Another thought on the subject. If you look at JAR 25.331 on Flight manoeuvre and gust conditions, only manoeuvre in the pitching plane is considered. Again in JAR 25.333 the Flight manoeuvering envelope considers the “V-n diagram” the emphasis is on the pitching plane. Although a rolling limit is imposed it is not the rolling forces that are being considered but the asymmetric loading of the wings during a pitch manoeuvre with bank on.
Considering the accident with American Airlines Airbus A300-600R Flight 587 (facts available on the NTSB web site) perhaps we are flawed in our conventional thinking that VA is the design manoeuvering speed for all the controls.
Reading JAR 25.335 on Design Airspeeds carefully, the wording appears to imply the full application of elevator only.
Perhaps this accident has highlighted the folly of assuming that VA includes all the aerodynamic controls. If so, a radical change is needed in our training ,to “re-program” generations of pilots, to ensure the next accident is not because some poor mis-informed pilot has applied full aileron well within VA , only to find the last round of applause was his wings clapping hand behind his back!
