The plane's propulsion is pushing against the air, not the ground.


But to take off its True Airspeed has to match its TakeOff speed....
Quote
True airspeed (TAS) is the speed of an aircraft relative to the airmass in which it flies, i.e. the magnitude of the vector difference of the velocity of the aircraft and the velocity of the air. Under zero wind conditions and in horizontal flight, this is equal to the speed over the ground. Under wind conditions an estimation of the wind is used to make a windspeed vector calculation that computes an estimated ground speed from the true air speed and a wind correction angle to maintain the desired ground track.

It will actually MOVE foward on the treadmill against the direction even though the treadmill is going backards, and create airspeed


No - the riddle says - "This conveyor has a control system that tracks the plane's speed and tunes the speed of the conveyor to be exactly the same (butin the opposite direction) instantly."

The plane would need sufficient air speed to lift off, and thats irrelevant to ground speed


To get to sufficient air speed the plane needs to move through linear space for air to pass over the wing (assuming no wind) If the conveyor negates any forward movement of the plane it is not moving through space. The engines are producing thrust, but the conveyor is the one consuming this work - not the plane.

Think about it.....If the plane is not strapped down it will roll forward


ARGHHHHHHHHHHHHHH! How can it move forward if the forward movement is matched with equal and opposite movement from the conveyor??

I have 20HRS solo time. So you can't argue with me <img src="/forums/images/graemlins/lol.gif" alt="" />
