Hum,
AOrg users are too smart....

Hum,
If we assume that there is air and that the aircraft uses jets  (or the propellers do not push air past the wings) the airspeed relative to the aircraft is zero.

The plane cannot takeoff.... (the answer in  av web.net is wrong!)

You canna change the laws of physics.

[blobrana]

Lol.
Took me less than a second to decide the correct answer is No.

It’s simple physics.

There is no forward motion. (It does not matter if it comes form wheels, jets, magnets or rubber bands etc)

No forward motion  = no air flow = no lift...

Hum,
whoops...
thinking about it further...the plane does move forward...
Assuming that the wheels have no or little friction.

And if it moves forward then there is air flow.

[blobrana]

LOL
me too...
My first thought was to add up the two (opposite) vectors to give zero speed.
But the ground vector is a red herring,  there is only one vector (the plane)

Doh!

Hum,
i hate
