Ok after sitting in my captains quarters for a few hours I had an epiphany. I would not want AI to fly planes. For two reasons:
1.) plane AI would be unreliable and useless or they would be too good. Finding balance with AI is alot harder than finding balance with a player IMO.
2.) planes should be put in for the players enjoyment and the adding of another part of a crews tactics. Having AI fly planes, for me, would be like waving candy in front of a kid and saying you can never have it event though you can see it. Or like skyrims dragon born dlc where you could ride a dragon but its on rails and you never really get to fly it.
Plane idea: A plane with a pilot with a gun in the front and a gunner with a gun in a seat behind the pilot. The gunners gun is on a swivel that can turn in total 360 (with a safe zone of not shooting your plane of 210 degrees) you can move the gun 45 degrees up or 45 degrees down with a total of 90 degrees. This will require the pilot and gunner to communicate as well as the captain an the planes pilot to communicate for support, tactics, etc... Sorry if this was hard to read I'm on my phone right now and it's a lot harder than I thought
