Ferret,
Don't know why but CADET always lodged in my head as simply Compass to True Add East. No really an acronym but hey, I can still remember it after all these years.
I have always had a soft spot for my down wind checks though:
M - my
F - friend
F - fergie
H - has a
H - heavenly
B - bosom
representing mixture, fuel, flaps, hatches, harnesses and brakes.
