In another thread we are discussing the resurgence of unrealistic defensive manuevers in the game, since 1.04 was released.
These are situations were extreme negative G manuevers are used repeatedly, or situations where someone "porpoises" an aircraft creating extreme positive G's, then negative G's, then positice G's, etc. The biggest reason that these are unrealistic, is that such manuevers would rapidly degrade the pilots ability to control the aircraft so he would be unable to continue such manuevers.
Also it is well known that the human body is much more sensitive to negative G's, than to positive G's.
So I would suggest we model Cumulative Pilot Fatigue.
Simply put, the more frequently a pilot performs high G manuvers (within a single sortie), the lower his tolerance to G's become and the longer it takes for him to recover from blackout/redout conditions. If the pilot spends several minutes not pulling these high G manuevers, his "resistance" to them would then slowly go back up. Of course it would take more time to come back up, than for it to go down.
This has a firm basis in human physiology, and would add alot of realism to the game, without artifically hampering flight models.
Model Human Limits, not just the Aircraft Limits!

FYI, AirWarrior has had this "feature" for many many years, and works quite well.
