my lame attempt at acting smart: h:

assuming negligible rotational static/kinetic friction/inertia/etc...
considing the following:

plane is stationary... conveyer belt moves backwards.
similar to pulling a tablecloch off a table with the contents remaining,

the plane will stay stationary and the wheels will spin along with the conveyor belt.

add in the thrust from the engines, and the plane will accelerate forward.

the wheels/conveyor are independent from the engine/air system
