Aero drone (Batman: Arkham Knight)

If this is a drone, then you need to plan on it from above and press "X" in time (or RMB, depending on what you are playing on). Batman will then apply an explosive gel on him and jump off. Then you need to point the camera at the pilot and blow up the gel. And there are also helicopters, they managed to be shot down from the Batmobile, but they reappear after the game is reloaded, probably a bug.

how to destroy an aero drone??
Another way: you shoot from the "Destructor" at the drone's weapon and expose yourself to its shot - it explodes.
