Let's say you had a giant treadmill with an airplane on it

[ImbracableCrunk]

I don't get it. How is a treadmill supposed to take off?

Ok, look at it this way:

If you are holding a paper airplane and you are running down the street, if you are running fast enough when you let go (don't throw it, just let go) the plane will fly.
Now, if you're on a treadmill (or some frictionless surface) and running at the same speed, no forward motion, and you let go of the same airplane, it will fall straight to the ground.

go set your treadmill at its highest speed and jump on it....you will fly backwards, its pretty funny to watch. but seriously go run on a treadmill at any speed you wish get off and see if you went anywhere.....

seriously, don't get involved beyond ridicule.

I just can't help it. This is just beyond idiocy.

And that might actually be relevant if an airplane produced forward thrust through its wheels instead of a prop/jet.

I guess your correct if we are talking about a 3 thousand foot long treadmill.

That's exactly what we're talking about. From the original post:

the plane will fly. the prop will pull it along the treadmill and create the relative wind required to takeoff. the wheels have nothing to do with it, they will just be spinning faster at rotation.

 

[regionaltard]

So, you will not takeoff.

BZZZZZT! Thanks for playing.

I realize it was rather rude.

What proof do you have, Mr. RegionalTard?



Hmmm, I think your screenname here speaks for itself... at least the last four letters do.

Hey, no need to get nasty just because you are wrong!

The speed of the treadmill and the speed of the aircraft's wheels have nothing to do with it's airspeed. A plane moves due to thrust created from a prop or jet, totally independent from the ground. Where is the airspeed taken from? It's not from the wheels like a car, it is from a pitot tube. It will take off.

(I can't believe I even got involved in this one)

 

[ImbracableCrunk]

This is still going?

I'm still looking?

Must . . . poke. . . .eyes. . . out. . . .

Ok, fine, take this thread in a new direction.


Can I log airplane treadmill time as PIC?

If I'm flying a plane with 1000lb of Canaries, and they all get loose and are flying around inside the aircraft, does my gross weight decrese by 1000lb?

So as long as you ignore Newton's third law, then yes, your gross weight decreases
