There is a plane (Boeing 777, prop plane, whatever) on a moving, conveyor-type runway. The runway moves in the opposite direction of the plane at the exact same speed as the plane's wheels. There is no wind. Can the plane take off?

What kind of plane?

noggindoc · #3 11-23-2005, 09:39 AM

depends...is the pilot stoned?

If there is no wind speed, there is no lift. OTOH, you could be facing a strong headwind. Insufficient data to answer your question.

Airspeed = 0 the plane cannot take off. This would be the same if the plane had a tail wind that was = to it's forward motion.

No

Good answer, but just seconds too slow. [img]/images/graemlins/grin.gif[/img]

edit:
I see Ray has altered the OP to provide some of the lacking information. My "insufficient information" answer was clearly the correct one. [img]/images/graemlins/wink.gif[/img]

so what's your answer? maybe it requires more thought than you're giving it credit for.
