True Virgins Make Dull Company....I can remember the memory aid, but forget what it stood for...
Same with me. I had trouble with the RAF's "My Friend Fred ..." during my Chipmunk days, so I just learnt "Mixture, Fuel, Flaps, Hatches, Harness, Brakes off."
It still stands me in good stead after many years, with just a prefix of "Gear down" or "Undercarriage down", depending where I'm flying!
