But although the pitch values are easily remembered (remember the mnemonic "(DTD)585" for the B707?), the N1 or EPR settings are less so, unless you have noted the setting just before the IAS indications go AWOL. It can take a while to find the appropriate page in the QRH. On some a/c, the total fuel flow is a better tool than N1 or EPR, but it's not generally taught, and digital flowmeters don't seem to be as user-friendly as the old analogue ones.

This is all very elementary knowledge. It should be taught as part of the basic type rating; otherwise you should not be certified on your licence to fly the aircraft. Unfortunately the accent in type ratings is on flying the automatics when there should an equal emphasis placed on manual handling on instruments. There is a difference between becoming a flight deck "Manager" as most pilots are and being a professional fully qualified airman in every sense of the word "Airman".
