Gergely,
If a system would tell you when you are getting "dangerously close to the limits" but wouldn't restrict you in anyway, that would be an extra layer of protection.
Just a word of caution there: as you probably know, such a system would only act as a protection if its specificity and detectivity were high enough. On the contrary, if the rates of false alarms and/or false negatives were to high, it might actually hinder the pilot rather than help him.
So the real problem may be feasibility: you speak of "basic airmanship 101", but some detection tasks which are quite obvious for humans are very tricky for computers. So "basic airmanship 101" may actually require "expert computership 999"...
