Tyro - Good to hear that Airbus SOPs don't wait for the aircraft to tell you something is broken. Our company trainers give you a sideways glance if you even bring this info up (apart from during pre flight checks/engine start)!
Unlike ECAM Boeings secondary systems indicators (oil, Hyd, Vib etc) don't give a pop up for rate of change only when the system reaches a trigger level (normally the caution range)!!!
I personaly scan before entering the runway...at the 40 % N1 stable check and frequently during the climb (less so during cruise / descent).
