Re: [Flightgear-devel] auto-coordination

[Torsten D. <To...@t3...>]

This is in fact my preferred solution.
- it does not break existing aircraft
- it keeps existing --enable-auto-coordination behavior
- it is configurable, even at runtime
- minimal code change

I have the patch ready and I'm about to commit it. While at it, I'd like 
to move the involved properties out of "/sim/" to "/controls".
/sim is so very much unstructured and a melting pot for properties that 
never found an appropriate location. And I think /controls just fits 
better than "don't know where, so put it in /sim". Objections?
I'll take care of the wrightFlyer1903, the pa22, the waveXtreme150, the 
Saitek X52 and the bintest protocol in FGDATA and adjust the names 
accordingly.
