A plane is standing on a runway that can move (only using some sort of conveyer belt). The plane moves in one direction, while the conveyer belt moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in the opposite direction).

Can the plane take off?

Interested to see what your thoughts maybe.

 

Yes

 

No

 

Due to a lack of moving air flowing over the wing, thus, creating no lift I'd say no.
It's the equivalent of a car creating downforce on a rolling road (except inverted), no air flow over the car, no downforce. There's a reason race cars, etc. are tested in wind tunnels, only difference with the plane is that you want the forces to be acting in the opposite direction. Now if you repeated the same exercise in a wind tunnel...

 

now as it does not state which plane it is what if i said it was a harrier jumpjet....

but i will point out i dont know the answer but its interesting to see what ideas you come up with heheh

 

And if you dont find out the answer you had better be hiding at the next meet

 

Yes

 

bloody hell stev and theres us thinking youn was going to tell us a very intelligent answer

 

Bugger!
And here was me thinking I was a bit clever for a change

 

 

The answer is YES

As the question was "can the plane take off"

You don't even have to turn the conveyor off

























The wheels on the bus go round and round

 

If the conveyer is moving, apply the brakes and if going forwards the plane takes off, if backwards then a big accident as it falls off said conveyer...
