Can you explain how the conveyor has an effect on the thrust of the engines? The engines do not propel the wheels, they push against the air, therefore the plane will go forwards in relation to the air and the surrounding ground, and at double the speed in relation to the conveyor.
The conveyor velocity does not equal the engines velocity as they are not connected!
