Downwind checks Mnemonic
In Harvards in the early 1950's and possibly today, the downwind check was remembered as a mnemonic:
“TMPFFSGGHHH”
and recited as “Tickle my ***** for ****’s sake goody goody ha ha ha”, all of which was intended to prompt for Throttle–Mixture–Pitch, etc.
What were the etcetera bits i.e. "FFSGGHHH"?
