Wind Shear on Short Final - Glider Instantly Loses 100 Feet
HTML-код
- Опубликовано: 12 сен 2024
- This is the best example of experiencing wind shear coming in to land in my 25+ years of flying both gliders and airplanes. It was much more dramatic than it first looks in the video. It felt like the bottom just fell out from under the wings of the aircraft and luckily my instinct and training told me to push forward on the stick and not back to try to salvage the airspeed. Notice how losing that 100 feet instantly still kept the same airspeed. In a normal situation, 100 feet of altitude would equal an additional 20 knots of airspeed. The winds were blowing down the runway at about 20-25 knots at altitude. Once I got closer to the ground the wind instantly vanished leaving me close to stall speed had I not pushed the nose down. Its pretty difficult to do when the ground is so close, but it worked. This is an ASW27B high performance glider / sailplane and the airport was in Hobbs, New Mexico. Thanks for your comments and for watching! Bruno - B4
"Well that was some sink."
Calm as a fighter pilot haha
I think this looked like sink, not shear, as his immediate reaction indicated. Shear would manifest as a change in airspeed followed by a change in altitude. This was just a change in altitude without the loss of airspeed. He was right not to pull to try to retain altitude but that is to avoid losing airspeed in the sink, not to gain it back from the loss of a head wind.
@@ljfinger There was a strong indication of horizontal directional/speed shear on that yaw string exactly at the moment he sank. Just an observation as I suppose sink could also be cause for a flicker in the yaw string. Seemed to fast to have been control induced.
I shit my pants just watching that
Like water off a ducks back. That was some shit hot flying.
It didn't look as scary as I'd expected from the description but the very short final was a bit low indeed;) Thank you for the great video - brings back some nice memories!😉👍
I was so confused about what runway he was aiming for. 🤪
fr I was like what the hell type of approach is this
The fact that he points the stick forward to increase speed to not stall is professional stuff. Even tho he got close to the ground, physics was first on his mind
was that the beeping sound? low airspeed warning?
@UC2C3ar0KtlHvEUKZvMmFzZA I love you 💘 stay positive. Your okay 👌
@@comfortableovertones Thanks for the insight! That's what I suspected.. pushing the nose down this close to the ground must be so difficult to learn. I think instincts can be deadly in such moments, and that's where training pays off
@@larsfroelich Actually he got the right instinct of pushing forward on the stick.
looked to me like he pulled back.....hard to tell with all the stick jiggle i guess
Hey Bruno, in April I told you that your videos made me pick up glider flying again after 20 years of inactivity (I am 39 now) because your videos inspired me to do so. I am happy to share with you that today I passed my final practical exam and I am now a fresh SPL licensed pilot. Thank you so much for guiding me back into soaring!
That is huge news!!! Congrats on the achievement today and I hope you have many years to come with lots of fun and safe soaring. Thanks for sharing!
Awesome!!! same thing happened to me in 2015 thanks to Bruno
Congratulations!
Congrats!😀👍
Thanks for the inspiration. I'm 41 now and begin to miss flying like crazy. I know there's a natural gap of (glider) pilots between the ages of 25 and 40, but I think it's time for us
oldies to return to get airborne again :-p
This reminds me of the first trauma call I had as a new EMT in Arkansas almost 15 years ago, call was for 'someone flying remote control plane broke their ankles(??)' But when we got out there saw a glider had nosedived about 200 feet into a bean field adjacent to a grass agri airport. The pilot was an older gentleman (60ish) and had badly fractured both ankles and knocked his head hard, but craft did not flip or spin..just buried the nose and a 15-20ft dirt trench. He was in extreme pain as we pulled him out and about 200meters out of the field to our ambulance, but all he said was he was preparing for the final j-turn to land and 'felt like he just stalled out of nowhere'. One interesting thing he said was "they says when you know you are about to die your life flashes before your eyes...well, only though I had was 'oh shit, you've really gone an messed up good this time'". Once at hospital they stabilized him and flew him out in a helicopter to a regional center for surgery.
I urge all sailplane pilots to practice quickly closing the spoilers/dive-brakes and getting the nose down so it is instinctual. Go up with an instructor and practice stalls with the dive brakes deployed. Your reaction should be to close the dive brakes immediately, nose down immediately, and get those wings flying well again. The instinctual reaction could save your life. Also, pilots need to proactively anticipate the wind shear/decrease affecting your airspeed on landing approach when the wind is over 15-20 knots aloft. In situations like this, carry an extra 5 or 10 knots (or even more, depending on the wind conditions and potential for turbulence on final).
Todd Hahn i agree because Indont understand but you sound genuine and smart
Thanks for the info
@@mamindhive Todd Hahn really does know what he talking about.
Obviously practiced these maneuvers every night at bedtime, lol.
I've got 40,000 hours on the simulator.
👧
I’m glad that ended well for you!
You handled that like a real pro!
Wow!! Thank you for this scary ride, wich is a good lesson. I never saw it happen, and don´t wanna see again! I also thanks for showing this beautiful runway, place of a world championships in 1983.
Legal encontrar o senhor aqui, Professor!
@@bruno5016 hehehe, o RUclips é um mundo pequeno. Eu sou piloto também, só que meu aeroclube está parado. Quando voltarmos a voar, vou fazer vídeos em vôo. O vôo em planador é cheio de matemática!
hi Bruno. I plotted airspeed and altitude from 0:50 to 1:50 and looked also at hte joystick position and the yaw string. I saw a very stable airspeed around 62 to 64 kt, with the exception of a short increase to 70 around 1:30. Nothing that could have sent you down in this frightening final. The yaw string shows that there was turbulence at low altitude and I believe in a short and rather violent movement of air with a strong sinking component during the last 100ft above the ground. Let me congratulate you for the way you kept everything safe in this dangerous final minute. And thank you for your sincere and open videos. Go on. I'm one of your fans.
Thanks so much for taking the time to examine this footage so closely. It all happened so quickly in real life. Glad there was enough room to recover. Thanks for watching and for commenting!
Well that was a bit of a shock when that close to the ground.
I had the same thing happen to me while instructing in a blanik L-13. Student kept pulling back on the stick and I kept pushing forward saying speed speed speed....and the bottom fell out. My airplane, I pushed the stick over and dove it. I leveled out at the ground and flew the rest of the way in ground effect. We barely made. Good video Bruno, and even on video I saw the drop.
The instinct I developed many years ago is that the most efficient thing is to close the brakes immediately, and that makes the glider gain a lot of lift. I always made sure to calculate my glideslope on final with full or almost full open brakes, which gave a lot of margin for things like this.
If the airfield is short, you better use half-brakes approximations, as you could encounter a thermal on final approaching
@@Quemedices684 , I agree, we are all taught half airbrake on final. Wind shear nose down and close airbrakes, use ground effect to extend glide if caught short. If over shooting, full airbrake and sideslip to hit the spot. What Bruno did was perfect and looked instinctive. This all happens without thinking for me, when I started instructing it made me revisit all my flying and honed my skills even further.
Oh, that lovely "just flown into a vacuum" feeling!
It looked more like this dude was playing with his joystick 🕹
Hahahahahahahaha
I wonder if they ever play the skin flute up there
Lol
1:35
Hahahah
Thanks :D
doing the lords work
@@bozemanbillbill1790 bro it’s a minute and thirty seconds lol
I've had that experience. Brain said "Oh S..." while training took over.. Scary moment..
SPF (Sphincter Puckering Factor): Moderate - High
Hello, Bruno. Nice save with what you had to work with which wasn't much in the way of altitude, airspeed, and position to your intended landing spot. A lot of things rapidly deteriorated around you, all within a blink of an eye, making for a potential accident, not of your making. Thanks for sharing this rare event (for me) that we can't recreate nor train for. You moved this peril from the recesses in the back of my mind to somewhere closer to my conscious thought when landing. Knowing vs. reacting aren't the same thing.
This is true, you can't train for this in actual flying. Just drumming the stick forward idea into your head and (what is the word/s) virtual rehearsing of the maneuver in your mind.
@@csleclerc57 You are right and so true about training and preparing. A "stick forward" response has to be slower due to the inability to train for this type of condition and being so close to the ground. A lose lose, while hoping for the best, situation. I'm not looking forward to this kind of encounter since I have the additional workload of spoilers and flaps to deal with while in landing mode. So far, I've been lucky.
I knew I recognized that old Army Air Corps runway. The wind out at Hobbs can get a little funny during the day, especially in gliders. Outstanding work!
Gnarly. Thanks for sharing Bruno. I watched at least a dozen times. Glad it turned out fine.
I'm not a pilot but I have a huge appreciation for the skill and discipline required to perform this maneuver. Responding to the threat of a stall by diving or at least not pulling up is counterintuitive at a very basic level. Like with scuba diving, these vital counterintuitive moves have to be constantly practiced. It seems like in a high-performance glider like this it is actually hard to land and stay landed if your airspeed is too high. I don't have to be a pilot to understand that sinking air has to turn into horizontal shear well before ground level since wind cannot blow through solid objects. To see how easily Bruno can avoid landing given even some extra airspeed, look at his video on the air show.
I'm glad you are OK, Bruno. I like your beautiful videos of the mountains and sky and the narrative.
Hey Bruno.
Thank you for your videos. I last flew 10 years ago. I have 17 hours on my logbook. I am 63 years old and you have motivated me. I am going to go up again this Wednesday February 3rd, 2021
Thank you for the inspiration
Nice! Please make sure to report back how your first flight goes. I'm really excited for you! Have fun and be safe. Bruno
I am not flying sailplanes any longer. Maybe paragliders and paramotors next? However...was thinking back, if this happened to me would I have put the stick forward? I remember the mantra was when in sink... "stick forward" to get out of it as soon as possible and find lift. Furthermore, when a stall is threatening it is of course also stick forward. But when you are this close to the ground, perhaps ones instinct to pull back would be "checked" from the experience of always pushing forward in sinky air when flying normally at altitude. A newbie pilot might be less inclined to react properly? With only 130 hours flight time over 6 years I had never encountered a situation like this one. Notice he also pushed forward on the airbrakes as not to exasperate the situation. Great pilot Bruno, keep up the good work, been watching you since the Phoebe days.
I was watching the "Yaw" string and at one point was almost flowing 90 degrees left off center. If you lost 100 feet I am glad you were at least 150 feet. Delta Airlines some time ago lost an L1011 off the end of the runway at DFW due to Micro burst. It literally slammed the aircraft into the ground. I was working for American Airlines at the time and would fly into DFW to go to HQ. Its a little unsettling when you think about it, so i just never thought about it. I always enjoyed flying (passenger, i'm not a pilot) and would love to fly again. Lousy TSA has ruined it for me so I won't fly (commercially) anymore. Glad you are ok Bruno, your the only glider pilot I know so fly safe so I can continue to watch your videos.
Definitely was some time ago
Yes that is the reason that even though a glider stalls at say 32 mph in a 2-33 most safe glider guiders fly the 2-33 at 60 mph or even more in very turbulent condition during the landing pattern and especially on turn final. You do not have a engine to fire wall . I notice many power pilots decouple from that needed measure of adding lots of airspeed for landing since they are used to dragging there piper cub around the pattern by the prop and dropping it in totally owning the entire landing with the engine power .
You might consider writing a book, Good Sir. Your soaring is inspirational, educational, and just downright cool :-)
Same thing happened to me when i was 16 yrs old...44 now. On final. Glider hit hard flapping the wings like a bird...my head and neck pushed down with such force it has caused back issues even today, permanent bend in my neck bones, couple neck bones fused together and one leg slightly longer than other...but the glider was fine.
Well boss, maybe it's a good thing you were 16. I notice now at my age of 30, things aren't where they used to be. I can be driving down the road and hit a bump. With that tiny bit of lift, come crashing down on my nutsack.
If I were to have your experience now.. Yeesh, might declare an emergency from the ground.
Had Wind-Shear once (late 1990's) on Landing a glider, 6,000 foot strip, 300 foot wide surrounded by trees. Perfect approach, on speed & altitude, air brakes cracked and boom there it is! Closed the air brakes, lowered the nose & still hit Terra-Firma, bounced but landed safely with no damage. I miss flying so much!
Keep on flying such low finals and aiming for the start of the runway and you might not walk out of the next one...
Sailplanes are in a different universe of performance compared to what I am used to. What a slick ship.
Thank god for ground effect
I love gliders and your flights are great.
A modern glider, especially a non flapped one, has an awesome ground effect (they can stay in it for miles without losing much speed). Therefore, what seems scary for motorized plane pilots (pushing the nose down, even if it means approaching the ground), is actually the safest nice in a glider in this situation, especially if the speed is low, as long as there are no obstacles in the way. So yeah, we can't escape sinks with an engine, but have other tricks up or sleeves ;) .
That was alittle scarry Bruno. It looked like you were being pushed to the ground glad you made it god bless. Dwight
I'm a PPL/INST transition pilot and was close to soloing my glider (have done so already and preparing for my checkride), I was on the controls, also on base to final and the same exact thing happened. My left wing dropped like the air had been removed. Wind was also 20-30kts at pattern altitude and about 10kts at the ground. My instructor took control immediately, lowered the nose quite significantly to regain airspeed and we landed safely but passing the treetops a little closer than we would have liked. I had never experienced wind shear before and it was the scariest experience in my time flying including powered aircraft. I have been scared ever since of making that turn from base to final at our airfield, even though I have flown it many times after that event. Im just happy we got to walk away from these.
I had a vortex / downburst encounter at 300' losing 285'. A 28 kt shear really messes up your approach. Yes, it really feels like somebody has yanked the rug out from under you.
Sudden Silence - Stick Forward!
My Oudie coupled to my Air Glide S records at 1 Hz including GPS, TAS and GS. Bruno's flight computer may be recording similar data.
Exactly the opposite of my check ride, so long ago. After a 3 hour oral exam (yeah, this designated examiner was way beyond tough), then the 'trick question' at the glider about step by step disassembling a 2-33 (which was used to FAIL 2 people I know by this examiner) and pulling out a cheat sheet I had meticulously prepared, she relented and off to the flying exam. I rejected the tow line after inspection as it was frayed underneath (close to failure), the examiner was embarrassed as the line crew worked for her, and after fixing off we went. Good exam flight, but turning base HUGE lift and I was 200' too high in a couple seconds, needing to hit precise cones, so already used to putting gliders into short spaces, slipped the shit out of the glider and placed it on target smoothly. Examiner didn't have words other than, "Really nice, you are a pilot now".
What a great story! Thanks so much for sharing. Glad you were prepared. Sounded like the check ride examiner from hell.
Don't you just hate it when that happens. Glad you kept cool about it made it safe :-)
I pooed a little bit just watching.
Not even the expected ground effect was there.
Wonderful to see a pilot that doesn't just pull up and knows it's going to lose height and rides it down.
Ground effect has to be there somewhere if you wait for it.
The panic in the pilot's voice ... the panemonium in the cockpit....
I just typed a lengthy screed of how when watching this I'm barking out all your mistakes, but then deleted them all to say, I'm glad you landed safely. good job.
It happened in my club, with a friend flying. He closed the spoilers immediately, but it was 100% instinct.
It was a bit hard to see when the sink happened. What time on the video was the worst of it? Things I noticed: You've got the airbrake open most of it? How come you're so low turning onto finals? looks like 200 feet? Or is that after the drop? Also at 1:25 the brake starts creeping open? If you hit heavy sink why didn't you put the brake away? I'm not at expert at the 27B, only flown a 29 for a couple of weeks, but the whole circuit looked very shallow?
Turned downwind to base at 700' and base to final at 400'. It was a lot higher pattern than it looks I guess.
@@BrunoVassel Yeah 400' sounds fine to be *on* finals, except in this case the turn onto finals started at 400' and ended 200' agl? Which makes sense you'd loose that much as the brakes were open around the turn. What really matters though is the angle to your aiming point, so 200' is fine if you're close in! Still looked too low to me. But yes it is very hard to tell from wide angle video.
I would imagine strong thermals near the runway could also produce sink. Is this more of an issue when glider airports are in desert area of the country rather then grassy type runways in the midwest. I'm in Arizona took a glider flight last may it was about 105F out we hit a few thermals that were so strong bounced up out of the seat my head touched the canopy not hard it was a wild ride. Really got me hooked on gliders. The glider port here in Phoenix is about an hour drive not really that easy to use.
Wow that was a fast drop! Great awareness
Nice flying... adequate airspeed saves the day again. I did a winch launch in a K7 once and was continually modifying the entire circuit in killer sink. The CFI drilled me when I landed for flying low... I actually think I did really well because you had to be in it to believe it.
MCAS: ACTIVATED
Had a heavy wind shear today, anticipated it already so was flying +30 kph above approach speed but still caught by the wind shear. Made a nasty bounce as it was close above the ground. The first time I really was scared in a glider, the feeling that you become a passenger of your own plane was really scary.
I had that happen landing the club 1-34 over the river this summer. Close spoiler, nose down a bit to get more speed to get the rest of the way across the water, cleared the road at the base of the runway, but still had too much sink rate to avoid a hard bounce at the threshold. Glad I'd made new cushions from energy dampening foam and was trying them out. It probably saved my spine. It bounced 15' back into the air. Elevator movement was constrained as the elevator was damaged (very scary!). As every pilot knows ... no matter what happens, don't forget to fly the plane. The second landing further down the field was ok. $15k damage and hope to have the glider back next season.
I came in too low and took away an option. Pilot error.
... and I feel very humbled.
Dave Villeneuve yikes Dave! Thanks for sharing your experience and I’m so glad you ended up ok. That’s a lot of repair work for 1-34! We learn from the mistakes and lessons that we are lucky enough to live through. Take care and hope you can get back up into the air soon.
@@BrunoVassel Thanks Bruno. It was a club glider, and fortunately the club has others, so I've kept flying. I flew a couple flights with an instructor after that, just to make sure I wasn't psychologically impaired while flying on final over the river. In the meantime I've been flying an ASK-21, Grob 103, and got to fly a Libelle 201 once.
Yah, the cost for the 1-34 is exacerbated by all the manual labor around removing and then replacing hand-cut and unique aluminum sheeting around the tail cone. I'm glad it can be fixed as while it is not a stellar performer, it's a fun little glider to putter around the local area, and thermals well. It's also good to preserve these USA manufactured birds created back when there was domestic production of gliders.
Your ASW-27 is a beautiful machine. I've helped rig/de-rig these and am amazed how light and easy it is to install the wing. It's well outside my price range my friend.
Happy landings!
This is why I wear adult diapers when flying.
yep and brown pants. always wear those :-)
You have a long runway ahead yet you choose to approach low and slow. Yes, I know all gliders do this but for a powered aircraft in a (power off) glide approach, one aims to land well inside the field and then add flap to bring forward the touchdown point.
Agreed - in a power plane that just lost an engine, I would be aiming for about 1/3 down the runway to touch down. Plenty of buffer room in all directions. In landing a glider at an organized contest where I have other gliders right behind me in the pattern, I chose to land at the end of the runway and roll up to my trailer/tie down. The speed flown was not slow but right on for the conditions of the day. This ship normally flies the pattern at 55 knots indicated. I added 10 knots this time due to 20 knot winds. So not slow but yes low.
@@BrunoVassel Ok, you had a 10kt margin which came in handy - whew! Great videos, I enjoy them all, stay safe, my friend!
Mad respect for glider pilots! I kinda wanna try it as I get old and crippled from aggressive sport injuries.
I hit wind shear once while landing a paraglider. Went from about 300' to the deck in about 4 seconds. My ankle still hurts.
Good you had sufficient air speed! Nice landing.
Sink rate! Don't sink! 😅 Excellent aviating, thanks for the share.
I thought you were going to need darker shorts, but wow did you take it in stride!
Already a low altitude approach, then add some wind shear and you are bound land short. I can understand it if the strip was tiny but this one looked capable of receiving the space shuttle.
That's instinct. Nice video :)
"Well that was some sink"
*Changes underwear*
Good on you for not freaking out. Great glider control. Que Deus te abençoe mano
Valid lesson in reacting the right way in a crisis...
However my gut instinct from the start was you seemed to low and wide for my comfort zone..... but I'm only an old intermediate ex- weekenderer..
From the moment the glider turned on to finals, the aiming point of runway threshold was marginal. Preferable to have a larger margin of altitude, half brake approach which can be closed to counteract unexpected sink.There is a 6 foot maize crop on the undershoot of my local strip!
Same goes for light aircraft - if there are obstacles, plan for an overshoot and then use full flaps or side-slip to make certain of landing in the field.
Seems to me more like a hefty sink or microburst type event than pure windshear. Airspeed did not seem to change much during the sudden sink . You handled the situation very well!
Agreed. I zoomed in on the ASI. But certainly abrupt.
WINSHEAR AHEAD!
WINDSHEAR!
WINDSHEAR!
WINDSHEAR!
That looked scary, I would have yanked the stick right to my stomach in fright. :)
Thanks for sharing, enjoyable as always.
... and that had killed you.
@@Claude-Eckel yes, I am not an experienced glider pilot :)
Your videos are so cool glad I found this channel
You've done that before, haven't you? LOL
Lucky you had so much concrete undershoot to play with.
This pilot has some skills!
I would always suggest to do the approach as high as possible. I always try to organize my landings in order to touch down on the threshold if the spoilers are fully engaged all final. This way you have all reserves you can get.
Respectfully disagree. One third to half spoiler gives you a margin both ways - lift or sink.
@@lautoka63 Yeah, the full airbrake approach is great when you want to clear a fence and have a kilometre of runway in front of you. NOT a good habit to get into, when you're outlanding in a tiny field and realise you are overshooting with full brakes.
As well as putting the nose down I think you should have immediately put the airbrakes fully away instead of just a little jiggle in and out.
John Galloway i agree even though i dont understand
I agree because it is 2019 and everybody must have an opinion or else!
DreamsIntoReality what is there to not understand?
yammmit nothing
Wow. My instinct (with no experience at all) would have been to pull back.
risraelsen, the last thing you wanna do.
He did. 1:35 he pulled the stick back and right.
He had enough speed after the dive to pitch up when he pulled the stick though.
@@robertm8401 the condition ceased plus ground effect I'd say.
Off course you can pull back gently if you have got lots of excess speed. Generally though, you should keep a steady hand when flying this low.
"Well that was some sink" he says. Lmao! I might have pinched a poo on that one! XD
Absolutely awesome but even though you totally could have died you have response is "well that was some sink"
Is that Hobbs New Mexico, seems like it. Old pilots don't die, they just fade away.... ASWC, N6514M, GN.
It seems a good idea to approach a bit fast in a glider cos the windspeed difference is a real issue without an engine to thrash.
hard to even tell if you meant to do that, thats insane amount of ground effect after what seems to look like touch down
Do yourself a favor, and check your ASI. It seems like on the roll-out that it was moving down in jerks almost like it was sticking. Also, I'd love to analyze the IGC file. If you posted it on OLC, can you tell me the date of flight? I don't doubt your recollection of the wind speed differences, but it looked more like a pocket of sink, more than wind sheer. I would expect with wind sheer to see your ASI drop, then recover. Unless it was sticking, and so it didn't register the drop. As always, thanks for posting this.
Nicely done! Now I feel bad for complaining about the lift I always manage to find on my crosswind and final . . .
The sight picture base to final seemed low well before the sink took hold?
Cary Kennedy agree. I was just going to comment that I don’t see a radical sink that would change things significantly, he looked like he flew it in low to me. Maybe lost some height at the end, but hard to know how much from wind vs bank. Regardless-if he had a safety net coming in he could have absorbed whatever drop that was without ditching
Reminds me of a approach into Truckee, California many years ago. Except there is a hillside at the threshold. That extra 5 knots paid off.
What's that humming noise?
Sorry I don't know much about gliders 😶
Impressive and scary, especially after watching that sink a few times. Do you have tips for training that 'nose down' reaction in this situation? I'm a student glider pilot myself, and I figure the odds I'll run into this situation while there is still an instructor sitting behind me are pretty low.
Good thing he had his broen trousers on 😁
You handled it pretty well.. Love from india❤️
Yeah, just keep the airbrakes open! 😂🤣😂
Funniest thing I notice looked like he was using his rod pretty good!
holy shit that scared me....no wonder friend of mine is putting a small turbine on his glider lol
happened to me once in libelle, finished up doing an undershoot procedure that was taught then, like you ,nose down, trouble was I was in the field before the glider field, so had to hop the fence, hmmm, turned out ok, but my CFI was not impressed, you handled that well my friend :)
With respect to your CFI it sounds as though you handled it well, especially in a Libelle which is unforgiving of any variation in conditions on the approach.
@@richarddavis7778 yes indeed, thank you :)
I fail to see the part where he instantly dropped 100 feet?
1:35, but looks more like 10 feet :))))
? 100 ft is only 30m or so which looks about right
Jamalien N what do you mean?
@@DanSlotea Watch the altimeter.. it is actually about 100 feet.
You are very professional! Bravo! 👏👏👏
@Fester Blats tes but as one flies in the same dangerous environment as professional pilots, we need to act in a professional way if we want to become old pilots.
Man that was nicely done beautiful
Hi Bruno, don't take this the wrong way, I would like you to stay safe and being able to keep continuing sharing these kinds of videos. However, I couldn't help but think of a discussion we had a couple years back (don't remember which video). The discussion was about the usage of speed brakes in the turns of the pattern, especially on the turn to final. I noticed that you kept on using speed brakes again now, also on final. I noticed that when you left the turn for final, there were some interesting noises. Your glider alters the flow field around you but also the other way around, the flow field that you left behind has an effect on your glider as well. Now, I am not saying that the speed brakes are the cause for that sudden drop but I feel like it did contribute to it. It's all about that Swiss cheese model right? we don't want the holes to line up and I feel like the speed brakes usage was one of those holes.
Like I said, it is not criticism, it is also not me trying to prove that I am right, I just want you to be safe.
Howdy! Good to hear from you. This video was recorded in 2013 well before our speed brake conversation. :) Cheers!
Super video and learning / teaching experience.
For this reason, and others, the landing check ' straps '.. means straps TIGHT. Very tight. Might just save your back. Along with the dynafoam.
Things happen fast on short finals. Been there, done that. Got away with it!
What we get taught from the beginning during landings: speed is your life. With some crosswind for example, our short final is very bumpy and can get you into the same sink as in your video. We land with +20/30 km/h depending on the amount of crosswind and never hit the trees. Some ULMs get surprised when landing on our airfield when they come in low between the trees and get hit by sink.
Nice recovery Sir!
Wow. Good job Bruno!
That looks like soo much fun
Was this "sink" or "shear". "Sink" is a DOWNward movement of air (right?), and "shear" is change in a (normally) horizontal direction/speed. ?? Maybe this is just semantics.
