I still don't get it, sorry.
Intended or unintended, applying full controls below Va
is allowed, according to all FAR, JAR or whatever you wish...
"VA – the calibrated design maneuvering airspeed. This
is the maximum speed at which the limit load can be
imposed (either by gusts or full deflection of the control
surfaces) without causing structural damage."

PILOT’S HANDBOOK
of Aeronautical Knowledge
2003 (FAA-H-8083-25), page 9-19.
So just to satisfy my curiosity:
What is the Va for Airbus 300-600 ?
