Mike,
I don't know if it will help, but you may find some guidence in part 23.1505
and 23.335. I started to read through it and the only thing I ended up with
was a headache.

Thanks, it does. The question of what the red mark on powered airplanes
means remains. Is it Vne at the aircraft's ceiling? If it is Vne at sea
level then there should be some language in the flight manual warning of
this.

The reference to low temperatures is also interesting. Is the strength of
the glider's resin reduced at low temperatures?
