No it is not irrelevant Unscimes. It is the most relevant issue for me.By Unscimes. This is all very interesting, although irrelevant to the original question posed by Zeus.
Although as you have stated that the wheels are freewheeling, and are not mechanically attached to anything, I assume that under the original question, you now accept that the plane will take off.
Is this true - are you now a 'flier'?
And are you now working on a different problem?
Is the plane allowed to move forward? Yes or No?
If yes - then the conveyer doesn´t have a tracking system that tracks the aircrafts speed and negates it.
Yes the distance is irrelevant Jez. I agree. But the original question indicates that the aircraft wont move forward as it´s speed is negated by the control system.By Jez. The distance is irrelevant, it could be half a mile or 20 miles, it was just as an example to give perspective.
I realise I am repeating myself now - but please, please tell me you understand what i´m saying.
