SNS3guppy,
You write, "Eurocontrol is not the be-all and end-all of RVSM airspace, and the world is somewhat bigger than Europe."
Quite correct. I thought you were from Europe so please accept my apology.
My flying has taken me all around the world but lets concentrate on your home, the USA. In a recent search of the FARs I have been unable to find a section that requires the use of the autopilot in RVSM airspace.
I always look for opportunities to learn from others so if you can direct me to the appropriate section I would be indebted to you.
best regards,
Bruce Waddington
