Again, you have changed it. The conveyor matches the speed in the opposite direction. The aircraft can NOT move forward at a greater rate - the conveyor will match it. It cannot move forward at ALL.

The airspeed is 0.[/b]
Just because the conveyor matches the planes speed does not mean that the plane is stationary. I have changed nothing. No matter how fast the conveyor spins, as long as the prop is pushing air it will move forward.

::ETA:: The key is greater friction with the air (caused by the prop/jet turbine pushing air) than friction with the conveyor.
