Bah!
Only 4?
I have 8 man fighters. Commander, Pilot, Gunner, Loader, Engineer, Sensors (x2), Comms. Admittedly its in 60-90 dTon AWACS craft.
As for one man fighters... well, that I tweak as well. When the bridge is less then 4dTon its a one man fighter, with facilities for only one person. Only really valid for sub-20dTon craft. At 10dTon the extra 2 dTon help in making a worthwhile craft.
Actually answering the original question, yes the feat to fly fighters is Vehicle Proficiency (Ships Boat).
