Several posters have danced around the issue but it's better to be direct. The "Airbus philosophy" of envelope protection needs to be revisited. Either one of two things is going to happen over the long haul.
Scenario One: Flight envelope protection is lost and the pilot guesses. Solution: If all the pilot is going to do is guess the computer can do that just as well and probably better.
AUTOPILOT OFF
AUTO THRUST OFF
FLIGHT DIRECTORS OFF
IF AIRSPEED IS UNKNOWN, SET 90% N1
That isn't difficult logic for software engineers to program...
Scenario Two. Flight envelope protection is lost and the pilot uses his superior flying skills to correct the problem.
This for many is the preferred solution. However, it seems that maybe it isn't working as well as one would hope.
