Does anyone have a crib sheet for the various "gaits" of the 172RG. By
gaits I mean the various MP/RPM/configuration settings (and their
associated airspeeds) that you use in different regimes of flight;
cruise, cruise climb/descent, holding, approach outside the OM, inside
the OM, etc.

o Climb: Cowl flaps open. Full throttle throughout climb, reduce RPM to 2500
at 1,000' AGL.

o Cruise: 25" MAP or full throttle, 2500 RPM, mixture lean of peak if
possible. Keep cowl flaps open in any but very cold weather; top of Cessna
CHT green is way too hot.

o Cruise descent: 18" or 20" MAP (depending on how smooth the air is), pitch
for 500 FPM. Cowl flaps closed.

o Holding: 18" MAP, gear & flaps up.

o Initial instr. approach segments: 20" MAP, 2500 RPM.

o Final instr. approach segment (slow): Mixture rich, 17" MAP (no wind), prop
in fine pitch, gear down, 1/3 flaps.

o Final instr. approach segment (fast) Mixture rich, 19" MAP (no wind),
prop in fine pitch, no gear or flaps until 1/4 mile final, then extend gear
(don't forget!) and 1/3 flaps simultaneously, then rest of flaps below IAS
white arc.

o Landing:
-Mixture rich, 17" MAP, prop in fine pitch, 1/3 flaps & gear down at
midfield downwind.
-15" MAP abeam touchdown.
-2/3 flaps, 80 KIAS on base leg.
-Full flaps, 70 KIAS on final.
-Throttle idle, 65 KIAS over the numbers.
