Contrary to Airbus SAS philosophy?

Hi,

Mr Optimistic

A 'big red button' which forced direct law, with direct law behaviour a set of memory items, would seem a reasonable last resort to offer a bemused crew.Not forgetting appropriate display of unusual trim conditions and cancellation of any warning cancellations, naturally.

Dificult to imagine a change in their minds to implement this (very reasonable) last resort. "Collision" of K.I.S.S. x K.I.C.S.

Complex Systems can deliver, at certain situations, Stupid outputs. Again the old "Testability issue" of Complex Systems.
