F-22 Departure Recovery
Вставка
- Опубліковано 30 вер 2024
- In aviation, any time the aircraft does something uncommanded (ie gets out of control) it's called a departure from flight, or just departure. This shows a spin recovery test, and demonstrates how well the F-22 can recover from something like that.
Pilot: Holy S**t...
Observer: Copy that.
*imminent flat spin*
Pilot: "Yow. Whoa."
Balls of fucking steel
Thrust vectoring nothing to be afraid of a flat spin

@@wolfan8057 F-14 didnt have tvc
@@ambush5682 ik i was talking about the f-14 not being able to get out of a flat spin easily
@@chugwhiskey6605 This was not a spin, it was a deep stall departure condition more akin to an F-16 departure than an actual spin.
This is an old video from a developmental test of the F-22 and I thought I would set the record straight on this since there are so many false comments about this event. I am actually the test pilot in this video circa around 2001. This was not a YF-22, it was one of the EMD jets, tail number 4002 at Edwards AFB over the dry lake bed. It was not expected to occur and at the time we were testing for departure resistance and ran across a condition that the FCS did not handle well. It was a very wild ride but I recovered it and flew it normally back to landing. As far as I am aware this is the only departure of the aircraft during development or operational use. Minor corrections were done to the FCS and it was resolved and we retested the condition and all was well. The F-22 is an amazing aircraft, we should have built 1000 of them. I am not sure how David Williams received this video but it is authentic.
Thank you for sharing
its really awesome you're here - but how much can you share lmao
@@SlothOnMeth Not much more, I shared what I can. Not a lot more to it really. What would you like to know?
@@RaptrDriver Did returning the aircraft to controlled flight involve a conventional spin recovery method or was the "controls release" over the radio indicative that the aircraft came back on its own? Either way, getting out of and returning to controlled flight in 3,000ft while 36,000ft up is a bold achievement for the raptor program.
That was our test director in the control room and they could see the real time data and knew something bad had just occurred. He was just acknowledging that they were aware of the event that I was commenting on. @@thedarkmagician4141
"Holy S*DEEDLE DEEDLE*t."
Copy that…
how am i just now discovering the wealth of hud footage on youtube im having the time of my life learning from all these pilots
Usually departure tests are designed to discover the limitations of the aircrafts "normal" flight envelope, whether it be in the Beta, etc... This is a very good demonstration of the thrust vectoring nozzle's use in regaining control authority when the control surfaces are ineffective.
Wait was this an accident or recovery test with thrust vector?
Not quite. The Yf-22 control surface allows the aircraft to point and manuever the way the pilot wanted it to do. There was a quote from a book that the pilot stated the aircraft does what I want without the use of thrust vectoring. He said that thrust vectoring was extravagant. He basically implied that the YF-22 can outmanuever any aircraft without the use of thrust vectoring.
My mistake. This is an F-22, but the pilot who tested the YF-22 said so.
Thrust vectored ng wasn't used to recover from this departure. The test pilot released the controls
@@soccerguy2433 true, thrust vectoring was not used. The pilot can do this too, but the computer just do it for him.
Beautiful sounds. I wish we knew more about the F-22's systems in that regard.
Try this video. It blew my mind how complicated the aerodynamic surfaces are on the F22. ua-cam.com/video/22u4qxm1YjY/v-deo.html
"if I told you, i'd have to kill you"
“Plane starts behaving in weird way”
Normal people: “oh fuck”
Test pilot: “yahoo”
I love the progression of “Yahoo” “Yow” “Ooooooh” as he went from thinking “nice” in his head to “oh fuck”
How hard is it to actually get a f22 to depart from normal flight? I figured the amount of systems to prevent this would make it nearly impossible to throw it around like that. Are test pilots given more authority over its controls or is there somehow to override it like a button in the cockpit?
Title says YF-22, which was the prototype, not the production aircraft. Probably did not have a full suite of safeties.
I think the FCS was overridden
They must have disabled some functions when doing tests.
See my reply above. The F-22 is not supposed to ever depart. This was a developmental flight of the F-22 (not YF-22) and we ran across a condition that the FCS did not handle well. It was corrected and as far as I know has not happened since. This was an unexpected event.
This isn’t the YF-22, it’s an EMD F-22, I believe 91-4002 or 4003.
Ship 2
Correct, ship 2, 4002. I was the test pilot during this event.
@@RaptrDriver I recall from a talk by either JB or Steve Rainey about this particular test, where it was essentially an edge condition of massive loads imbalance combined with full aft stick, roll, and yaw inputs. I recall one of consequences of this was the max yaw rate being halved.
@@HaochuanNi This was common during these tests. It wasn't necessarily a massive imbalance, but we would run the fuel from one side to the other to create a lateral fuel imbalance. The jet "knows" it has an imbalance and changes its limits to include the yaw rate limit. In this case the FCS was not able to hold the jet within the yaw rate limit and it led to the departure. I can't get into the issue that was corrected but a change in the FCS control law corrected the issue. The jet was designed to never depart regardless of condition.
That pilot is Midwestern "yaow, woah!"
This is the first time I ever heard a f22 beep.
*MIB appear randomly*
"....so how did you get this footage?"
nice stable exterior shots from the guys on the photo tracking mounts...
The external video of this event was actually taken from ground cameras.
Departures are more fun than you should be allowed to have. For a while you're just along for the ride - then you get to see whether - this time - you can recover...
You gotta see the vectored thrust out of control video for this airplane.
No vectroed thrust was done on this video. All was done with control surfaces, but it can do more than what we see in this video; however the pilot can't handle what the Raptor can do.
Everyone talking about the f22 and I am like is that area 51
Same....
Because you mentioned it I got curious...
It doesn't match the groom lake test site at all. But if you see the airbase at 0:25 its the Edwards AFB Auxiliary base, you can even see a highway which is highway 58 in California. Here's a Google maps pin. 34.984985,-117.851871
Hey CIA if you see this please hire me lmfao.
Nope! Edwards! They only use Area 51 for updates to the Cessna 150, as they babies are top secret stuff 😏
its quite impressive how quickly he regains control
he doesn't do anything, at 0:17 you can hear him say controls release, which means hes letting go of the controls and letting the plane recover on its own
@@_cyantistyes I watched the video, thanks for adding literally nothing 😂
@@djmicrowave6073 my comment was basically saying he doesn't regain control the plane does it for him, so its not impressive how quickly he regains control its impressive how quickly the plane regains control
It sounds so quiet in the Raptor
that was area 51 can tell by runway length that high wow
Looked like Edwards AFB test facility to me.
@@-Spatz- Good eye - That is absolutely EAFB.
Basicly its how my plane fly in simple plane
Very dynamic stall characteristic....
My F-22 does that on X plane and infinite flight.
Dream on.
Get a life and get out of your parents basement gaming isn’t real.
looks like area 51?
Added to favorites!
See the stuff fly onto the HUD at the end there? That's literal shit.
When you do aerobatics you have this shit all the time floating around you when you are in negative G. This year i got something of this stuff into my eye and immidiatly the aerobatics where over...
So vacuum your plane before going negative.
@@MisterIvyMike Should be even funnier with the gyro maneuvers...
This is not a YF-22.
It's a raptor, right?
@@emiliorosales9196 Yes. The YF-22 was experimental, the one in the video is the production variant.
@d c
No, you're wrong.
This has nothing to do with the YF-22.
The video shows one of the first built F-22 Raptors in flight testing during the EMD (Engineering and Manufacturing Development) phase of the program.
This flight was in the late 90's or early 2000's.
195 F-22A Raptors were built:
9 Test Aircraft + 186 Production Aircraft
I know that the first 3 Raptors ever built had the pitot tube/instruments in the nose at least at some point during those years:

Falling with style

Wonder how the motors didn’t flame out?
Many valves and a good FADEC ^^
Flame out from what? Negative G's? The F22 has small fuel tanks internally so when you pull negative g's thoes kick in
@@discordmemes6924 For real? Damn, that's cool.
@@hunormagyar1843 Yep, all fighter jets have that, they would flame out if he kept pulling negative for 20 seconds though
Or as a competition aerobatics pilot would say "trying to fold the map on a typical cross country'... :p
„holy shi-“
„Copy that“
"Yahoo" 😂👍
At 00:21 you can see some dirt coming up from down and floating around the HUD. It looks like the pilot experienced some nice negative G at this time... 😂
First time I did one in training IT SNOWED in the cockpit. The climate control system had a 'feature'.
Using some kind of UFO tech. Clearly. Thrust Vectoring doesn't allow this type of shit. It allows corbras, falling leafs (which this is kind of that, but not really), super sharp J turns and skipping (aka tails slides). But not this.
What this thing is doing is not normal. Not even for SU-35s, which until this thing is in the air, is the most menuefurable jet in the world. And the SU-35 came out 13 years later and isn't stealth.
There's clearly some off planet tech going on here. Lets not kid ourselves.
Did the pilot make inputs, of did the aircraft systems get control back?
He states he's released controls, I would speculate he forced the aircraft into the spin to test the avionics ability to right itself :)
not quite@@olidoran2485
Holy shit
"Copy that"
Not a YF though
just a stall ... and what ???
F22?
Spin test?
Maybe not spin but definitely flirting with departure. You can see the spin chute mounted between the verticals so it was doing stuff where a departure was either planned or anticipated.
is that area 50!!??
Hero
Is it true that regain control you let go of the stick ? In my job we say things never go a little bad. That is super true to combat pilots.
Machinen Kanone for a spin you recover by maintaining neutral ailerons, applying opposite rudder and pushing nose down
To recover from a stall, yes. To recover from a spin, no
@@psyience3213 depends on the airplane
on the F-18, F-22 and F-35, yes. The flight control software will automatically take care of the recovery.
I think the point isn't so much a case of you let go to recover, rather you let go so you don't start wrestling with the aircraft and make things worse before you've taken a split second to breath, analyze what the aircraft is doing (is it spinning left or right? What type of spin? Will it recover if I leave it alone or is it stable in this out of control state?) and then make deliberate control movements to recover the aircraft. If you wrestle with it purely on instinct there's a good chance you'll just make things worse.
AOA limiter
He forget to unpress it.
Edward. At down?
Was it minimal stall speed test? What was the speed?
Hang on...was this another example of a fly by wire system deciding to pull rudder when the a/c is rolling with ailerons? I bloody hope not!
Spin test? Purposeful stall with aileron input....?
@@psyience3213 My best guess would be along the lines of that, putting it into a sudo tail-slide and using some control inputs to get it to spin out.
Meh, Russians do that on purpose for ten minutes at a time in air shows.
then hit the ground killing dozens.
That's how disasters happen.
Shade bwahahahaha right last I checked us military pilots were not selling joy rides to pay for their fuel like Russian pilots do.
Yep, at 1,000 AGL and still recover in time.
Bread& Butter - this guy is not a learning, this guy is a highly qualified and experienced test pilot flying very specific test points so that the engineers can gather good data. Note the flight test, air data boom on the nose. en.wikipedia.org/wiki/Air_data_boom This is not something you will see fitted to an aircraft with a learner at the controls.
F-16 can also recover from a dangerous departure because both of these aircrafts have fly by wire system and its easy to recover from anything for F-16
A bit like flat spin recovery, where you pull full up to unstall the elevators, so you can lower the angle of attack to unstall the wing?
F-16 is one of the first generations of fly by wire and without thrust vectoring, recovery from departure of flight is still very much a pilot skill thing as well, as someone mentioned sometimes one must override the fly wire system to defeat the issue, perhaps not on the newer models but one cannot really know of all the improvements that maybe done on a revision some maybe handicapped by the actual frame and classified data.
its nothing weird ALL metal planes recover that well
Simply not true many have died from something you just said doesn't happen
Su - 35 can do this easy
