Define "move".

The wheels may counteract and spin in the opposite axial direction and thus they will "move" but my thoughts are since they cancel each others linear "move"ment out, then technically this is a trick question, cause the plane is not "moving" as most people think of as moving.

When I think of a car "moving" it's displacement is constantly changing. Down the highway. But who's to say that same car on my dyno is not "moving". It's not moving linearly, but the wheels are moving axially.
