its not thrust or engine speed that makes the plane fly its the speed of which the air travels past it.
Or wind.

You'd need the engines turned on to create an equilibrium. It's a trick that some aircraft can do, mainly microlights. Not sure how well a 737 would do it

You sir, are an idiot.

Oh, and one final thing. Airspeed, not ground speed.

Planes use LIFT to fly, and if its on a conveyor belt, there will be no lift as the plane wont be moving. Just its wheels will move. Thus it wont take off.

The conveyor belt itself won't even play a part in the actual taking off of the plane, it will just be a materialistic spectator in the whole process.
The wheels on the plane can turn as many rotations as the conveyor belt wants it to, but will have no physical affect on the thrust/take off of the plane. deeeerr!

the plane pushes off the air not the floor. 'Conveyor runways' do not affect it in the slightest

If the plane is thrusting at 50mph, it will be moving at 50mph. The conveyor belt affects the wheels on the plane, which spin freely.
You can't slow a plane down by turnings its wheels faster than they're already going. The are not driven. The engines push air. If the engines push air, the plane moves. If the plane moves, it flies.

I believe I 'may' have been the first person to offer the argument of:-
'what would happen if a plane landed on a conveyor belt moving equally in the opposite direction?'
No doubt the retards on this thread will now once again flock in their herds to tell us the plane will stop dead on touchdown in that scenario

So if the plane landed with the conveyor going the opposite way?
As long as the reverse thrust was enough to slow the plane down (or the conveyor was long enough to allow this to happen) then it could stop and the wheels would free wheel on the conveyor.
Same would go if the conveyor was going in the same direction of the plane for that matter.

I think you miss my point Cosmo.
People who argue the plane wont take off will also have to argue that the plane will stop dead on touchdown (given their lack of understanding of the wheels not actually driving the plane in any way shape or form)

Ah my bad, yeah they would have to argue that point given their stance.
What would happen is the above though!

Fucking hell, I thought this was obvious, if a plane needs 100mph to take off, it will take off going forward 100mph.
If the conveyor belt is going backwards 100mph and the plane thrusts to its 100mph needed thrust, it will still go 100mph and take off. mmmkay.

anyway, if a plane can take off on a conveyour belt, why don't airports have them?

Hold on, which way is the conveyor going in relation to the plane?
I may have misunderstood the idea . . .

The conveyor is completely irrelevant to the situation. It is a red-herring as it has no net effect on the aircraft's ability to take off.
I would rather lose by a mile because i built my own car, than win by an inch because someone else built it for me.
