i used to have a detailed list with me, but memorizing things
was difficult. so, as soon as i knew where all the switches
were and what they were meant for, i wouldn't need those
details anymore. then, i could just go with pvi, uv-26, apu
start-up, engines shutdown, etc.
engines start-up, for instance, involves checking or
activating 15+ switches for each engine, besides monitoring
gauges and knowing the waiting times.
so, before anything else, know what you are doing. as the
manual says, study 'till you feel at home in the cockpit.
