As a flight engineer, I have always flown older generation aircraft. Whilst I am conversant with modern avionics/FMS, I sometimes wonder if they generate a lower arousal state on the flight deck? I would never denigrate the SA they can give, nor deny the flexibility and time savings they present, but when I read some of the tech threads with people contradicting which law the system is operating in, it does make me ponder over the validity of some of the training packages that people are given. Do any of you 'more mature' operators miss the higher workload of yesteryear ????
