It's curious that the FBW debate always seems to come down to the alpha protection law on Airbuses - I, as with my fellow mad-man above, can see no useful activity in the post-stall regime.
Almost never mentioned is the prescence of a full authority FBW type system on all modern large transports and many small ones - the FADEC. This has
absolute authority over the thrust you can get from the engine - you'll never be able to firewall a FADEC engine.
One of our types has instructions to push the throttles fully forward during windshear escape; on the older aircraft, that means busting the TOGA rating and getting a significant thrust increase, on the newer aircraft you just get TOGA (APR technically). That would seem to be a case where the automatic limits are a potential degradation in safety, yet
AFAIK every FADEC engine does the same, whichever aircraft its fitted to.
A 20% boost in thrust when you
really need it would seem to be of more interest than the theoretical possibility of a harried line pilot somehow managing to fly within 0.1 degree of the stall in an emergency.
