LANDING GEAR RETRACTION
Landing gear should normally be retracted after reaching the point down the runway beyond which
a wheels down landing on the remaining runway could no longer be made. Before initiating the
retraction cycle, tap the brakes to stop all main wheel rotation. After retraction is complete verify
that the gear locked lights are out and the gear warn light is out.
ENROUTE CLIMB
Normal climbs can be conducted at 100 to 120 KIAS with the power set to 24 inches Hg or full
I throttle if less, 2500 rpm, and mixture set to 18 gallons per hour or full rich. These settings
correspond to approximately 75% power and are represented for quick reference by the upper
extent of the major green arc markings on the manifold pressure gauge, tachometer, and fuel flow
gauge. This combination provides a reasonable combination of rate of climb, visibility over the
nose, cabin noise level, and speed over the ground.
If higher climb performance is necessary or desired, the best rate of climb speed should be used
along with maximum available power. Best rate of climb speed is a constant 100 KIAS at sea level
through 8000 feet. At 8000 feet, the speed may be reduced to 90 KIAS decreasing above 8000 feet
at the rate of 1 knot per 2000 fect. Maximum power for climb is with full throttle, 2700 rpm, and
mixture set full rich. Above 8000 feet, if necessary, the mixture may be leaned for smooth
operation.
If a nearby obstruction requires a steeper climb angle, the best angle of climb speed should be
used along with maximum available power. Best angle of climb speed is 75 KlAS at sea level
increasing linearly to 82 KIAS at 10000 feet. This type of climb should only be of short duration to
avoid overheating the engine.
CRUISE
Normal cruising is conducted at 75% power and below. At higher powers the mixture may not be
leaned, thereby producing inefficient mileage. At power settings of 75% and below the mixture
should be leaned. The cruise, range, and endurance performance provided in Section 5 is based
upon the use of a best economy mixture strength. This mixture is achieved with the use of the EGT
gauge by leaning slowly to peak EGT as discussed below.
A best power mixture strength may also be used if desired by leaning with reference to the EGT
gauge to 100°F rich of peak EGT. This will result in speeds that are 3 - 4 KT AS faster than shown
for the same flight and power conditions in Section 5 and fuel consumption figures approximately 2
- 3 GPH higher at a given horsepower.
At higher altitudes, engine speeds above 2500 rpm may be used for cruising flight as shown by the
narrow green arc on the tachometer. This allows use of75% power to a higher altitude with a
modest increase in cabin noise due to the higher rpm. Specific power settings can be determined
by referenLe to the Section 5 Cruise charts.
