But anyway, it should be easier to do this - for example in settings before starting a campaign mission. Or perhaps, to increase the "immersion", the player should be able to talk with his mechanic before flight and tell him what features he expects from his aircraft in a particular mission.
Wouldn't it be cool? The animated pilot says to the animated mechanic "I wan't more of them tracers today, John", and he answers "yes sir, will do!". And the loadout is saved.
