..........everything I have read says that bellow Va FULL use of flight control is permitted without overstressing the airframe.
Va relates to wing stall before overstressing of said wing. It certainly does
not include the use of full rudder.
If Va included full rudder useage at wing stall, then you'd be authorising
FLICK ROLLS, on any aeroplane, provided you're at or below Va !
If that's your interpretation, then please let me know which airline you fly for and I'll avoid it ! (only joking).
I just could'nt let that one go, sorry if it's off-thread.
(Fundamentally, we need to agree here that full rudder useage is'nt something that's necessarily permitted or necessary, except for single engined operation and (in an extreme case) landing.
Fins are "easily" overstressed.)
