Currently, we have normal and agressive AI mode. How about a new mode? Ally mode. This will make the spawned AI plane attacks other planes or ships that are hostile towards you. The marker on the allied AI will be blue and untargetable, just like the markers on a landing AI. The allied AI will fly around you, so it will be like an "escort" or something.
Now for the autopilot. We currently have Wing leveling mode. The new mode will be called "Attack mode" this mode will make the autopilot attacks planes or ships that have hostile status against you. The mode will be activated by pressing a designated keyboard button (Alt, maybe?) after activating autopilot.
