Takeoff
Takeoff power set to 32 in MP, 2400 RPM and Mixture at 24 gph. Manifold Pressure MP and Fuel Flow
FF needles (same gauge – under the turn coordinator) should both be pointing to near the red line. RPM
(under the VSI) should be near red line.
Climbs
Climb power should be set at 400 feet and set to 25 in MP, 2400 RPM and Mixture to 16 GPH, airspeed
95-100 KIAS. Throughout the climb, Manifold Pressure will have to be increased (1” per 1000’) to
maintain 25 in MP. 200 feet prior to level off, close the cowl flaps to reduce rapid cooling of the engine
as it accelerates.
Cruise
Cruise power setting should be set to 24 in MP and 2300 RPM; 2250 RPM is also acceptable.
Cruise Mixture Leaning
Lean the mixture slowly until the T.I.T. peaks and begins to drop or until reaching the T.I.T. redline.
Enrich the mixture 50 F rich of peak T.I.T. or 50 F rich of red line (whichever is lower) for recommended
lean mixture.
NOTE: Leaning with a T.I.T. indicator is permitted only when using power settings within the green arc
ranges.
NOTE: Any change in altitude or power setting WILL REQUIRE a change in the recommended lean
mixture setting and a recheck of the T.I.T. setting.
NOTE: Operation on the lean side of peak T.I.T. is NOT APPROVED.
Stage Cooling & Descent
Pre -descent planning: Five minutes prior to starting descent, reduce power 1” per minute until you
reach 20 in MP. After initiating descent, continue to reduce MP by 1” per 1000’ to maintain 20” MP.
Cowl flaps should be closed for descent.
Descent should be initiated far enough in advance of estimated landing to allow a gradual rate of
descent (i.e., 500 FPM for passenger comfort) at cruising speed. Use this simple calculation – Cruising at
10,000’ with Circuit at 5,000’ will need to lose 5000’. At 500 fpm will need to start descent at least 10
min (2 min per 1000’) prior to arriving in the circuit. Travelling at close to 2 ½ miles per minute in the
descent, you will be starting your descent at least 25 miles prior to the airport. However, you will need
