757 goes vertical after flyby:

Only 45o. :aok

Pity we didn't see the complete manoeuvre. Looks like fun

Last time I "went vertical" I was on a kiddies' swing next to my little daughter.
I stopped it after about 5 secs.
I don't ever want to go vertical again.

Wrong as your name implies! This guy goes 90 degrees straight up! I will admit the film there stopped at 70 degrees so lets see the same thing on a different day!

It all depends on the equipment used :)

"A RNZAF pilot of No 40 Squadron doing his airshow routine at the RNZAF Open Day in March 2007. The plane is in fact pitched up to 45 degrees nose up by the apex of the climb."
You're being fooled by the angle of the camera and perspective.

Are you serious? Try posting an actual video of any Airbus doing a barrel roll in real life and not in a simulator.

Listen to it, its a buzzing noise.

Sounds fine to me, I've always known the 757's to have that sound effect. Being inside the 757 seems like being in a space shuttle almost on takeoff, even some pilots say "This is **insert callsign here**, ready for 'blastoff' ".

I'm no expert but it looks better than 45 degrees to me! nice wing over
-
the 777 could takeoff and climb vertically and accelerate for a while if lightly loaded...
the 757 is overpowered... I LOVE IT!
the 777 if lightly load is EXTREMELY over powered AND I LOVE IT EVEN MORE! 230k lbs of thrust for a 326k lbs plane its GREAT! :x
the 57 and 77 are actually my favorite commerical planes ever, then third is the 737NG.
on all of these flybys these planes are loaded only for the demonstration, so they arent carrying that much fuel which is why they can do this. the NZAF does have a habit of showing off their 57's lol

Turbofan engines sound like that.

An airbus can't do a 1G barrel roll. It can't do a roll of any type. The limiters stop the roll somewhere before 60 deg angle of bank. It's around 45 deg if I recall correctly.
-
Well ..
..I did a roll in a USAF B-52 sim at Castle AFB just to see if I could.
It was all about not exceeding the parameters of the equipment .. max level speed, pull nose up, start the roll as she goes up, and it took about 10k alt to complete it even so.
Not pretty and definitely not airshow material :)
The sim operator bet me I couldn't do it without exceeding something :)
I won the bet.

No they don't. Those on a non Rolls Royce 757 (Pratt 2000), 767 (JT9D) and non GE powered Airbus 320s (CFM series) will sound like that. The sound is the fan blades themselves hitting one another. There are blade bumpers installed on the engine to keep them spaced evenly and limit how much flex there is in the blades.
Rolls Royce Trent, GE-90 and CF-34s don't sound like that and they are without a doubt turbofan engines. Their fan blade design has the blades spaced farther apart and never touch thus not requiring such a system.

If you had watched the second clip I posted you'd know that by pushing two buttons (shutting down two computers) the pilot can get direct law control over the ailerons and alternate law over the elevators, thus being able to barrel roll the aircraft. Of course, any pilot doing that in a real Airbus would not be a pilot for long. The bank angle limit of the A320 with normal law is 67 degrees; you'd know that too if you had watched the first clip I posted.

Prove that it can. Even the Airbus instructor pilot casts doubt it can do a barrel roll in real life. Nice try reaching at straws but you've failed.

All aircraft are structurally capable of doing a 1G barrel roll; if done right it stresses the aircraft no more than level flight. the B707 pilot said so himself in the original video. No Boeing or Airbus will ever do that again and the 707 pilot got a WTF are you doing from his boss. Didn't any of you see the original video? Don't any of you know what a 1G barrel roll is? The stewardesses can continue to poor the champagne during a 1G barrel roll. Do you think Airbus makes their simulators behave differently from the real aircraft? That would be stupid, and thinking they would do so is silly.

People like you crack me up, you're wrong. You have failed to show that an Airbus can do a barrel roll in real life and you're just pathetically trying to spin your way out of it anyway you can. Too bad you're miserably failing at that too.
You may go now and sit in the back of the class and be sure to wear that Dunce cap.

Are you really this obtuse in real life or do you just play one? Neither of those are commercial jumbo jet aircraft and don't prove your argument at all and further points to your utter failure to do so. Keep reaching for that rainbow, it's providing us a lot of amusement.

A couple facts:
How many airplanes did Tex Johnston supervise as head of flight test for Boeing after his little "I'm selling airplanes" bit? You can count the number on no fingers and although he was ace of the base (if you were to ask him he'd tell you so) he was not there for the 727, 737 and 747 for a reason.
Hoover was not deadstick during his iced tea roll.
<edit>
My assumption was another link of the 707 prototype being rolled.
The 1900 crew should be dragged out behind a hangar and beaten with a shovel. Not only for doing it but for taping it. Not only for taping it but sharing it. Not only for sharing it but for having it placed on Youtube. Then again for doing it in the first place.
-

Oh? I missed that. Great pilot skills anyway.

I suppose you would. The way the airplane was behaving and its attitude notwithstanding the phrase "Secretary of the Air Force and a plane full of Generals" should allow one to garnish enough information that the engines available were in fact making noise.
While I can't say for certain and personally I doubt that video was made with said passengers on board regardless the airplane in the video is certainly operating with power.

Well, technically the B707 isn't a "jumbo jet" either. How little you know.
Keep the insults coming; they bounce right off. :aok

There isn't more noise in the "ice tea" cockpit footage than in the earlier cockpit shots. In any case the B707 isn't anything special, a 1G barrel roll is within the structural capabilities of all commercial aircraft.

Switching off the computers (and there are seven of them) would not result in direct law, but mechanical reversion. Direct law results if you did switch off some of the computers, and also if certain combinations of them fail, or certain components in the plane. Lesser failures result in Alternate law. There are switches on the overhead panel for all seven computers.
If ALL the computers failed (or were switched off), you still have cable control of the rudders as mentioned above for lateral control, and also cable control of the stabilizer trim through the trim wheel for vertical control.
I am an A320/319 pilot for America West, and they make us go through that scenario during training. It's a pain in the prettythang to control, but it can be done.
Maybe you should reserve that particular smiley for yourself...

Referencing your attitude. You don't have the first piece of first hand experience. For what it's worth I never said whether an Airbus could or couldn't do a roll. I have my own opinion and it will stay such.
-
Fair enough... Your own attitude could do with a bit of adjusting too. Falling off your high horse at that altitude can be lethal.
Furthermore you have no idea what I have first hand experience in doing.

That Boeing VS Airbus argument is stupid, both manufacturers make planes that have very close specifications and flight limiters set aside, I don't see any reason why an Airbus can't do what a Boeing does, and vice versa. But if you guys want to do a flag waving contest go on with it...
-
Indeed. If either company goes bust we, the consumers, lose. Unless you're protecting some investment (financial or otherwise) in one of the companies any favoritism is harmful and downright stupid.

You can roll an Airbus, just push the disconnect buttons to go into Direct law, as Die Hard said. You remove all the limitations of the computers, and the controls are directly linked to the joystick.
Would I want to.. no way, but it is possible.

Simply the wing design. The B707 has more of a "straight" wing design, while the A320s wing curves up to reduce fuel usage, which, inverveted, would cause a traumatic loss of lift.
-
:lol Wing dihedral angle affects fuel usage? Where did you learn that?

I think he got that mixed up with engine placement.

Well, you don't want much lift when inverted during a 1g barrel roll.

To form an educated opinion on this matter first you need to understand what a barrel roll is. At no point during a barrel roll does the wing produce negative lift; the angle of attack is always positive and produces positive G's. In a perfectly executed 1G barrel roll the aircraft will not lose altitude, it will in fact briefly gain altitude as the roll is initiated by pulling up into a shallow climb. When the aircraft is inverted the pilot is literally pulling the nose down into a 1G inverted dive, continuing the roll back to level flight while always maintaining 1G (or close to 1G). Unless the passengers look out the window (or at night) they would not know the aircraft was being rolled and the stewardesses could continue to serve champagne.
