  • would this be an example of inertia coupling?

  • Low altidude for testing...

  • Yeah pretty sure its a hornet. Hud and warning noise sounds like it.

  • Comment removed

  • You just saw a guy almost kill himself.

  • at 1:04 he was 350 feet above the ground, during 2nd roll, when plane went out of control, aircraft stalled. Airspeed is in upper left box.

  • there are pilots and then test pilots one of that group is short  1 of 9 lives that was close but it does help keep the pilots out in the fleet safe

  • As much as I love the F-14, it is a DOG compared to the F-18 in any dogfight. The only advantage the F-14 has is the AIM-54; the target is toast before it has a chance.

  • @MrTaco0 The Phoenix could only hit bombers and fighters travelling in a straight line at a consistent speed. As for the F/A-18, google "War Nerd Hardware for Dummies." I'd be curious to see if this changes your opinion.

  • Do a barrer roll!

  • Another prime example of why the Navy should've keep the 14, Thing can go Mach 2.5, has a bigger unrefueled combat radius (since it doesnt guzzle fuel like a 18), and its the only aircraft able to carry the AIM-54 Phoenix which has a range of 150 NM (the longest yet developed). Oh and plus it could out manuver a 18 in a dogfight even tho its a bigger bird.

  • @GoldPicard - Your facts are (may) be correct except one. A Tomcat can not out manouvre a Hornet. The F-14 bleeds way too much energy in turns to be a good dog fighter. It was never designed to be. It's a fleet protection airframe with long range, great radar, and the AIM 54 Phoenix. It was also extremely expensive to maintain and keep in the air. Similar to the F-111, which us Aussies retired only recently. Don't get me wrong, I loved the Tomcat. But Hornets can now do the same job and more.

  • @smeary10 The F-14 actually turns better at lower speeds than both the F-15 and F-16. It was designed to be a turning fighter.

  • @okisoba

    No it wasn't, it was designed to be a long distance interceptor to degend the fleet, it used Phoenix missles, longest range A2A missle designed. It was not a bad turning fighter but that wasn't it's main role, far from it. I think your trolling...

  • @DrWatson08 Yes, it was. I am correcting a common misconception. The fleet air defence capability was one requirement. The F-14 was designed from the outset to perform the full spectrum of fighter missions without compromise. Look up George Spangelburg (sp?). His daughter created a website with many of the original documents and correspondence regarding the F-14 during its genesis. He was head of development at NAVAIR from the 50s-early 70s.

  • @DrWatson08 Spangelberg stated the F-14 was to be an air superiority fighter first and foremost. In addition, Grumman, as well as the Navy, stated such. The NATOPs for the F-14 states that as well. Lobbyists for other programs and a lot of British aviation writers like to perpetuate the F-14 was designed mainly for long distance interceptor only idea. That is absolutely incorrect.

  • This is an FA-18 doing a flight test event a PAX river for Blue Angel flight control computer differences. The Blues fly with modified FCS software and different artificial feel system, as well as performing maneuvers generally prohibited (like multiple rolls). What you see is "coupling", where movement in one axis translates into another axis (roll, yaw). This video demonstrates the reasons for having special Blue Angle software, and the reason for testing it.

  • god 350ft... i know it sounds really low but to be honest thats lower than low. still atleast u dont don do it when ya do ya pilots licsense !

  • spiked at 8.3 G's

  • 350 ft lol

  • ha you saw his IAS go down to less than 50... ouch. Bet he never made that mistake again.

  • the nose wallowing you speak of is not an issue with the aircraft. its an issue with the nozzle direction. the aircraft rolls repeatedly and fast enough to lose straight tracking because of the thrust direction. you dont have these issues in aircraft with directional thrust. and again. this is an f15 not an f18 super hornet with direction thrust like the blue angels

  • @hatehasalullaby This is 100% a F-18 HUD Not an F-15a/c or E

  • that was intense!

  • Great to watch! Thanks, not sure where this mach 1.5 comes from, pilot clearly says 400 knots early, and HUD shows mach 0.64 - watching that G meter - over 8 on recovery, nice, there's a couple of flying hours off that airframe's lifespan!

  • "ALTITUDE, ALTITUDE!"

  • what happend??

  • The pilot shit his pants for sure!!!!

  • YOU FUCKING DEAFENED ME YOU FAGGOT GODDAMIT ARGHGHH~

  • CF-18 pilots call it " falling leaf " wind changes and hits the tail putting you from a roll into a spin

  • Comment removed

  • theres nothing scaryer then tail spining like that..

  • Mason pilot is CORRECT! I can stick my leg out along side the front of an OH58 (bell jet ranger) and the static instruments would go bonkers inside the cockpit. If you expect only "slight movement" then Ooooh you're in for a big surprise!

  • RTB Return to Base

  • RTB GUYS! =D

  • alltitude alarm at 1:00. dwam

  • Just watching that made my asshole pucker up...

  • Wow...can't believe he's testing at 4000 feet. This ride is actually more insane than most people think. Watch the altimeter when he first loses control. At 0:48 he's not just spinning out of control, but he's rising and falling! He suddenly shoots up to 5000 feet briefly, then drops to 3900, up to 4000, down to 3600, up to 4300, down to 3400, then it's pretty much all down. I'm pretty sure I saw his G-meter on the lower left hit 9.7!!!

  • @rtrThanos The altimeter was incorrect during the departure from controlled flight. Static ports (where the altimeter gets its reading from) are made to work with "normal" flying airflow over it. You start spinning the aircraft and the static port is going to get weird readings due to the crazy airflow causing changes in pressure all over the aircraft (including over the static port(s)). The altimeter was simply showing the pressure changes around the static port.

  • @MasonPilot06 I think you are mistaking static ports with pitot tubes. The static ports are small openings on the airframe which are not susceptible to airflow and therefore will not give incorrect altitude reading.

  • @unapro3 Negative. I know the difference lol. Static ports measure the static pressure at the port. Static pressure CAN change depending on airflow around the port. Static port locations are design to give a accurate reading during NORMAL airflow/flight. However if you change the relative wind to unnatural angles, it can create pressure differentials on different parts of the aircraft. Just go blow into a static port (increase pressure) and watch the altimeter descend :)

  • @MasonPilot06 Static ports don't measure the pressure at the port, they allow the static air pressure to enter the static system which is a plastic tube connected to the altimeter. Inside the altimeter there is a small capsule that looks like a set of bellows. These are called aneroid capsules. They are a sealed unit. As the aircraft climbs the air density becomes less, this means the air pressure in the sealed bellows is greater than that in the altimeter, so it starts to expand.

  • @unapro3 now the needle in the altimeter is mechanically connected to the bellows and this is how it moves. Just blowing on a set of bellows will not cause them to expand or shrink. If you blow hard enough into one static port with the other sealed you may get a very slight movement if you manage to increase the static pressure in the altimeter but this would not happen due airflow.

  • @rtrThanos You did. 9.7 g.

    I don't know much about planes. What do the two boxes on either side of the control interface [located near the top of said interface] measure?

  • @HaloPokemon5Master the right box shows your height in feet, not sure about the left one, i think that one's speed in nautical miles.

  • @mynameisluigi1 And so I refer to the title of the video. HOLY. FUCKING. SHIT.

    This guy had an angel watching over him. Or he's just a badass pilot.

  • hmm... this will make me look stupid but whjat i would do is eather flip on the after burners and speed up or, thow myself into a dive to get some controll!

  • @whitewolf8401

    I would have ejected at 1500 feet. But that's right when he regained control, so no need. Honestly, I would never have been in this situation because I wouldn't have been doing testing at 4000 feet.

  • "i'm rtb guys. loss of control authority due to bowel release."

  • Rolling surface to rudder interconnect. F18 flight control software. This is a prohibited manoeuvre for Hornets. Hard way to learn the lesson...

  • hes quite stupid

  • Hmm... asymmetric loadout, maybe?

  • This was 18 out of Pax River. Test was low altitude high AoA aileron rolls in thick air.

  • So what happened there, did he loose control or did the plane fuck up?

  • Abberation in the FCC software. Aircraft lost lift and control surface authority on Port wing due to abnormally high AoA and extreme roll condition with moderate yaw rate, FCC software attempted to compensate, resulting in increased roll rate and loss of pitch and yaw authority. Pilot was able to regain control authority. Had this been an autonomously controlled vehicle, platform would have been lost.

  • now translate that in english pls

    u know not every one understands pilot language xD

  • Basically, I said it was a flaw in an early example of the Flight Control Computer's software build. The aircraft exceeded the Angle of Attack for a given airspeed/condition, during an aileron roll condition, and lost the ability to have the control surfaces on Port side wing respond to control inputs of the pilot, or rather, control inputs had no effect because the wing had effectively been stalled.

  • The nose was yawing about a bit, probably dude to low speed rudder correctional input by the pilot, and because of this, and the resulting departure from controlled flight, the FCC interpreted the condition as something other than what it was, and the computer controlled recovery procedure/control surface movements actually worsened the situation. If it was a UCAV with no human operator, the aircraft would have crashed as the FCC could not rectify the situation.

  • i'm not an airfcraft engineer, but it's not a stall...i think...

    a plane can stall at every speed, if the AOA's plane arrive to overpass the critical angle.

    Looking at the video i think that fighter's critical angle is not overpassed...so...someone knows what is happened?

  • Looks like an 18 and the departure is characteristic of an 18. When you roll the 18 continuously the nose doesn't track, rather it "wallows". This leads to side loading on the fuselage and eventual departure if you keep it up, especially at high speeds.

    One douchebag 18 driver thought it'd be cool to do multiple aileron rolls at 1.5 mach to show off and departed the jet so spectacularly it ripped half the wing off.

  • @sneakylilbastard - You could call it "inertial roll coupling..."

  • @sneakylilbastard

    this is incorrect. Not once did he approach mach 1.5.

  • @sneakylilbastard Just out of curiosity, how do the Blue Angels counter the nose "wallowing" when doing their performances?

  • @sneakylilbastard this old footage of f-15. there pilots, not drivers. and hes testing g load limits. thats why he repeatedly says setting my zero g. this is when hes relatively level with no positive or negative g's. then he sets zero g's before starting the test. the spike he refers to is the g limits spiking as he rolls. also he was at 2500 and dropped to 400 feet. hence "too low to get out" or eject. this suggests g load tests because g's have less effects at higher altitudes on theaircraft

  • @sneakylilbastard sounds like ur an aviator. what branch, may i ask? if you know the 18 that well i would say either marines or navy.

  • @sneakylilbastard By "track" and "wallow" you mean that the nose won't stay pointed in a direction as it rolls, and that it kind of moves all over the place?

  • @sneakylilbastard I didn't know that you drive planes.

  • @sneakylilbastard So why did it go out of control the second time he tried his roll under the same conditions, airspeed etc?

  • @sneakylilbastard yeah you could TOTALLY see that in the second roll - there was an eccentricity to the roll that didn't even look stable from the get-go... freaky.

  • War of Independence against the British...and youre calling me ignorant. Yes Greek partisan resistance played a minimal role in WWII and the demise of the German Reich. Lets hear it from a Greek...how many Germans were stationed in Greece during the occupation? How many Germans were killed by Greek Partisans? Cite your sources.

  • For some reason i can not put a link for you to read just a small piece of Greek history. I tried twice.

    Anyway. I will try again later. But for now i will let you with a quiz.

    Do you know who said the following ???

    "The unbelievably strong resistance of the Greeks , delayed by two or more vital months the German attack against Russia. If we did not have this long delay , the outcome of the war would have been different in the eastern front and in the war in general."

  • I will give you the answer in the next post in case you you want to look for it for yourself.

  • So... because i dont see a reply from you i inform you that the above phrase was said by

    Wilhelm Keitel , who was Hitler's Chief of Staff.

    And to sum i have two more for you...

  • Until now, we knew that Greeks were fighting like heroes; from now on we shall say that the heroes fight like Greeks.

    Said by.

    Winston Churchill, Prime Minister of Britain - 1940.

    If the Greeks had not resisted and had given in to the Italians, then the chain of events that led to the ultimate downfall of the Axis powers would have been radically different.

    From the Nuremburg Trials - 1945

    So go read a book and next time be more careful to whos country's history you insult.

  • Uhh...I'm RTB (gotta change my shorts)

  • Ballz of steel man!

  • @Skypirate03 LOL

  • Is that an F-18 HUD?

  • def a shit ur pants moment...i jus dnt understand what he was trying to do tho..i mean was this a test flight or sumthin? did wel to recover so quickly tho

  • Now thats a DEPARTURE!

  • 8,3 G

  • what the.. what was the plane type? CG point must be really back of the plane or the wing dynamics fail below 400kts TAS. First rolls with 400-420 kts was just and just, but 380 it had helluva drag. Jesus.

  • By the layout of the HUD i think it was F/A-18 Hornet C/D model maybe. Remember that CG point changes whith speed but that doesn't matter much in FBW plane.

  • Yep...Americans have the greatest Air Force in the world...and the Greek military is a damn joke.

  • who also use US aircraft

  • great...the equipment doesnt make the pilot or the overall quality of the military.

  • Who says hshit etc? instructor on the ground or in second pilot seat?

    What is really funny is the sound. I was almost expecting to see '7 LIVES LEFT, INSERT COIN TO PLAY' on the HUD. At the same time the plane got 8G! this is why I wonder if the 'hshit' instructor was IN the cabin - he shown no problems with talking during high G.

  • Man he dropped from over 5000ft to about 360, thats a propper tumlbe. I bet it was brown trousers time.

  • He only reached about 3800ft ;)

  • Comment removed

  • Roll coupled departure is what happened...

  • f18:D

  • that did'nt go so hot

  • You can stall at any speed all you need is to disturb the airflow over the wings enough. He was at almost 400 knots when he stalled. In a 16 or an 18 you have to fight your instincts to grab control. The instructors tell you to take your hands off the controls, the plane will right itself. Looks like it worked.

  • He departed controlled flight but I don't believe a stall was the problem.

  • You can't stall at any speed :)

    But as in this exampel the plane is rapidly slowing down by the assault on the stick and rudders that the pilot is making.

    And evantially he got himself in a stall and spinning out of controle, if he hadn't recovered the plane that fast, he would have been killed.

    And letting go of the stick in a deep stall is suicide, the plane won't recovered then.

    My guess is that this is a video of testpilots doing a routine test. But it almost had a fatal ending.

    Grtz

  • Yes, you can stall at any speed, when the angle of attack exceeds the critical angle, 15 deg for most light aircaft but much higher for fighter aircraft, the airfoil will no longer produce enough lift to overcome the weight. The aircraft in this video departed at about 400kts, so this kind of proves that you don't have to be going slow to stall.

  • Everything you say is true, but the AOA is deepending on the airspeed, so at 400knots you can go to 90° straight up and come level again without going into a stall. If you would try that with 200knots, a can garanty you would get into a stall.

    But in this video he has a beginning speed of 400knots, you see it dropping to 380 or so, and when he starts getting in the stall, his speed immediatly plummeds to even 40knots, he is falling out of the skye. But he was assaulting flightcontrols!

  • What you are describing, 400knt vertical, is called zooming, but the AOA is still zero relative to the airflow when going straight up. When he is doing 40kts he is probably not actually doing 40kts it's just that his pitot tube is now in a position relative to the airflow that it is not getting the flow directly down the tube. Once you understand AOA RELATIVE TO the AIRFLOW you will be able to understand what I am trying to explain. AOA is different to the Angle the airfoil is to the ground

  • I know what AOA is, its the difference between the guncross and the piper to make it easy :)

    But I know what you mean, it is possibel to get in a stall at all speeds, as long as you try hard enough :D

    But that, is off course, not something you want to do ;)

    But most common exampel of stall is that you just go to slow and fall out of the sky :)

    Thx for explanation, take care ;)

    Grtz

  • @unapro3

    The AOA is the angle between the nose of the aircraft and the actual vector it is traveling. Simple.

  • @kingneptune117 You're close. The AoA is the angle between the vector (relative airflow) and the chord line of the airfoil. It has nothing to do with the nose of the aircraft.

  • Angle of Attack is the wings direction of trave in relation to the air, but it has nothing to do with speed, its the direction the fucking with is pointing, not the direction the aircraft is traveling. If the aircraft is pointing nose up, yet the aircraft is traveling forwards, its angle of attack is high and above a certain degree it will stall, its not saying you can't fly upwards, its saying you cant travel forward whislt pointing upward.

  • You really don't really know what your talking about do you?

  • I really don't know really what you really ar talking abour, really?

  • I think blackbirdbe is arguing, when he really don't understand principles of flight.

  • is he not seeing if a student can handle it or something? if so i think he passed the test lol

  • lol, this wasn't a student, my guess is that this is a testpilot, they push it really to the limit to get important information about the plane, so they can set up standard procedures for all pilots using that plane if they get into a stall.

    And this really was a deep stall!

    If he hadn't recoverd the plane that fast, he wouldn't be here anymore.

    Great flying skills kept him alive!

  • Jesus christ

  • He didn't do it.

  • true, but the pilot was very close seeing him in person... ;)

  • Wow, stalls arnt good. Never imagined that a fighters could drop like that, its like a stone :)

    Scary.

  • LMAO thank god hes ok tho but still LMAO :p

  • If you make a habit of practising spin recovery manoeuvres at 2000ft you are going to need a lot of clean underwear.

  • what is he flying

  • looks like an f-18 judging by the hud

  • I was to low to get out, oh boy.

    hhaha

  • I said shit 50 times during a car accident while I was spinning down the embankment.

  • I am no pro, but I kinda could see it coming from the start.

  • RTB to clean his shorts!

  • jesus christ! you don't want that happening with only 2000FT to recover..

  • Scary,but VERY INTERESTING!!

  • stall?

  • What happened? Why did he lose control?

  • WTF is he doing spin recovery manoeuvres at 2000ft.

  • It was not intentional spin recovery, it looks to be aileron rolls and it looks like 3000 ft not 2000

  • Thats an F/A-18 right?

  • rgr that is the f-18

  • heh heh - nice one

  • HEHEHE, I'm RTB guys!
