I think you better do a little more research on lift.

No, I know how it works. I was simply using the leading edge of the wings as a reference. Downforce on top, lift on the bottom.

how will the conveyor even start to rotate if the plane has not even moved forward, explain that one to me??

It won't. I know that.

I agree that is one reason, the other is that it would create alot of havoc during landing w/out them...

And a lot of unneccesary work for me, haha.

It will hit that speed..

Let us look at this way, say you put a bicycle on a treadmill, and you push it forward and the treadmill begans to speed up at the same rate as the tires, not at the rate you are pushing it. With this concept are you stating that you will not be able to push the bike off the treadmill pushing forward????

But isn't that the whole point of the argument? To see if an a/c will take off while the surface the wheels rest on move in the opposite direction at the same speed, aka, being stationary? If that is not the point of the argument, or there is some other factor that hasn't come clear, then I have been arguing for the wrong side.

I think 5 years in the Marine Corps working on the flight line troubleshooting F-18 fighter jets maybe makes me a little bit qualified here. Not just watching them take off and land like you and listening to other people who have no clue as to what the fuck they are talking about...

Enough said,, probally not let's hear it...

Not saying you're unqualified, or saying that I'm overqualified. And I do more than just watch them take off. I work flightline as well. I'm a structural mechanic, aerodynamic smoothness and structural integrity for the a/c is a critical part of my job.

i spent an hour last night explaining it to him as well. Peter, you have been owned accept your defeat and raise the white flag and run.

Not admitting defeat quite yet, I think I missed something, check bold print in my last post.

I realize that an Aircraft Carrier doesn't move very fast, but a plane could easily take off from that without any adverse effects...

the wheels could spin 2000000000000000000000000000 miles an hour BACKWARDS and it will not be enough to keep the 90,000 lbs of thrust from pushing the piece of sheetmetal that is a plane forward. the wheels are a BEARING doing nothing but reducing friction.

The point is it doesn't matter if the wheels are at rest, spinning forward or spinning backwards, so long as the plane is moving forward in relation to the ground it will take off....and a conveyor belt will not stop it from doing so if it is pushing on the free spinning wheels which have no affect on if the plane can move regardless. What you are failing to see is that the aircraft IS NOT STATIONARY, it is being propelled forward (in reference to the ground) via prop or jet turbine (or any sort of forward propulsion mechanism) and the conveyor is moving at the same speed backwards thereby causing the wheels to spin twice as fast which has ZERO affect on the planes ability to move forward.

Now think about this, can a float plane (airplane with water landing gear) take off against the current? The answer is yes, so long as it can overcome the friction of the water.

It just clicked in my head, for some odd reason.

I think as I kept reading you and xjhead posts, and completely removed the wheels from the equation, it makes total sense.

:icon_salut: to you and xjhead. I retract most of my statements from earlier.

Gotta get used to a new sleep pattern for weekend standy. Trying to, at least.

I normally work 1500-2359, but I've got standby this weekend. Show time is 3 hrs prior, so I gotta be in at 0300.

EDIT: Hope you (and all other Vets on here) have a good Veteran's Day. Drink a couple beers for me since I gotta stay sober. :icon_thumright:
