to throw a deployment bag filled with a cushion or similar, without having to repack the reserve, but as that involves disconnecting your existing system, it would be best to do it under supervision of an instructor. Are you part of a paragliding club? They usually have annual repack events
You should do a SIV course ( when you feel ready for it) and throw the reserve under instructor supervision. The instructor will teach you how to repack it. also there should be instruction on how to repack it in your reserve manual, and you maybe can find a manufacturer instruction video on youtube. To repack, its easier to be 2 or 3 people, and have a big room. Its important to experience at least one reserve deployment during SIV course, its a bit like a vaccine, you have to train your defence system, so it can react faster and be more effective next time when you will need it. It will also help to make the decision to throw the reserve when under stress, because you wouldnt have the additional stress of the unknown of the reserve.
You wanna know if your rescue opens? Then you better try it. Find a local club or pilots and make a zip line (that's what we did). For repacking there will be some experienced pilot that can help you. Or, if you do it by yourself, just try it once more: If it opens it means that you didn't do wrong and help to build up your confidence ;-)
Hello Tim, I’m interested to here more about the Timulator. Was it the practice station, the zip line trolley or both? Any guidance for building my own (I’m in the USA}
Excellent work, team! This analysis has me looking over my reserve system. Much appreciated. A question: does the natural tendency to pull and throw upwards increase the likelihood of the reserve entagling with the main wing?
Hi Bryan - while we have a tendency to pull upwards, I think we still tend to throw backwards. The chance of entanglement depends more on the configuration of your main, and the kind of emergency you are experiencing. Once the reserve is out, you can often clear an entanglement by pulling on the bridle.
@ 17:00 and your discussion of arm motion on reserve extraction the video shows several difficult, delayed underseat. reserve extractions, but doesn't address the causative effects of reserve installation in the harness container. I have found every harness with a seat board and underseat mount reserve works better if the deployment bag is installed with the lanyard for the reserve handle up. This makes the tension line across the top of the bag when the pilot pulls the handle, and is more likely to slide out from under the corner of the seat board than deployment bags installed lines up, handle attachment down. When the handle attachment is down the pilot's tension on the handle compresses the reserve against the bottom of the seat board, and tends to stick the reserve in the harness container, by forming the packed fabric against the bottom corner of the seat board. If the handle attachment is on top of the deployment bag, tension on the handle lanyard usually slides smoothly around the corner of the seat board getting the bag out without delay, or second effort as demonstrated in several of the pilots on the zip line.
fine study and massively well done and EVEN BETTER well analysed!!! and YES the POD should be directly connected to the handle and not have that 20/cm extension that will get in the way...
Would be good to see demo videos of every reserve deployment as cant seam to find any on a supair at the mo and don't think it is promoted that way and just just where to buy one..?
Excellent info. I have to be honest, the strop length from handle to de-bag has always frustrated me on both my reserves (1 front mount for H&F and 1 under-seat for my reversible harness). I'm not overly impressed with either system; certainly not compared to skydive rigs (similar to BASE cutaway systems for RAM air reserves) or even old military and sport mounted lo-po rounds in front containers, which I might add are always mounted so that the outer container moves very little upon deployment. Certainly much room for improvement within the sport wrt to adhering to a set standard to aid fast deployment.
Thanks for this, really helpful. But your work can only bring change if it is shared with manufacturers and standarisation institutions (are there any in regards to reserve systems in paragliding btw.?) Hope they will be willing to cooperate and take your research in concideration.
is the direction to throw not even too a oppotunity. I mean, in which direction you rotating down to the ground in a emmergency situation. So the solution is to throw it against the rotation for a quick opening ? I've shortened the connection leash of my rescuer's grip with a knot to get it better out and to have more power to throw it. A friend of mine have had a heavy accident with his front container. He was strong twistet and was unable to pull the rescue out, cause the twist blocked it..
(Disclaimer, I'm at 20:10 when writing this) Based on a lot of the analysis done in this video, it seems like an optimal reserve deployment system might be using what is done for skydiving reserves. Use a pull cord system and (I know skydiving reserves use spring loaded pilot chutes but ignore that) a spring loaded d-bag to launch it away from the user, probably mounted on the low backside to rear. This would prevent any user input in trying to pull the bag/handle in awkward ways leading to entanglements while keeping handle use simplistic. I would also look into using the handles that I believe are used on tandem rigs that have a harder D shape to them. It prevents being a snag hazard while remaining open and easy to get a hand into.
Amazing video with lots of useful information!!! I have a question: Is it recommended to throw the reserve in case the wind got really strong and you are blown back into the rotor with nothing but forest in the back? Take in consideration that you have a decent height, going forward is impossible even on full bar, and there are no landing options if you turn your back to the wind.
Hi Nicolae - good question, but I would not throw my reserve in those circumstances. While your wing is open, you still have control of direction (even if going backwards) and you can flare before landing. Once you are under a reserve parachute, you have no control over your descent. Thanks and best wishes, Matt
Note that ConAIR have invented a single grab handle that was ejecting the pod out in a powerful way ( compressed air cartridge) back in the 90's and I don't know why this brilliant system hasn't been generalised.... (the designers were Italian)
EXCELLENT STUDY- I would say that all reserves should have to be standardized to be pulled up. Second there should be a large D-handle positioned which sticks out parallel to the seat bottom on the pilots strong side with a semi rigid 12'-18" 3/8 diameter yellow post that the pilot can slide their hand down the post which will land them right onto the d-handle in a consistent position. Look, slide down, grab, deploy outward..........you need to develop muscle memory. Just like holstering and unholstering a gun that you never look at. Practice makes perfect and when your life is at stake you had better practice...............with the yellow post always in your peripheral there will be no random grabbing for "something", wasting precious time.
Good work, thanks for sharing :-) If this was up to peer review, I guess someone would ask for a comparison to movies of actual emergencies. For instance G forces might move a hand below the hip bone (in fighter plans you have a handle above your head in case you cannot move your hands down). Also, prayer flags are an interesting T-shirt choice for talking about safety gear :D And jet fighters for talking to glider pilots, who in many places are fighting against very generous air space restrictions for jet fighters ...
Hi Andre, nice video! I found very useful, Many times I have this question in my mind I have to throw the reserve in the side (laterally) in order to not be tangled with the main wing? Considering this , maybe than is it better to extract laterally in order to have the same direction (extraction&throw). The question is, we have enough force to use a single move to extract and throw the reserve or we need two steps? From what I saw, the problems appear when the reserve is tangled with the main wing...Maybe here is some space for safety improvement... Anyway you did an excellent movie! Nicu
Hi Nicu, many thanks for your comments. The questions of which direction and how hard to throw are an important ones. The answers to both will depend on the configuration of your wing - in particular whether or not you are falling slowly or fast, and whether or not you are rotating. I think from this study, the most important thing is just to get your reserve parachute out quickly, and then to deal with any problems that follow. I hope that helps. Best wishes, Matt
the bridle between the handle and the bag is usualy way too long and creates a big pendulum efect between the handle and bag.... i wonder if a handle directly on the bag (or a very short bridle) would avoid the pendulum efect and make for better direction/force of the through.
Matt mentioned twice that the pilots unable to deploy their parachutes within 5 seconds would've died. Was that just a slip of the tongue or were you operating under some assumptions there such as being close to the ground or catastrophic wing failure such that the descent rate would cause too much shock on the reserve? Forgive my ignorance, I haven't been flying in a number of years and I'm just trying to get back into the sport. Cheers.
@Matt Wilkes and @Andre Bandarra I managed to get this stuff published on paragliding.rocktheoutdoor.com/ which has a huge impact on french speaking paragliders. I'll get in touch when the definitive paper will be online. Cheers !

Thanks so much PPG, and for taking part in the live Q&A. I really enjoyed it.
Excellent!
I'm sure this will lead to some (good) changes in the way rescues and harnesses are built...and pilots behave
Very very good Andre...Matt Wilks
Secure base of front mount
Short lanyard
Thanks Peter - that's the one!
Awesome job on the study and very useful information.
I think it would be very interesting to see the strop have a bungee aspect to it, particularly on strops that are too long for the pilot. Though it would be harder to pull out, it may also help with the 'one motion' throw.
Realizing that strop length probably varies based on the requirements of where the reserve fits into a particular harness, it definitely makes sense to have the shortest strop your harness can take. This is something I noticed right away in playing with my reserve deployment, and I shortened mine to barely be long enough to properly fit in my harness compartment.
This is a super fantastic video ! Thank you so much for making it and sharing it. I would love to see a study on the trade off between these current designs and that of a base rig harness where cutting away the main automatically deploys the reserve. Not sure why manufacturers have not designed auto reserve deployment into their harnesses but would love to see a study as to why it’s been avoided for so many years.
Heres a question - your suggestion is that anyone carrying a reserve should have some experience throwing it. Is there a way to do this without having to repack the reserve? I'm basically a noob and slightly apprehensive about repacking my reserve. Im ready to string myself up to something and practice, but perhaps i should fold up some old shirts throw those?
I think a lot of people have this fear, me included. But the truth is if anything we should be asfamiliar with our own reserve parachutes than even the wing really. Parachute repack courses are available in most countries and it's a great time investment you can make. We should be as confident opening and packing our parachutes as we are with our wings. Here's some more info th-cam.com/video/CFWbF6aOtss/w-d-xo.html hope it helps
I agree with Andre. Yes - it would be possible to throw a deployment bag filled with a cushion or similar, without having to repack the reserve, but as that involves disconnecting your existing system, it would be best to do it under supervision of an instructor. Are you part of a paragliding club? They usually have annual repack events
You should do a SIV course ( when you feel ready for it) and throw the reserve under instructor supervision. The instructor will teach you how to repack it. also there should be instruction on how to repack it in your reserve manual, and you maybe can find a manufacturer instruction video on youtube.
To repack, its easier to be 2 or 3 people, and have a big room.
Its important to experience at least one reserve deployment during SIV course, its a bit like a vaccine, you have to train your defence system, so it can react faster and be more effective next time when you will need it.
It will also help to make the decision to throw the reserve when under stress, because you wouldnt have the additional stress of the unknown of the reserve.
You wanna know if your rescue opens? Then you better try it. Find a local club or pilots and make a zip line (that's what we did). For repacking there will be some experienced pilot that can help you. Or, if you do it by yourself, just try it once more: If it opens it means that you didn't do wrong and help to build up your confidence ;-)
This is very informative thank you...it plays a key role in which kit I buy
Thanks for the brilliant work...
...and for making my Timulator famous! ;-)
ALL HAIL THE TIMULATOR!
Hello Tim, I’m interested to here more about the Timulator. Was it the practice station, the zip line trolley or both? Any guidance for building my own (I’m in the USA}
@@jimfuhrman8665 It's the practice station. If you search for my posts on PG Forum (timbish) you'll find some pictures.
Thanks for this video - is very necessary and informative.
Thanks Tomasz
Excellent work, team! This analysis has me looking over my reserve system. Much appreciated.
A question: does the natural tendency to pull and throw upwards increase the likelihood of the reserve entagling with the main wing?
Hi Bryan - while we have a tendency to pull upwards, I think we still tend to throw backwards. The chance of entanglement depends more on the configuration of your main, and the kind of emergency you are experiencing. Once the reserve is out, you can often clear an entanglement by pulling on the bridle.
Thanks for the great video. I am going to make sure Our local group looks at the factors you bring up and do deployments at least simulated.
Thanks Keith!
@ 17:00 and your discussion of arm motion on reserve extraction the video shows several difficult, delayed underseat. reserve extractions, but doesn't address the causative effects of reserve installation in the harness container. I have found every harness with a seat board and underseat mount reserve works better if the deployment bag is installed with the lanyard for the reserve handle up. This makes the tension line across the top of the bag when the pilot pulls the handle, and is more likely to slide out from under the corner of the seat board than deployment bags installed lines up, handle attachment down. When the handle attachment is down the pilot's tension on the handle compresses the reserve against the bottom of the seat board, and tends to stick the reserve in the harness container, by forming the packed fabric against the bottom corner of the seat board. If the handle attachment is on top of the deployment bag, tension on the handle lanyard usually slides smoothly around the corner of the seat board getting the bag out without delay, or second effort as demonstrated in several of the pilots on the zip line.
This is so valuable. Thank you so much!
Great and very usefull video Andre!
fine study and massively well done and EVEN BETTER well analysed!!! and YES the POD should be directly connected to the handle and not have that 20/cm extension that will get in the way...
Would be good to see demo videos of every reserve deployment as cant seam to find any on a supair at the mo and don't think it is promoted that way and just just where to buy one..?
What a great video. Thank you guys.
Thanks JS!
Great video Thanks to all
Thanks Ronald
Damn such a good video!!!! No words. Many thanks!
Excellent info. I have to be honest, the strop length from handle to de-bag has always frustrated me on both my reserves (1 front mount for H&F and 1 under-seat for my reversible harness). I'm not overly impressed with either system; certainly not compared to skydive rigs (similar to BASE cutaway systems for RAM air reserves) or even old military and sport mounted lo-po rounds in front containers, which I might add are always mounted so that the outer container moves very little upon deployment.
Certainly much room for improvement within the sport wrt to adhering to a set standard to aid fast deployment.
Great information! Thanks so much
Thanks for this, really helpful. But your work can only bring change if it is shared with manufacturers and standarisation institutions (are there any in regards to reserve systems in paragliding btw.?) Hope they will be willing to cooperate and take your research in concideration.
is the direction to throw not even too a oppotunity. I mean, in which direction you rotating down to the ground in a emmergency situation. So the solution is to throw it against the rotation for a quick opening ?
I've shortened the connection leash of my rescuer's grip with a knot to get it better out and to have more power to throw it. A friend of mine have had a heavy accident with his front container. He was strong twistet and was unable to pull the rescue out, cause the twist blocked it..
I'm not flying yet, but I'm understanding that my reserve needs to become a part of me as well as my wing.
Amazing work! Thank you so much!
Thanks!
thanks for the research you guys! very very informative !
(Disclaimer, I'm at 20:10 when writing this) Based on a lot of the analysis done in this video, it seems like an optimal reserve deployment system might be using what is done for skydiving reserves. Use a pull cord system and (I know skydiving reserves use spring loaded pilot chutes but ignore that) a spring loaded d-bag to launch it away from the user, probably mounted on the low backside to rear. This would prevent any user input in trying to pull the bag/handle in awkward ways leading to entanglements while keeping handle use simplistic. I would also look into using the handles that I believe are used on tandem rigs that have a harder D shape to them. It prevents being a snag hazard while remaining open and easy to get a hand into.
Excellent work! Very informative! Thanks!
Thanks Evo!
Tks a lot for the quality information
Excellent video. Essential watching.
Thanks Richard
Thank you.
Loved this - thank you.
Thanks Alex!
Amazing video with lots of useful information!!!
I have a question: Is it recommended to throw the reserve in case the wind got really strong and you are blown back into the rotor with nothing but forest in the back?
Take in consideration that you have a decent height, going forward is impossible even on full bar, and there are no landing options if you turn your back to the wind.
Hi Nicolae - good question, but I would not throw my reserve in those circumstances. While your wing is open, you still have control of direction (even if going backwards) and you can flare before landing. Once you are under a reserve parachute, you have no control over your descent. Thanks and best wishes, Matt
@@mattwilkes2538 Thanks for the reply!
Very instructive video, thanks a lot !
Note that ConAIR have invented a single grab handle that was ejecting the pod out in a powerful way ( compressed air cartridge) back in the 90's and I don't know why this brilliant system hasn't been generalised.... (the designers were Italian)
Absolutely amazing content.
EXCELLENT STUDY- I would say that all reserves should have to be standardized to be pulled up. Second there should be a large D-handle positioned which sticks out parallel to the seat bottom on the pilots strong side with a semi rigid 12'-18" 3/8 diameter yellow post that the pilot can slide their hand down the post which will land them right onto the d-handle in a consistent position. Look, slide down, grab, deploy outward..........you need to develop muscle memory. Just like holstering and unholstering a gun that you never look at. Practice makes perfect and when your life is at stake you had better practice...............with the yellow post always in your peripheral there will be no random grabbing for "something", wasting precious time.
Good work, thanks for sharing :-) If this was up to peer review, I guess someone would ask for a comparison to movies of actual emergencies. For instance G forces might move a hand below the hip bone (in fighter plans you have a handle above your head in case you cannot move your hands down).
Also, prayer flags are an interesting T-shirt choice for talking about safety gear :D And jet fighters for talking to glider pilots, who in many places are fighting against very generous air space restrictions for jet fighters ...
Thank you! Happy landings :-)
Thanks Chrizzly!
Excellent!
Thanks Iain!
Hi Andre, nice video! I found very useful, Many times I have this question in my mind I have to throw the reserve in the side (laterally) in order to not be tangled with the main wing? Considering this , maybe than is it better to extract laterally in order to have the same direction (extraction&throw). The question is, we have enough force to use a single move to extract and throw the reserve or we need two steps? From what I saw, the problems appear when the reserve is tangled with the main wing...Maybe here is some space for safety improvement... Anyway you did an excellent movie! Nicu
Hi Nicu, many thanks for your comments. The questions of which direction and how hard to throw are an important ones. The answers to both will depend on the configuration of your wing - in particular whether or not you are falling slowly or fast, and whether or not you are rotating. I think from this study, the most important thing is just to get your reserve parachute out quickly, and then to deal with any problems that follow. I hope that helps. Best wishes, Matt
Thank you! Good job!
SUPAIR ACCESS 2 BUMP HARNESS has handle on hip, i used to think that was at wrong and too back, Now i know it's perfect.
the bridle between the handle and the bag is usualy way too long and creates a big pendulum efect between the handle and bag.... i wonder if a handle directly on the bag (or a very short bridle) would avoid the pendulum efect and make for better direction/force of the through.
Matt mentioned twice that the pilots unable to deploy their parachutes within 5 seconds would've died. Was that just a slip of the tongue or were you operating under some assumptions there such as being close to the ground or catastrophic wing failure such that the descent rate would cause too much shock on the reserve? Forgive my ignorance, I haven't been flying in a number of years and I'm just trying to get back into the sport. Cheers.
Sorry! Forgot to say thanks to both of you for this incredible content :D
Brilliant !
Thanks Ian!
Bravo!
Brutal! Parabéns!
obrigado amigo! :)
good video friend
Hey guys! Niice Viideo!
@Matt Wilkes and @Andre Bandarra I managed to get this stuff published on paragliding.rocktheoutdoor.com/ which has a huge impact on french speaking paragliders. I'll get in touch when the definitive paper will be online. Cheers !
Wow, your beard grows quickly 😂😂
Now I've got that out of my system I'll watch the rest of the vid!
Interesting vid - thanks to you and Matt
Tks Andre for share with us this awesome video, congrats! Hi, Gemmaaaaa!!! Ps: corrija o nome do vídeo, está "emregência" e seria "emergência". Abraço!
Thanks Gabriel!
double thumbs up!
Thanks Job!
