"Managing and handling" advanced Systems (Human machine interfacing issue)
RR_NDB:
The crew never should be "presented" (specially at critical moments) with System "outputs" that they are not capable to understand very fast
What is not clear when output is ECAM message:
F/CTL ALTN LAW (PROT LOST)
MAX SPEED……330/.82*
How would you suggest presenting this more clearly to crew?
* actual values depend on configuration.
If you are referring to the intermittent STALLSTALL, I fully agree this should have never been silenced when AOA was above the threshold value whether speed was valid or not.
The crews, "Redundant Systems, operators" always must "have chances" to "keep flying" their increasingly complex, and not perfect (never will be), machines.
Once again, the system doesn’t make up the inputs itself, it executes them from input of PF (AP) and in ALT LAW in such a manner it would not hinder PF to recover A/C from the upset.
