Possible effects of this, if possible:
Fighters that land are not affected by anti-air fire
Droid fighters: When airborne they have an attack power of 100% against air units, less against ground units. When they're walking on the ground (yes, they can do that :p) they have a really low attack power against air units, but kick butt against ground units.
List of potential places to appear in the game where landed ships would be useful:
Falcon on Tatooine during ANH.
Falcon on Hoth during the Battle of Hoth
Medium Transports on Hoth during the Battle of Hoth.
Dagobahn Eagle
