Rhyme as Reason
I'm trying to gather some of those snappy little catchphrases that instructors use to get the point across. People remember these little rhymes and respond to them more positively than they do to long-winded explanations:
"Doing a small amount of repair work early on may be help to avoid substantial remedial effort at a later date"
is boring and forgettable, but
"A stitch in time saves nine"
is far more likely to be believed and retained.
So for rudder input after an engine failure we might say "Squeeze and freeze"
or for setting QNH: "From high to low, beware below"
It would be good for all of us to share these morsels of instructional goodness, so what have you got?
