Top Gun came out in 1986. Meaning that in the sequel, Mav's been retired from the Navy for 15 years and is now flying 767's full of rubber dog shit out of Hong Kong for Fedex.
Deceleration is negative acceleration. Acceleration was still positive but the amount went down.When the high acceleration of the catapult stops at the end of it's travelthe acceleration drops to just that of the jet engines producing the negativejerk motion (head forward).Even though the velocity and acceleration are still positive the jerk is negative.
The first two are correct.The third is not.Also Kirby is strangely quiet on this one.
ok. thanks.
When you are no longer accelerating you are no longer GAINING speed. Immediately after leaving the cat you will NOT be accelerating until the jet engine gains enough thrust to overcome the mass of the plane and cause the speed of the plane to increase. Until that time the plane is decelerating and the pilot experiences negative G's.

Utter garbage..The engine is at full power from the moment the pilot gives the go signal.Even though it is not capable of accelerating the a/c to the degree of the cat, it is still producing thrust. As the cat releases, the engine does not suddenly think “ jeez, it’s my go now..!”If we arbitrarily said that 80% of the acceleration was provided by the cat and 20% by the jets, that would mean that the acc’n would diminish dramatically upon release, but not completely.Do you think if the cat launched the jet without the engines running, that it would accelerate at the same rate ?No.You are of course correct that it’s simple really, but you need to re think...really.Let’s try a cave man explanation.If there are three people each capable of trying to push you out of a doorway, and you are resisting them. They will easily win the battle, but if two suddenly stop, you will not momentarily stop moving because even one can still overcome your resistance.Remember also, that some of these jets have the thrust to be able to accelerate vertically, so the argument that you need to wait for the thrust to overcome the mass is infantile.
A trifle harsh
Are you really arguing the physics of being catapulted off an aircraft carrier from you computer keyboard? How about finding someone that's DONE it and ask them?
Come on,it's a movie.I'll go, and see some bad ass shots of jet fighters on the big screen. I saw the first one in a theater and it was cool back then. "high way to the danger zone"
Believe it or don't. At the three second mark and at the 3:48 mark both pilots are subjected to the same phenomena. https://www.youtube.com/watch?v=Nj9D1Ls-_JM Paul B
I like turtles
Case closed. Pass the popcorn
If the pilot braces his head against a given acceleration and that acceleration suddenly halves, his neck muscles will push his head forward before he has time to react.
Thank you and goodnight
4)when the catapult finally disengages, the airplane pitches up, quickly, just as you'd expect it would (even if it overall sinks downward at times).5)when the airplane pitches up, the pilot will pitch forward (relative to his cockpit).
Where were you at the start Daniel ?
The pitching of the jet has rotated the headrest away from the pilot’s head
…a topic concerning the lack of physics accuracy in movies?It’s a moving reference system that the pilot is part of. The cockpit is subjected to a pitching rotation and the pilot’s head isn’t keeping up. The pilot will feel his seat pull away from him, while he is firmly strapped to that same seat.The effect is more pronounced than during flight since the pitching rotation on release is about the main gear contact point (well below the pilot) and not about the c.g. of the airplane (closer to the pilot).
