Avoiding Vne

no they dont, they have to fail progressivly. no glider
would be alowed in the air by any regulating body if
a wing could break in a 1000th of a second. i dont
think you really understand the force that would be
needed to do that. the instantanious g-load to do that
would kill you out right.

Another dangerous misconception :-(((

If the actual extreme load is 6 g, the glider will loose wings as soon
as G-loading is greater than 6 g. Not 5 seconds later, not 0.5 second
later, but immediately. And not "progressively" (can you loose wings
progressively ???)

And in a modern ship near VNE, a small stick input may bring you from 1
to 6 G in less than 1 second.

Hence there is no chance at all that black-out or grey-out warn the
pilot of a too high G-load in an emergency situation.

You may have plenty of spin training on an ASK 13, it's better than
none, it will not prevent you to getting in a dangerous situation with
an open class glider. Spin training in these is prohibited, but high
speed flying is not : everybody should train to fly at higher and higher
speeds up to VNE in order to get used to the very high sensitivity of
most modern gliders at high speeds and to master the technique to use
only very small control inputs (including putting their hand firmly on
their leg to prevent unwanted or G-induced stick movements)

Q. Pourquoi ne faut-il pas répondre au-dessus de la question ?

Yes - on some gliders anyway. The Schweizer 1-34 is designed so that the
*first* failure occurs about 2/3 out from the root at about 8 Gs.
