I do believe the GV icon distance for airplanes should be extended, to 2 or 2.5K. Right now, by the time the icon appears, you are almost where you want to be releasing your bomb and pulling up, and almost within range for wirbels.
I think making dive-bombing slightly easier in this way would be better for "balancing" air and ground power in the MA than the current solution of allowing anyone who can vaguely fly a plane straight and shoot to up unlimited 37MM Il2s and strafe sitting-duck tanks.
