Trick question

No because the wheels are free spinning and do not provide thrust. The struts and wheels merely hold the aircraft off of the ground. Free spinning wheels can’t keep an aircraft from moving forward. The wheels will simply spin faster.

So then why do planes have brakes?

maybe if the planes landed on a conveyor belt that would spin the opposite direction of the wheels at the same speed no brakes would be required. The plane would just instantly stop. makes perfect sense.

Exactly. It wouldn't prevent wheel slip and stop instantly same as it wouldn't prevent wheel slip and prevent take off

Or we could make runways shorter because we could just hold the brakes, full throttle and bam then the plane is floating.

Well you could do that, but you would need a longer runway, not shorter.
Oh and you'd need a way to re-tire in mid-air before you landed because those would be blown out and melted off the rims....unless you belly land on a conveyor belt that's spinning at the same speed in the same direction you're moving[emoji847]

Yes, however I think it would sit in the same spot until it reached a speed where lift can occur.

Interesting question and way to think about it.

Is Maverick the pilot?

The plane will still be pushed forward by the engines if they are powered up. This however should not allow the plane to fly because the treadmill is preventing it from gaining enough speed to have the wind it needs for lift. So no the plane will not fly.

This thread is like politics in this country.

Sometimes it’s hard to tell sarcasm in the comments. Are you serious?

[tvc184]

We still need a mathematician or an engineer to the determine that when the jet does takeoff, how fast will the runway conveyor be turning?

Sitting in the same spot would be a speed of zero mph

How? Do the wheels push the plane? No, they are just along for the ride.

I don't think it would because of the momentum pushing in the opposite direction not allowing the plane to move fwd fast enough to gain enough speed to catch flight.

you are on to something. You could cash in on this one.
