(either through wind or a big **** off turbine) air over the wings or on a still day moving the wings forward in relation to a fixed point on the ground at 25mph. Agreed?If the aircraft is to apply EXACTLY THE SAME AMOUNT OF THRUST it required to JUST make this speed
Profanity, caps and bold text - engaged.
Move this thread to Rage Speed 4, Scotty.
Everyone is right. Yeh hey!
Normal conditions - Plane applies a smidgen more thrust and takes off. Whoop.
Magic superpowerful speed matching treadmill - shakes plane to pieces
Ignoring rules of reality but obeying certain rules of physics - friction in the wheels matches the max thrust of the plane and it doesn't take off.
End of thread!
Wheels are attached to planes. If you park a plane by putting the brakes on, and then throttle the engine up, the plane will not move.
Yes but on a conveyor belt putting the brakes on will allow the thrust from the engine to act on the conveyor belt, driving it forwards and allowing air to move over the wings, so allowing the plane to take off.
If you want to take off on a conveyor belt put your wheel brakes on...didn't we do this 240,000,000 posts ago?
Methinks you may have "direction of travel" or "troll" issues there gwaelod,

No mun...not if the conveyor belt is freewheeling and so isn't being driven by some sort of force outside of the Plane/Conveyor/Atmosphere system
Why would the conveyor belt / treadmill be freewheeling??
It's driven. By a motor. In the opposite direction to the plane.
Is it???
I think I have had a fundamental misunderstanding of this all the way through..I always assumed the conveyor belt was freewheeling
Hence the "trolling" post.
doh

Not another one 
Not that it matters, but it would also take off just fine from a freewheeling belt (without needing to use the brakes) for pretty much exactly the same reasons.
Let's broaden this debate into the Bernoulli effect and the disagreement over its influence on airodynamic lift.... What makes the wing fly?
Carry on.....
What makes the wing fly?
Having a conveyor belt underneath it?
