Fire Control takes away the penalty to the pilot which almost all fighters have.
Irrelevant. The pilot needs to move the plane to make the cannon hit, the cannon is not moved independently from the airframe. We can argue over 21st Century semantics applied to XX century technology another time.
RAW does say the pilot has a -2 modifier when using fixed mounts or turrets pointing forward. That makes sense on anything that isn't a "fighter" which is how I would house rule that. As I mentioned above, Fire Control is going to negate that most if not all of the time in the "fighter" situation.
