only in alternate direct law...
Thank you for your answer (except when you tell me the speed I quote 250 is incorrect...let us not split hairs, if it is 249 or 251, we are talking here of exceeding or not 250 knots at low altitudes)
There is something that escapes you, it seems to me. In alternate direct law ONLY, you have to respect the manoeuver speed by applying careful inputs on the stick.You are right there.
In normal law, do you believe for one moment that such a sophisticated airplane will let you violate the manoeuver speed and give you 25° deflection of ailerons at 300 knots? In normal law the plane looks after itself,, as flight control normal laws (I quote) covers "alleviation of manoeuver loads". Sorry to disagree with you on that subject, I remember au French BEA report, about a near midair where an A320 was implicated, and which said that due to its speed of 250 the pilot was able to fully deflect ailerons and spoilers. I shall try to find it, if you are interested.
