ffs, a plane could probably take off if it had no wheels and skis on the bottom for example, why cant people grasp its the fucking engines that move the plane forward

Am i wrong in thinking that if the conveyor belt was moving backward at the same speed as the plane would be trying to move forward at then it wouldnt take off because it would then become stationary?
Have we to assume that the conveyor belt is not moving at the same speed but slower? And therefore the plane would eventually take off?

No, the belt would have to be travelling at a massive amount of speed to create enough drag on the wheels to prevent the thrust of the engines overcoming the backward motion of the belt.

so what ur saying is the wheels might as well not be there? in theory..
Because its not like in a car where the wheels "push" the ground behind them

its the engines that are doing the pushing and it has nothing to do with what the plane is standing on..?

pretty much, yeah.
the wheels do slow the plane down, from friction, but not dramatically enough to counteract the power of the engines.

this thread is fukin stupid, IF it was on a conveyor, yes the fukin huge engines would make the plane power forward and the plane take off, people on cs bite so fucking easily when u wind them up, ur like fukin children

IIRC planes' wheels are free rolling so there isn't much friction
The conveyor belt could be going 5 times as fast as the plane, and the plane would still take off.
Newton's 3rd law of motion cannot apply in this case because the force for the engine is provided by the air thrust (as stated above) instead of the wheels touching the belt

What if the plane had propellers?

Cumberland thrust effect, will give more thrust only momentarily before they disintegrated, but the leftover grease will oil the blades and lets it slip through the air quicker

The way i see it, it would take off. I cant even see the conveyor belt making any noticable differance what-so-ever.
If you picture a small toy car on a conveyor belt. Your hand pushing it is the same as the thrust from the aircrafts engines. Do you really think if you apply a little force on the car, it wont move because of the belt? Of course it will, all the belt will do is make the wheels turn at a much faster rate.

Heathrow, 2.4 miles long
the longest runway in commercial use globally is only 3 miles long...
Longest runway in the world is Groom Lake, at 5.1miles long

it wont take off. the wheels would explode long before the aircraft reaches V1

but that plane was moving before it hit the conveyor belt....its meant to be standing on it!
