Engine Start engine_start

Parking brakeSET
Master switch (battery)ON
Beacon / rotating anti-collision lightON
Primer — use as required for conditions; lock after useAS REQUIRED, LOCKED
Cold starts generally require more priming strokes than warm restarts. Consult the POH starting procedure for guidance by temperature. Always ensure the primer is fully in and locked before starting to avoid fuel injection into the engine at an uncontrolled rate.
ThrottleSLIGHTLY OPEN (APPROXIMATELY HALF INCH)
Visually verify the propeller arc is clear, then call 'CLEAR PROP'
Ignition switchSTART, THEN RELEASE TO BOTH
Oil pressureRISES WITHIN 30 SECONDS — IF NOT, SHUT DOWN

Run-Up / Before Takeoff before_takeoff

Parking brakeSET
Engine oil temperature and pressureIN GREEN ARCS
MixtureRICH (ADJUST FOR DENSITY ALTITUDE PER POH)
Carburetor heatCOLD (OFF)
Throttle — advance to run-up power per POHRUN-UP RPM SET
Magnetos — test LEFT, then RIGHT, then BOTH; note RPM drop on each magnetoDROPS WITHIN POH LIMITS, RETURNS ON BOTH
Maximum allowable RPM drop on a single magneto and the maximum spread between the two magnetos are specified in the aircraft POH and are not stated here. A rough or excessive drop requires investigation before flight.
Carburetor heat — apply and monitor for RPM change, then return to COLDSLIGHT RPM DROP (ICE CHECK), THEN COLD
A smooth RPM drop and subsequent rise when returning to COLD indicates the carb heat is functioning. An initial RPM drop followed by a rough idle suggests carburetor ice was present and is clearing.
Throttle — reduce to idle and verify idle is smoothIDLE SMOOTH AND STABLE
Suction gauge (vacuum)IN GREEN ARC
Flight controls — final check for free and correct deflectionFREE AND CORRECT
Flaps — set for departure (select if short-field; normally up)SET AS REQUIRED
Elevator trimTAKEOFF POSITION

Maintain directional control with rudder — use right rudder for propeller torque
Lift-off — rotate at airspeed per POHAIRSPEED PER POH

Climb climb

Airspeed — establish normal climb speed per POHCLIMB SPEED PER POH
Carburetor heatCOLD UNLESS ICING CONDITIONS SUSPECTED
ThrottleFULL POWER (OR AS PER POH FOR CRUISE CLIMB)
MixtureRICH OR LEANED PER POH FOR HIGH-ALTITUDE FIELDS
Engine instruments — oil temperature, oil pressureIN GREEN ARCS
TrimADJUST FOR HANDS-OFF CLIMB
Scan for traffic and maintain clearing turns as appropriate

Cruise cruise

Throttle — set cruise power per POH performance tablesCRUISE POWER SET
Carburetor heat — check for suspected icing conditions; otherwise coldCOLD, OR ON AS REQUIRED
Mixture — lean per POH for altitude and power settingLEANED PER POH
Engine instruments — oil temperature, oil pressure, ammeterIN RANGE
Fuel quantity — note quantity and check against flight plan burnADEQUATE FOR PLANNED FLIGHT PLUS RESERVE
TrimADJUSTED FOR LEVEL FLIGHT
Altimeter and directional gyroCHECK AND RESET AS NEEDED
Maintain cruise altitude, track, and traffic scan

Descent descent

Carburetor heat — apply before reducing power to prevent carburetor icingON BEFORE POWER REDUCTION
Fixed-pitch carbureted engines are particularly susceptible to carburetor ice during power reductions. Apply carb heat before throttling back in the descent.
