Firstly, may I say how polite and good humoured this thread has been.
But I guess we all know the score. So far we have been discussing real life flight dynamics. But we all know that 'our' aircraft are but virtual objects inside a computer - or computers. Virtual objects have no substance, so no inertia. Normally we affect the vectors (speed and direction) of these objects through our controls. The controls send information to the program and the program says, 'well, if you are doing that to this particular virtual airplane, the result is this.'
But if we could bypass those controls and send instructions directly we could perhaps - and I am a bit out of my depth here because I am not a professional programmer - send a few lines of code that would effectively say:
1. Ignore normal control inputs.
2. New heading = old heading plus 180 degrees.
3. New speed = old speed x 2
3. Execute.
4. Resume reading normal control inputs.
Just a little macro that could be mapped to a single key.
Am I saying this is done? Well, I'm pretty sure it is possible (very, very happy to be corrected by an acredited expert on that) and if anything that is possible, usually comes to pass one way or another. Only by a tiny minority, of course, whose thinking I personally do not understand.
Am I upset about it? Nope. It happens much less than 1% if the time and I would be silly to let that affect my enjoyment
