Avoiding Vne

I'm sure everyone agrees the best advice is not to
get into a situation where you have to choose between
Vne and the G-limit. Thinking ahead with respect to
attitude and configuration as you initiate recovery
is your best bet.

if you get to this point you are in a world of hurt
anyway so the amount of over-G versus over-Vne is subject
to your personal risk profile.

I agree with all Andy said. I would add that "pulling as hard as
required to avoid VNE" is easier to say that to do, because :

- it is impossible, if you are not an experimented glider aerobatics
pilot, to know how many g's you need to avoid exceeding VNE,

- depending on dive angle and speed, it may be just impossible to avoid
VNE without airbrakes, even if pulling 15 g's (supposing the wings have
not briken before)

- it is impossible without a g-meter to know if you pull 5 g (or just a
little more, comprised in the "safety margin"), or 10 g's or more.
Especially at high speeds, because a very small stick input may result
in high g's, or pilot induced oscillation, etc.

And, last but not least, if you have been above VNE and lucky enough not
to have encountered flutter, you are lucky andy the glider is still safe.

If you have pulled too many g's and the wings have not broken, you are
lucky but the *glider structure may have been damaged* and you, or
another pilot, may encounter a catastrophic failure in a subsequent
flight within the certificated flight enveloppe !
