Aerial dodging: Add Int modifier to aircraft's AC
Swift shooter: Reload as a free action, rather than as a move-equivalent. This allows more than one attack per round, if the firer is capable of doing so (ie: BAB is +6 or higher).
Expert targeting: Add Int modifier to damage when using aircraft mounted weaponry.
Evasion and improved evasion: as rogue abilities. In summary, evasion allows no damage on a successful reflex save, while improved evasion allows half damage on a failed save and none on a sccessful save.
Raking strafe: extra damage when behind or flanking a target, like the rogue's sneak attack.
Smooth shot: No chance of weapon jamming.
Bonus feat: as per fighter, and restricted to be from the fighter list.
Defensive dive: Same as defensive roll of the rogue class. In summary, any attack which would reduce the aircraft to 0 hit points or less allows a reflex save for half damage.
Critical shot: Study victim for 3 passes, then make a sneak attack that successfully deals damage, the attack has a chance of slowing the target and reducing it's MC. On success, target's speed is reduced by 50% and MC is reduced by one class. Note that only this gunner need study the victim without attacking, any other gunners may continue to act as normal.
