This video is awesome 👏🏻 Test pilots risk everything to gain just a minuscule amount information and in doing so they are potentially saving the lives of future pilots. Absolutely a phenomenal amount of courage these guys & girls have.
Amazing. Incredible courage, skill, and intelligence, Test pilots have to be some of the most special people there are, don't you think? Makes you realise how much dedication and bravery goes into the development of fly-by-wire systems in inherently unstable planes. I've heard it described as sitting on the front of a car at 60kph, pushing a bicycle in front of you backwards, holding the handles and trying to keep the bike going straight...
The discussion by "Deuce" Brophy was excellent! He was to the point, succinct, and lucid. I appreciate these explanations, since it only increases my bit of knowledge. Thank you for this good video.
Gil Mosko I agree. I am not a pilot; always wanted to be, but my eyes were not AF "OK". So I read, and watched, and learned. I understand G forces, and IIRC, the F-16 has a 9 G limit? So by being lighter in weight than was estimated, the force applied by overcontrol had a greater-than-expected result on recovering control. Am I correct? So the affect was, there was nothing wrong with the S/W upgrade; it was a lighter-than-estimated aircraft weight which caused the unexpected result of the test maneuver.
JosephK109 The presenter said that the g-limit was encountered due to post-departure gyrations due to the inherent nature of the aircraft. Seems to me this test was about whether or not the flight control system has the authority to recover after a departure in this situation. It did. Seems to me everything went as planned except for those gyration forces. But I would comment that if a computerized flight control system cannot account for changes in weight and causes departure because of it, seems to me something’s wrong with the flight control system. 😉
CAVU skies to all aviators. Nearly died in a spiral dive in thick cloud myself. Wanted to quit, to panic, but my training saved me, "Power back to idle; roll wings level using artificial horizon; pull HARD; when the little bird well above the black, full power." Death just seconds away. It changes you. I'll never be so scared again!
You have found a subscriber and I, finally, have found a military aviation and general aviation video channel worth watching (and listening to. Thank G-d, a human voice!). Now, to explore...sharp aft stick, "bootful" of right rudder, and departure from controlled flight...
I am going to go fly an F16 backwards. You can't do that. Hold my beer and watch this. That was incredible, and it looked like he was in departure for a long time. I wonder what was going through the test pilot's head after several seconds of THAT. Those guys have balls of steel, and a lot of skill. This is an awesome piece of flight footage. Whoa Nellie!
Hi, RJ Thanks for the critical eye. Two things: 1) The RUclips version isn't out of phase when I watch it on my system and the original file is fine, too. That said, I'd like all my vids to play properly on the computers I'm not using that access the internet through service providers to which I don't subscribe. I'll see what I can do. 2) You get what you pay for. So, expect your refund check in the mail and I'll expect mine from RUclips. ;-] Best, Glenn Pew
@@TurkishRepublicanX Yeah, new Block 70s but the C & D initial flyaway unit cost was $20M. USAF isn't buying new F-16s (yet). The new batch production is for foreign export. Those are $60M+ depending on systems.
I was trained on flight characteristics of the F-16 because it was part of the class of aircraft I was trained to work on in avionics. I do remember when that type of loss of control on an F-16 was fatal to the aircraft.
I had a FCC (flight control computer) anomaly during a BFM flight in the mid 90s in a Block 15 F-16A. During a hard pull the plane yawed. The snap roll at 400kts was violent and huge induced yaw . While in the “tumble I looked back to see what the controls were doing and I watched the stab move the whole travel +/- 60 degrees and the rudder flap a bit. After about 3 oscillations, I was at 200 kts going about 20 degrees nose low. It was “fun”. After we landed we downloaded the video and all 5 recording parameters and sent them to General Dynamics. Faults were in the FCC and there was an over G. 11plus positive and 6 in asymmetric. The plane was ok, little damage but was taken apart extensively. It appears one stab went nuts during the pull and failed. The plane recovered on its own. The data was compared to flight test data and similar points were obtained earlier . It did what it was programmed to do and recovered itself using the remaining flight controls . So the point was, “we have those data points” someone went out during testing and flew similar profiles during flight test! Geeezzee. They are true heros and gold star pilots like Deuce! Flying to the unknown and back daily……. Great video!
I used to get into this situation on Falcon 4.0 sim when carrying a full bomb load while maneuvering, even with the bolck 50 upgrade. Even turning off the pitch override, trying to wiggle out of a deep stall didn't always work and I ended up bombing the enemy with my whole aircraft.
I had a voodoo gfx and F 4.0 was awesome. I loved to call in an emergency and get guided back to the airfield. I could also deadstick land the bird. To minimize drag i jettisoned external fuel tank and missiles.
John O YOU didnt get into ANY situation your crappy ass stupid video game did its in no way at ALL even remotely kinda sorta mabbee the same .... now please sit down yer mommy be here pick you up shortly take ya for ice cream
You're just proving my point about test pilots. Every last ones out of their ever-loving Minds. Will you guys do is insane. Do me a favor and don't break any of my aircraft
I went to elementary school with this guy. We called him spaz because he was massively hyperactive. I made the mistake of picking a fight with him one day. His hands were so fast I couldn't get near him so I just gave up, apologized and never bothered him again.
I deleted my old comment because I listened to this video a few more times attempting to learn what happened here. The excess G limits were in the "rolling" direction during the departure phase of the maneuver. Since the airplane was lighter than expected, the G "limit" was higher than they originally believed. Therefore, they did not overstress the jet in the "rolling" moment of the departure phase of flight. I think.
Rolling-G limit is always lower than symmetrical G-limit. Because to roll, one wing must develop more lift than the other. If one wing develops more lift than the other in order to roll, and you pull to maximum symmetrical G limit, while rolling, then by default one wing is below that limit and the other has exceeded it. Typically you will see a ~25% reduction in allowable limit G load with ailerons deflected. This is one of the reasons the Extra-330 has a wing rated over 22g ultimate, for an aircraft that has a published limit load of +/-10g. Because aerobatic pilots don't always reduce G while rolling. This is of course at a defined gross weight. If the aircraft is lighter, the wing will experience less stress at the same G-load. Therefore, you have more margin between structural failure at lower weights. Allowing you to exceed the published G-limit before actually exceeding the structural bending limit of the wing. But, this assumes the reduced weight was removed from the fuselage, and not the wingtip, or anywhere outboard on the wing. A reduced fuselage weight means reduced wing bending moment at any given G-loading. An F-16 carries a substantial part of its gross weight as internal fuel located inboard of the wing, mostly contained in the root. It consumes this fuel at a staggering rate, often exhausting its fuel in a 1.5hr mission. Or as little as 15min with afterburner. So, if this test required climbing to altitude, cruising to a test area, and performing maneuvers then it probably consumed a substantial portion of its fuel by then. Maybe 10% of its mission takeoff weight. Therefore, this maneuver might have exceeded to published rolling G limit assuming gross weight. But at the time of the incident, the aircraft was light enough not to over strain the structure. This applies to Cessnas as well as space shuttles.
Wow, I made my comment five years ago? It seems more like five months ago. I think I get your point. Looking at it another way, if the g meter is on the longitudinal axis or centerline of the instrument panel and it reads the max g during a rolling moment, the g meter will not be reading the exact amount of g being exerted on each wingtip. Your point is that if the g limit is read at it's max allowable as per the g meter, at least some other point on the aircraft will be exceeding the maximum load limit. I think that is what you are saying. Anyway, thanks for the reply. @@TheJustinJ
I saw an F-16 at Edwards come in at low altitude, depart controlled flight and then accelerate out in a different direction. Whole thing took about 5 seconds. When they landed the computer tech in the back seat looked kind green...
I don't understand why did it go into a right spin when the asymmetric load and drag was on the left side. One would think that the aircraft has a tendency to spin to the left in that condition.
What I didn't hear was the method of recovering from the departure. Perhaps the pilot used the Towel Rack Recovery" method. Never the less I'd like to hear more. Great vid, I'll be watching.
Air density, and therefore q, are much reduced at 35,000'. Somewhere in the range of 0.3. An aircraft surface can only generate a certain maximum lift coefficient. Usually in the range of 1.28 (flat plate) to 2.0 (high lift airfoil). The structure only needs to withstand the force it is capable of generating through aerodynamics under a given free-stream condition. An aircraft capable of sustained 9g flight, where it requires ~ 400ktas at sea level to attain, is going to be virtually impossible to break at 35,000' while subsonic.
Were pants evaluated for Yaw and tumble slippage? He basically lost lift as the angle of attack was rapidly demanded from the pilot. Same thing happens in a Cessna if you turn too sharp into your final approach.
That would seem to qualify as a flick roll. (Hard back and full rudder's the usual input to induce one, if I recall correctly.) Not usually performed by machines festooned with stores.
I can't really work it out from what he said but he did mention something about " to induce departure rapid aft stick was input" not only did this cause departure but it caused some side slipping (β) as well, perhaps the departure and side slip effected the direction of spin. Once spin is established it is anyone's guess what happens.
Yes, I agree that the sideslip determined the direction of the spin.I was puzzled by what he said that with the missiles on the left you get the effect of putting in full right rudder.Maybe the flight computer feeds in right rudder in that configuration and that's why it departs that way.
Beautiful...... my dream is to fly one of those babies. Watching these test stunts just gets me "aroused" even more. ;) I had a pilot explain to me (in detail) how to do those stunts one time; but I was just undereducated enough to not retain any of it, as I hardly understood it at all. Hopefully I'll be testing aircraft like that someday....
This does not really make sense to me, wouldn't one expect that the rolling G limits would be exceeded given the means of approach that is being used to get the aircraft to depart and what you expect the aircraft to do in it's departing of controlled flight, one expectation would be the exceeding of those G limits wouldn't it be? Also wouldn't you know what the base weight was initially, why would that be something that was needed to be computed.?
The weight would be recalculated after the flight to compensate for fuel burned to the moment the departure from controlled flight occurred. In this case it makes the difference between ground a plane for over stress inspection and delay of the program.
Inertial Coupling. I read i a description of Milburn Apt's flight that got into that, in Neil van Sickle's Modern Airmanship book. And there is an essay "Chuck Yeager's Wild Ride", on the Internet. (I don't remember whether or not he 'inertial coupled'. But Milburn Apt crashed.)
So this was a test of software, but the pilot recovered the plane? Or did the pilot test a auto levelling feature like in the mig-21 where you press a button that recovers the plane to level flight?
Would that be 1812, "54 40 or Fight!" or The Alaska Boundary Dispute? Our cousins have had a few run-ins, haven't they? The history of Canadian American Relations is a truly fascinating subject for study.

+213ASDT Exchange pilots. Happens pretty regularly, so our various allies train with us, and our pilots train with them. If you watch Jetstream, you'll see two Australian officers training RCAF Hornet pilots. There have been American Hornet drivers at that school as well.
We had a German pilot in our U.S. Navy fighter squadron in the 80's.
We get RAF, RAAF, RCAF, RNZAF, JAF, pilots flying exchange and our pilots do likewise.
Good 'Ole Sierra Hotel boys club. They yearn for the days of the original Muroc and Jackie Cochran's "watering hole ranch" with all the bennies.
@drbackjack Also by his rank and wings, and of course his friendliness
Broca's area well developed I'd say.
excellent vid. thanks for posting!
So it essentially stalled and started to spin. I wonder what air speed it reduced to during the spin, and at what speed it fully recovered.
I think the "BALL compartment" extends far behind the trailing edge of the canopy in this particular aircraft.
Yeah, that's was a pretty serious stall there
I cannot imagine being told "so i need u to basically make it uncontrollable and recover it so we can see what the limit is"
Mayday Mayday Maverick’s in a flat spin , heading out to sea !
