Can a jet on a treadmil fly?

[Renegade]

Look at my post prior to yours. As I pointed out, the original post is made by a NON-PILOT whose only flight experience is VIDEO GAMES.

He butchers the question and then jumps to a completely unrelated conclusion because he doesn't understand the context and purpose of the question.

Congratulations. You are the second person to actually read the OP/Link and see the questioned was butchered.

But we have moved past that butchering and are using a more general example:

This language from the original rec.aviation post I mentioned is better:

If a 747 is on a treadmill as long as the runway, going the same speed that the aircraft is going. Will it still take off?

[Renegade]

Once again, if it drifts backward, then that drift must be subtracted from the vector of the relative wind.

This is why general aviation has so many accidents....

So the thrust of a seaplane cannot overcome a slight current.

And you claim to be a pilot.

It's not a pilot problem, it's a Newtonian physics problem, Adrenaline_6 with a degree in Aeronautical Science is telling you the same thing as have others, plane flies...

Heavy jet driver here with almost 30 years of flying under my belt... Given the treadmill is as long as the standard runway for control purposes...

As long as the jet is not tied down/back and the wheel brakes are off, it will accelerate forward under it's own power. The wheels will spin faster than normal though. Regardless how fast the treadmill spins, the plane will accelerate to a certain point until the wheels explode... The maximum tire speed on most large transport category aircraft is 195 knots. Assuming the plane gained enough "air speed" to generate lift before the tires blow up, she'll fly.

The A/C is not under power and is drifting back due to small current. Thrust is applied, either the A/C moves forward despite the current, or it does not.

Overcoming the current of the water DOES NOT create relative wind. You're asserting (somehow) that a plane can lose forward velocity (due to drift) and then regain it as relative wind airflow. The air above the water is not moving with it (at least to any noticeable effect), therefore overcoming the drift does not add to lift. However much you drift backwards is lost in airflow and must be overcome. It's the same concept as landing with a tailwind, only in reverse.

THANK YOU! If you were not a dude I'd ask you to marry me at this point. Mind blowing how/why that's been so difficult for so many to fathom here, some claiming to be pilots. Ugh.

I cant wait till you post this puzzle again!

I think the example of the toy was helpful.

Let's say we have a toy jet with functioning engines...if we hold it in place on the TM & add thrust of say 100 knots, the TM doesn't turn. So, let's now speed up the TM to match the the travel of 100 knots to the wheels & then let it go.

First time using tappatalk and it's pita.ignore me

Never posted before and will never post it again though I find it interesting until some get condensending and obtuse about it.
