5F6B - you are giving the correct Directing Staff solution. Aircraft are vastly more complex than they were, but reliability of engines and components have improved beyond recognition. No simulators in my day either (the first 'simulators' that I saw would now be called primitive procedure trainers). I still think the best solution is to have experienced people from Handling Sqn or the type OTU be responsible both for the writing of and currency of the book of words. The manufacturers manual could be a good place to start from. The publication must be written by pilots for pilots. It must not be riddled with legal jargon or become a bureaucrats plaything.
