Eric, regarding the rough air speed - I thought you
flew an ASH 26? If so the BGA datasheet (quoting the
'FAA Web') lists the rough air speed as 99 knots i.e
the same as the manoeuvring speed. For my 2005 Discus
2cT the speeds are both 103 knots. I think all gliders
have a rough air speed limit for conditions such as
'wave rotor, thunderclouds, visible whirlwinds or when
crossing mountain ridges' to quote my manual.

You're right, John - I should've checked my manual. Does anyone know how
the Rough Air limit is determined? Is it always the same as the
maneuvering speed limit in gliders? It's been a long time, but I recall
the rough air limit being different (significantly higher) than the
maneuvering speed for my Std Cirrus.
