1. Auto takeoff
Take off in a tail wheel in game with out any con sessions is much harder then in real life. I have about 2k tail wheel hours. Other here do as wheel. In AH you get no seat of the pants feed back that is your primary sensor when flying tail wheel, or any aircraft when keeping the ball centered.
2nd why do you wish to make something that has almost 0 game play impact and remove it from players. After having taken off 1000's of time in game do you really think it adds fun for most people to have to do it manually? You may enjoy it, but for many people it would be nothing but an added nuisance.
2. Combat trim
Trim is a system that can not be simulated accurately with spring return to center controls like we use. With real controls you simply hold them where you want and move trim until there is no force left on the control. With spring return game controllers you must move stick and trim at the same time.
Many people seem to not understand how combat trim works. It is a simple table that at speed X trim position is set to y.
And you have not even started thinking about all the different controls users have from a mouse to full rudder pedals and hotas with knobs that can adjust trim.
3. HUD for for what should be read from one's own instruments like airspeed and altitude
The SA that the hud gives you is simply to assist in the loss of SA from flying on a flat computer screen. Flying vertical in real life does not take much to learn. Flying vertical in AH with out the hud is a PITA.
Now for your question, AH is a simulation who's primary purpose is to create a fun game that simulates WWII combat. Many skills learned in AH translate directly to the real world.
