Tanto per dare una idea al "pilot side", questo è ciò che recita l'FCOM di una macchina CS25 (AT75) riguardo la VA e i rudder inputs.
"Full application of roll and yaw controls as well as maneuvers involving angles of attack near the stall should be confined to speeds below VA
Caution
Rapidly alternating large rudder applications in combination
with large sideslip angles may result in structural failure at any
speed"
Di coneguenza mi viene da pensare che i limiti strutturali che avete riportato siano validi solo per una escursione continua, non ad una alternata, giusto?
CS 25.301 (a) Strength requirements are specified in terms of limit loads (the maximum loads to be expected in service) and ultimate loads (limit loads multiplied by prescribed factors of safety).
CS 25.303 Unless otherwise specified, a factor of safety of 1·5 must be applied to the prescribed limit load which
are considered external loads on the structure
