EDIT: ive offered to take a poll of 15 aerospace engineering professors, and even if one of them says the plane takes off, i would admit defeat...thoughts? [/ QUOTE ] That's me. Pay up. edit: I read fast and didn't see the word "professors".

Re: think about this...
I had to think about this for like fifteen minutes before I realized how stupid I was.
Patrick, Ray, et al. are clearly correct. The rotation of the wheels doesn't have a damn thing to do with the plane's velocity.

Re: think about this...
Tell me if this analogy makes sense:
I've got my daughter in a stroller going the wrong way on the moving walkway at the airport. I'm standing next to it on the ground, not on the walkway. I reach over and push the stroller hard enough that it moves forward relative to me. If the stroller had wings, there'd be lift. But at this point aren't the wheels moving faster than the walkway? Is this whole thing semantical?

Re: think about this...
pat, the only upward force experienced on a plane when its taking off is lift, and to produce lift, you need wind over an airfoil, in this case theres no wind, thats the simplest explanation anyone can offer

[ QUOTE ] You realize that in your OP, wheel speed = anything, plane speed = 0. Obv, if the plane isn't moving forward relative to the air, it doesn't take off. Unless, of course, your plan was to phrase a question with a clear answer, then try to confuse people so you would have a big thread. [/ QUOTE ] I've said this multiple times now - at no point in this thread did I say plane speed = zero. I suggest following Patrick's advice and creating a FBD. [/ QUOTE ] UHHHHHHHHHHH what is your point. Either the conveyor belt is moving exactly opposite of the plane or it is not. HOW is the plane moving? I would love to know, so I can throw my engineering degree in the trash.
