Puchacz (pl.wikipedia.org/wiki/Puchacz) is a big owl species with wingspan up to 1,8 meters.

First: They had their airbrakes in at least when they filmed straight ahead after pulling up. Could see the lever being fully forward…

@@zaenith At 0:34 during pull up you can also see the clean wing.

"should be 'Poo-Hatch'" Does not sound nicer. 😄

If you've ever flown a puchacz, you would also know thats it's imposible to go VNE or even close to VNE, in level flight, with the airbrakes out. Even in the ground effect. Those airbrakes creates an enormous amount of drag.

He didn't kill you this day .

I had some great days gliding with the air cadets back in the day. I was at central flying school, and the Air Marshall (2 star general eq) for the school showed up and asked for a go. They were his gliders anyway, so as I was already taking up slack, he had to wait as I had the last cable. Anyways 10 minutes later the guy was in the air, and he did a steep approach and then 2 loops on final. I remember a couple other instructors grumbling how it wasn't fair "We're not allowed to do that, or we lose our ticket..." True story, back in summer 2000.

I had a few training flights in a Bocian but never knew it meant Storch - I thought it was Butter 🙄 I LOVE the pronounciation and meaning of Puchacz 'though - Cue even worse puns about 'Does being an Owl confirm an automatic Night rating'?

@@Farweasel Yes, and flying in NIetoperz (the Bat) gives you IFR. BTW, Butter is Maslo (say mas-woh). Bocian is white storch. And Jantar is Amber

Agreed. This is pretty standard behavior for Poles... lol

SZD-51, I loved flying that thing. the seat was crap but the aircraft unbeatable (at our club anyway) on days with small weak thermals.. It felt like the earth was just repelling that thing (when not flying fast). But it can drop like a brick if you want it to 😁

@@esenel92 great for flying in cloudless thermals

True. At 0:38 you can clearly hear reopening of the breaks

@@gliderfan6196 not so loud if opened up the top of the climb like it was when the camera panned to the wings again.

@@FinalGlideAusyou just comment for human interaction don’t you? You have said nothing of substance.. nobody cares what you highly doubt you’re not the main character. 😂😂

@@jmax8692 Sorry, I don’t argue with bots…

Your doubts don't matter here, it's SZD-50

Came here to mention the same thing: very likely closed at this point, by the position of the blue airbrake handle at 2:01 and 2:19.

@@uhertlein Not sure about the handle, but around 0:33 you can see much larger portion of the wing than at 0:51 and the brakes are simply not there during the turn after the climb out.

I agree regarding the brakes being shut through the low pass and pull up. The airbrake handle is a good indicator of that 🙂

I agree You can see that short before "base" the Vario is on 0 od -1

One man's recklessness is another man's quest for discovery I dare say. The timid may die of hunger and the bold may die eating a toxic whatever and somewhere in the middle is the sweet spot, who's to say where that is exactly.

@@hotprop92 the one who puts others at risk. the end.

Indeed. Well, stupid is as stupid does. And especially the second one was one of them

I believe the phrase sought may be 'added challenge and excitement'? And YES I do want to try that (&) I AM dumb enough to do so if some kind, misguided soul will lend me a Puchacz

@@Farweasel may the odds be ever in your favour.

Definitely not moving haha

Yeah, I did that to 500 ft above circuit height over Omarama in a Club Libelle after an 18000 ft wave flight. I recall 85 knots on the dial on the way down -- only just above the 81 knots rough air / maneuver speeds. When I was a raw student an instructor demonstrated similar in a Blanik from 12500 ft. I recall about 120 knots in that one.

I agree the thicker-warmer bit. In the 90's I had a share in a Brazov IS 30 we were up at 18000' and my P2 complained of being lightheaded. Popped the brakes, like the Puchaz, top and bottom paddles, and stood it on her nose. I always remember the sensation of the air 'thickening' and getting warmer

@@robert100xxcan seem to feel the the inversion layer / 5:55 temp change too I've noticed in the climb. Get that 5 to 10 degree drop when the thermal lift tops out.

Yep, completely right. I managed to dive negative, so you see the ground approaching, but also shifting up in the canopy. It is just like a free fall skydive, 170 km/h straight down. Take an easy pull out, and close the brakes not before normal attitude...this will give an astonishing speed built-up.

Hey awesome stuff, and good luck with your Paragliding!

@@PureGlide I like to ask a question from someone that appears interested in thinking about the subject for their own benefit and telling others and I have to say you're a gemstone in this tired old world of people that want to keep every secret. According to my calculations if I could clone you and put you in two gliders that were clones, at the top of the weight limit and one at the bottom of the weight limit range. My calculations predict.: the heavy glider will have the same glide ratio in straight flight except it's going to fly faster. However when that guy in that heavy glider is coming to catch the guy in the light lighter and he wants to get away from him it's not that hard. Turn all you can do in that light glider is turn and turn and turn. Whenever that heavy glider turns he flies fast and he drops altitude faster and he has a bad glide ratio compared to that light glider. The tighter you turn the more altitude you lose from that weight. Is this true to a point of being observable for a guy like you that can actually see something not a guy like me that can't hasn't looked at enough? The second question comes to mind the overloaded airplane. iWatch airline pilots that are respected for their understanding of an airplane take off flying in a straight line in an overloaded general aviation. When they get taken off and finally climb up out of the airport they turn a little bit and the plane dives into the ground. According to my calculations there are a lot of nonlinearities that all are going bad faster and faster when an airplane flies overloaded in the curve. If you draw a chart with minimum radius and minimum air speed, when you turn you will fine below the minimum radius the airplane will dive in the hole that it is turning towards. When you show the glider slipping and losing altitude he was a long ways above the minimum speed and a long ways above the minimum radius of curvature, for that weight. That's why he had plenty of extra control authority to get out of the slip. I saw a fellow flying a heavy bomber and he did like a "parachutaul stall". He said that while you had the control authority before you stalled and you were moving and could steer you needed to get the nose to start coming down because after you stall you're going to fall a long ways before your nose gets pointed to where you have any control authority. I have not done much looking at this problem with extra weight. So have you noticed a difference in your gliding results and distances when you turn tighter and when you turn wider? When the paraglider lands they go into a sharp turn and drop some altitude on both edges of the field running back and forth and then when they get to the right altitude they cut a 90° turn into the wind and no more turning. I don't think regular gliders do this often. Thank you for showing me one guy that was doing that. I don't have much money so saving up money to go on a glider ride is pretty special event.if I knew somebody was going to take me up in a glider like that and just fly back and forth over the field swooping up and down I could miss some feed you know I don't need new socks I can just make some out of this old shirt because I wanted to go on that ride when I saw it.

lol so true

Check out Inönü/Eskişehir airfield (where that accident happened) on google maps. It matches the video. Makes you wonder if it also was the same pilot.

@@akcrazy1983 Definately Inönü/Eskişehir airfield. According to a Wiki page, one of the pilots was Metin Özbey, a CFI affiliated to the İnönü Training Center of the Turkish Aeronautical Association. He also represented Turkey in the World gliding championships. The other pilot was Semih Uzunlar, also an instructor. Information is sketchy but it was reported as a landing accident.

I believe the news reported the wrong glider registration. Metin Özbey and Semih Uzunlar, unfortunately, passed away when TC-PFP crashed, but the news reported it as TC-PFE.

​@@1992jamo TC-PFP is a Ventus in the Turkish Aeronautical Association inventory. We lost them when TC-PFE crashed on 29 June 2011. The pilot in this video is my dear instructor, Metin Özbey, and the video was recorded by a passenger, a Czech paraglider pilot visiting İnönü, Turkey.

@@smykgoksel I am really sorry to hear that.

Hi definitely there for the first video, check again, look for "Original video of first clip:" I don't know if the second one is online.

@@PureGlide many thanks! I don't know why I didn't find the link in the first place, despite checking it a couple times.

Rules in NZ for a solo pilot are spinning down to 1000 feet, unless you're performing for an airshow with ratings, then it's 200 feet. So this was slightly lower than allowed. It was over an airfield in controlled airspace, not sure I'd define an airfield as a populated area? There probably is a definition somewhere... anyway so it wasn't TOO bad, but still not great

Good point! yeah shouldn't have said fully aerobatic, but more aerobatic than many gliders, in that it can fly inverted. Cheers

Someone in the comments mentioned that with the A/B extended VNE is not attainable in a dive?

@@hotprop92 That is very true! We do something we call `dive landings`. We start to descend from 200m right at the beginning of the landing strip, with full AB, and we dive at 90 degrees, followed by flaring and landing. We do not do it if there is a lot of traffic, and we announce it by radio, of course. As for the split S, one can use the AB, but then is not a clean maneuver and in a contest it does not count. For that matter I prefer the snap roll, followed by half loop, but it is not a split S.

He didn't, I added a correction in the description :)

I'll have to try it! I've never felt anything close to a wing stall/spin going into sideslips, although I'm sure it's possible :)

Sure if you switch in an uncoordinated fashion. You'll always be able to kick opposite rudder faster than roll that wingspan over to the other side. Kick top rudder in a tight turn and you'll do a snap roll entry into a spin, and away we go.

Haha yes I have since learned ! It looked so real in the video

It turns out the other aircraft in the video was on a pole :)

@@PureGlide so they are on comms with tower saying " we also greet from cockpit".

It’s in the manual for each glider, typical limits from memory would be 5-6g positive, Less negative? Aerobatic gliders typically higher

Puchacz in that video g limits: +5.3 -2.65 from Wikipedia

@@PureGlide That's pretty impressive.

Whatever, like Stall Turn/Hammerhead turn/Feisler etc horses for courses.🙃

Yeah I know :) I just forget after years of saying it wrong!

No the blue, red is to detach the canopy

It's probably because of airflow in the spin and pressure sensors like in side slip the speed is also going down on indicator - correct me if I'm wrong? :)

I always wondered what the little window on the side of the canopy was for!

oh yeah I do know that, I tend to use it wrong all the time anyway

@@PureGlide Don't worry. Poland is just a four hour car ride from my hometown. Once over the ( thanks to EU invisible) border you are in a completely different "language zone". In the Netherlands, France, Belgium, Denmark one can read and understand at least some words because of the common Latin roots between them and German. In Poland you are lost :-D Most polish words seem to be a wild compilation of unpronounceable random letters - even for Germans.

@@Will-ui7dv lol

@@henryluebberstedt7819 And vice versa. Fun fact: Polish name for Germans is Niemcy - literally "men who do not speak a language". Do not blame us, it is over 1000 years old.

It is also a question of regulations... In BE, any aerobatic maneuver must by law end above 2000ft AGL, except in (beforehand duly authorize) air shows.

Really?! that makes so much more sense haha

Puchacz is designed to do that dive. It is in the POH

Judging from their entry speed and very low nose position as they go into the first slip (and my own experience side slipping the Puchacz) the "swap" was done because the ship refuses to stay in the slip and they swapped sides to mask them failing to put it in a good slip. Personally I agree, I wouldn't put that much yaw in that low. They probably had plenty of speed (hence the need to mask failing maintain to sideslip the first time) but Puchacz also had plenty of surface area to dump energy if she isn't flying with the pointy end forward.

sorry

That's not quite true, there are a lot of old glider pilots around :)

@@PureGlide Ya No, too bad their friends didn't make it...

Well a non pilot might say the same about gliding in general 🤔

Yeah I saw that ridge run, might do a separate video on it :)
