First ac Chipmunk circa 1969 Liverpool UAS:
Pre-start: Fuel on, Brakes on, Throttle Closed, Switches off...
The ground crew response always turned me on...
BREACH inserted, COWLING secure, CLEAR to start.
Post Start: BANG!! Set 1100 rpm, Oil pressure rising, Genny Warning light out, Radio on, Ignition Switches dead cut, Artificial Horizon erect, DI set and uncaged, Pitot heater, Radio call, Altimeter set, Chocks. (SOGRIADPRAC)
Pre-Takeoff: Trim 2 divisions nose down, Throttle friction nut finger tight, Mixture rich/Carbair wired hot, Fuel On and gated full starboard full port, Flaps as required up, Gyros set and uncaged, Gauges within limits, Pitot heater, Hood, Harness. (TTMFFGGPHH).
Last ac? Sea King Mk 5 circa 2002 - Can't remember any of the CX!!
Oh yes, STUPRECCC: Did that in anger on my second (and final) solo with a stick trim failure during the dive. Subsequently departed the runway through the goose necks before taxying back and handing in resignation (or was I chopped) - Stu Price the beefer. Lovely ac just couldn't land it, specially with no hyds.
