    Good conjecture. 
    Very true. The 1 G stall speed remains the same, whether
the aircraft is straight and level, or whether it is in a
60 or 90 degree bank. Stalls at higher Gs are usually, if
not always, referred to as "accelerated" stalls, and, of
course, that speed also remains constant regardless of the
bank angle. For example, if the accelerated stall speed
is, say, 60 knots at 2 Gs, it will be 60 knots at 2 Gs for
all bank angles.
    We were taught to avoid using high bank angles and to
go around rather than try to salvage a final turn overshoot.
The reason is that the student pilot was unaware of the fact
that the higher bank angle required in salvaging the overshoot
also required pulling more Gs, which could result in an
accelerated stall, and possible loss of control of the aircraft.
    I read, somewhere, that ALL aircraft will pull 2 Gs in
a 60 degree bank, regardless of speed, if level flight was
maintained. I found that hard to believe, but confirmed it
in both the jet aircraft and the light aircraft.
