so could be starting a long way away from your desired speed. Setting normal pitch/power for, say, F5/180kts when you are in reality 40kts+ slower could make things worse, not better.
Wherein lies the value of knowing the numbers. The pilot with that knowledge, first, will identify the present situation, then where the aircraft should be, and set a suitable thrust/attitude combination to effect that change. My observation has been that your concern appears not to be a problem IF the pilot starts out with a reasonable knowledge of thrust/attitude combinations. This all presumes some learning and a reasonable amount of exposure practice to acquire a skill level.
SOPs are important and need to be applied, but there is an advantage in knowing a bit more than the assumed minimum competence level.
rather than seeing someone else set a performance attitude that is not quite what you expected
Which presumes the unhappy situation that both pilots have been asleep ?
