^i agree that the speed of the ground under the plane has nothing to do with air speed, but doesn’t speed of the plane on the ground affect lift?..meaning if the plane is stationary relative to someone on the ground, the plane would have no velocity to generate lift with? for the plane to lift off, the conveyor ramp length is important in seeing if there’s enough length to generate enough lift through the plane?
