bfisk An airline that prides themselves in high operational and safety standards, requires all their pilots to memorise ALL checklists
There is no pride in such training culture. In fact it's unsafe and very dangerous. Because crews would have a propensity to do the entire drill by memory.
It depends on the context. There is no shortage of pilots that wouldn't have a clue where to find certain checklists from the QRH without licking their fingers and thumbing laboriously through the contents of a QRH trying to find how to carry out smoke evacuation drills. The fact that the smoke could be so bad that they would not be able to read a checklist never occurs to them.
I once observed a pilot in a simulator still heads down turning the pages of the QRH trying to find the engine failure/shut down (non-memory) drill when the aircraft was in a 90 degree angle of bank and about to hit the deck at 340 knots.
Every pilot worth his salt should have a sound working knowledge of every checklist in the QRH and be able to find any page within a few seconds. Too many slack pilots figure why bother to study QRH contents as there will always be stacks of time to find the required drills when the moment arrives. Most of the time they are probably right - but one night they might have left it too late.
