PJ - the problem with your suggestion is that it does not cover all bases, in that with a total baro data failure one could see a crew 'floundering' for a pitch attitude, whereas 5 is SAFE, will not cause a stall from steady cruise and will then give time to enter the trouble shooting phase with pitch/power from the QRH. I really see no need to change OR to worry about the definition/interpretation of 'danger' either. It will work, it will give 'breathing space and it is easy to remember without having to try and find a pitch attitude that produces a steady GPS altitude! Heaven knows the ship is complicated enough without adding to it.
Ian W - indeed - and the exercise is self satisfying in a circular way, since it can be demonstrated that with improved sim time and training sim performance is improved, and it is there that thankfully 99% of our aviation 'nasties' happen. When they happen in the real world we discover the holes.
