My Wish list:
Aircraft to be added somehow either as static or AI:
U-2, SR-71, EC / RC 135, AN-2 Colt AI flyable, and other Soviet Bloc Prop aircraft from same time period.
On the ground:
More airfield ancillary gear IE Tow bars, steps etc, hopefully FCS heater's Mod as well, complete with the cloth target. Better lighting at ALL Airfields at night
Skins:
Better skins on various aircraft especially the C-17, a Medic marked Helicopter for primary countries, USA, Russia, Ukraine, Israel.
Camouflage skins on CH-53, UH-60, C-47
Other stuff:
The guns mounted on UH-60, C-47 actually fire if landing in a hostile environment, say within a 1/2 mile radius.
Ships:
Reworking of the skins on the Vinson and the Kuznetsov ( to look older and more used) with the ability to have a crew working in or around aircraft. Static aircraft allowed to park on both carriers.
And of course the satellite viewer back for better positioning when making missions
Thats all I can think of right now, will update
