Now, to know if one simple (guarded) push button should be installed in the FBW Airbus in order to easily go back to the basic DIRECT LAW ... why not ?
Because pilots have their performance and limitations, too. If a pilot is so confused and behind the aeroplane that he allows it to enter protection, then he might start panicking and cut-out the protection that's doing it's job in mistaken belief that it's gone beserk. Mind you: no FBW protected aeroplane, be it Boeing, Airbus, Tupolev or Embraer, has been lost to stall or spiral dive in everyday operation yet. And protections are far easier to implement and more effective if you have FBW than classic controls.
That is not to say that protection makes anyone & his dog able to fly an Airbus. Staying out of protections still demands skill, concentration and foretought. And very seldom something goes seriously wrong and one ends up in altn or direct law and then Airbus needs the pilot at the controls as much as DC-3 needs it.
That is
why:
I suggested a change in the software/logics of the use of the instinctive disconnection push button, located in the side stick, to "bring" the aircraft into a "status" (Alternate Law 1) which would bring the aircraft back to manual, although maintaining a great deal of protections. This would be a pilot friendly status, once he could effectively handle and override aircraft built-in protections in case a serious situation arises. Once the problem was solved, he could return to Normal Law (provided certain conditions met) by switching the Auto Pilot ON.
