Other mistake: The beginning footage shows the USS Roosevelt CVN 71 as the carrier being used for flight ops, yet they refer to it in the movie as the USS Lincoln, CVN 72.
Other mistake: The only export customer for the Tomcat was Iran. But the "fifth gen" enemy fighters were PAK FA (Sukhoi T-50 / Su-57) which are flown only by Russia.
Other mistake: During the training scenes, aviators are told to keep a 500 to a 1000 ft safety bubble around them at all times. In multiple scenes you can see where they are almost flying in a wingtip formation.
