don't get me started. it's 2 am, I've been running around all day and I'm not in the mood....
ok, now I apologize in advance if I'm wrong but, if the conveyor belt is going the same speed as the plane taking off, then it will be staying in the same place, then there shouldnt be any air going over the wings to create lift..right? I'm still a student pilot aka noob.

That might not. If the rotor rpm was like 2400RPM and the turntable as at the same rpm in the opposite direction, then the helicopter would just spin around and the rotors would sit there. Correct me if I'm mistaken, but its a fundamentally different problem than the converyer BS.I stole this from someone here, sorry I cannot remember whom.
Gotta go with the noob here.....I stayed out of the debate last time. The show was just too ridiculous. The "ultralight" they used as an airplane takes off at slow speed and did not remain stationary as required. It got dragged by the "conveyor"...which produced airflow...which permitted it to fly.ok, now I apologize in advance if I'm wrong but, if the conveyor belt is going the same speed as the plane taking off, then it will be staying in the same place, then there shouldn't be any air going over the wings to create lift..right?

If you hold a kite while jogging on a treadmill......will it fly? Of course not. Drag the treadmill behind a truck, while jogging with the kite...yes it will fly.
All they did was drag the ultralite behind the truck on a rug. How about putting a plane on one of the automotive machines that spins the wheels while the vehicle is actually stationary and see if it will fly....guarateed not.
SteveC, request permission to borrow Picard face-palm picture.
did not remain stationary as required.
The problem does not state that the aircraft remains stationary. That's what the problem tricks you into assuming. An airplane has free-spinning wheels, so the conveyor is powerless to hold it in place. If your response to that is, "Well, if we don't assume that the aircraft remains stationary, then what's the point of the problem?" then our reply is: "There isn't one."cencal83406 said:The aircraft will be stationary
