It can be a module on weapon slot. Right-click to enable it, then the aircraft climbs to y>=100 where few blocks can generate here. The aircraft then go straightforward unless there are blocks ahead, and will keep away from them.

If right-clicked with a map in hand, the aircraft will try to move towards the center position of that map. It'll hover / circle here and alert on arrival. Optional: If single-player / alone on server and the destination is far enough, the pilot may take a nap to skip the night and arrive in the morning.
