Right...well the treadmill tracks the movement of the aircraft's fuselage...and adjusts its speed to cancel out all forward movement of the aircraft's fuselage...however fast it has to go to do so.
By "speed of the aircraft" I am referring to the forward movement of the aircraft's fuselage...not the speed of the wheels.That's my definition of speed of the aircraft too.

Why do you think that an aircraft's speed can be canceled or otherwise influenced simply by applying force to its free-wheeling wheels??

Yup.........pretty simple really but some folks can't seem to fathum it quite yet. Plane at, say, 100 knots forward, treadmill at 100 knots reverse, airplane wheels spinning at 200knots but airplane still moving forward at 100 knots...airplane goes for a ride in the sky
OMG...are we really doing this again?!?!?!?!?
Looks like it.
Looks like it.
some thick skulls around...LOL
can't beleive how some people will argue a point so strongly that they don't understand. If an airplane is flying at 100mph ags and picks up a 100 mph tail wind will it keep flying?:idea:

case closed!!!
Will this simplify it enough for those who don't get it:idea: You need to be able to visualize things. Lets say the treadmill is the length of the runway.
The plane is setting on it. Even if the plane was setting still ( tied to something not on the treadmill) and the treadmill was at 100 MPH the wheels would be moving freely spinning at 100MPH. When the thrust is applied with a prop or jet the plane will accelerate forward. The tread mill could spin twice as fast and the only thing that will notice are the wheels on the landing gear.
No it will not fly, I tried it yesterday.
