Factual error: In all sequences where Maverick "puts on the brakes", he is shown pushing the throttle quadrant forward and pulling the stick back. This would put him in a full-afterburner climb, but you don't really stop and it doesn't work in a medium speed tail chase (which is easier to film). The air brake does effectively nothing on the F-14 because it is too small, and not deployable at full power.
Character mistake: In the opening scene is a paragraph describing why the Top Gun school was started. The word "insure" is used when the word should have been "ensure". They wanted to guarantee the U.S. had superior pilots, not take out an insurance policy.imshiffman
Deliberate mistake: In the shot where the F-14 and F5 canopies are only 3-feet apart, you can see that the writing on the side of MAVs F-14 is backwards. Also, if the F-14 was inverted, with the sun more-or-less above, its cockpit would be in shadow, not with sunlight on the nose, as seen. (00:08:55)
Factual error: During the briefing before the final scene, the Commander says, "The Migs carry the Exocet missile. They can fire that missile from a hundred miles away." Yes they could fire the Exocet from a hundred miles away, but the Exocet's maximum range at the time of this movie was around 40 miles. Plus the Exocet is a French missile and would not be on a Soviet Union fighter.
Factual error: The final dogfight scene has a huge error when Hollywood's jet is hit with a missile and he ejects. The next scene shows him manually deploying a small pilot chute to open his main parachute. After seat/man seperation, the main chute automatically deploys depending on altitude and airspeed. He would still be connected to his ejection seat until his chute deploys. Having to manually throw a "pilot chute" to the wind would leave too much for human error.
Factual error: All the scenes with actors in the cockpit were shot in the front cockpit. Pay attention to the canopy frame behind the RIO. This would also explain a large gaffe from the movie - Merlin taps on the fuel quantity indicator and exclaims "C'mon Cougar, we gotta land this thing, we are way low on gas." The particular fuel quantity indicator shown being tapped by 'Merlin' the RIO, the one with the vertical tapes, is present only in the pilot cockpit. The F-14A rear cockpit has only a small fuel totalizer.
