You could possibly make it like Battlefield 1942. Hear me out, guys! When you land a spit or aircraft in that, if you taxi to a certain place, your ammo supplies are slowly replenished, so maybe we could do that. Land and taxi to a position and wait 1-2minutes for ammo to be restocked. But no healing an aircraft. Its too complex and a bit lame. Even better, wait 10 minutes for a full reload -- go make a cup of tea or something, and in online matches pray you don't get strafed!

--edit--
actually, that was just my suggestion, i've no idea if it can be done at all. I'm one of the great morons with no modding skills whatsoever! Ignorance is bliss, and i'm in awe of those who can!
