final glide estimates

That does not apply to gliders under JAR22. At manoeuvering spped, you may
apply a full deflection of either aileron, rudder or elevator without
causing structural damage (but as Bill pointed out, not two of them).

Maneuvering speed only relates to a limiting speed for wing protection
in a positive mode. Therefore, any full deflection of controls, other
than the elevator in a stick back mode, could result in failure of the
airframe. Also, since the wing is the only surface defined under
maneuvering speed, there could be a possible failure of elevator,
ailerons, fuselage, etc. with abrupt deflections.
