With regard to the original message,

I don't think Derek is arguing specifically that the effectiveness of the
elevator depends on the angle of bank, rather that pulling back on the stick
with the wings level or in a shallow bank leads to a nose high attitude from
which the glider will slow down and stall. In a steeply banked turn, pulling
back on the stick tightens the turn more than it raises the nose so you
won't slow the glider down very much, any pre-stall buffet is more likely to
be the result of stall speed increasing with higher g.

Its easier to reach that pre-stall buffet (inadvertently or otherwise) by
slowing down than by pulling g, thus it is easier to use the elevator to
stall a glider from straight flight or in a gentle turn than in a steep
bank. Either way, the recovery is the same, ease the stick forward.

If your instructor asks you why its harder to stall a glider in a steep bank
and you reply that the extra g makes the glider nose heavy, you are liable
to get a few demonstrations as to why that isn't true. The reason why its
hard to stall in a 60 degree bank is not because the glider is nose heavy
but because you are using virtually all the elevator authority to make it
nose heavy.

I'm sure its not what Bill meant to suggest, but its important that you
understand that just because you're pulling 2g, the glider is not too nose
heavy to stall.

Ed
