agusaleale;
I wouldnīt do it in that way. Iīd only record certain parameters of the flight just to introduce them in a program. It would gave me lots of useful information to evaluate the behaviour of the pilots. May be itīs already in use ....in this case forgive me for my appreciation.
That's what FOQA/FDA - Flight Data Analysis programs have been doing, in some cases (BA) for over fourty years, in other cases a few years.
A QAR - Quick Access Recorder records the same if not many more parameters than the crash recorder. It is analyzed by specialists, usually a small group of pilots designated for the task or an independant company, and the de-identified reports are provided to the airline's management.
Now, it is far, far more complex than this, so I might suggest you google, "FOQA" as a good place to start.
Data analysis is, as you suggest, proactive, and is looking for both trends and incidents/events. In many arrangements, calls to the crew are made not by management but by the pilots' own peers usually through an agreement with the airline. The program is extremely effective in discovering what the airplanes and crews are doing on a daily basis.
