SECTION 4
NORMAL PROCEDURES
(AMPLIFIED PROCEDURES)
(~o~~402C
On long runways, the landing gear should be retracted at the point over
the
runway where a wheels-down forced landing on that runway would become
impractical. However, on short runways it may be preferable to retract the
landing gear
after the airplane is safely airborne.
Power reduction will vary according to the requirements of the traffic
pattern or surrounding terrain, weight, field elevation, temperature,
environmental considerations
and engine condition. However, a normal after
takeoff power setting is 2450 RPM and 29.5 inches Hg. manifold pressure.
CLIMB
CRUISE CLIMB
I. Power - 2450 RPM and 29.5 inches H9.
2. Airspeed - 115 to 140 KIAS.
3. Mixtures - ADJUST to climb fuel flow.
4.
Cowl Flaps - AS REQUIRED.
5. Propellers - SYNCHRONIZE manually.
6. Quadrant Friction Lock - TIGHTEN securely (With Synchrophaser
Installed).
7. Propeller Synchrophaser - PHASE (Optional System). Li9ht should
illuminate continuously.
a. Phasing
Knob - ADJUST for desired phasing position.
MAXIMUM CLIMB
I. Power - 2600 RPM and 39.0 inches H9. below 16,000 feet.
Placarded manifold pressure above 16,000 feet.
2. Airspeed - 109 KIAS.
3. Mixtures - SET to white trian9le on fuel flow 9age below 16,000
feet.
LEAN as required above 16,000 feet.
4. Cowl Flaps - AS REQUIRED.
Power settings for climb should be limited to 2600 RPM and 39.0 inches
Hg.manifold pressure
below 16,000 feet and placarded manifold pressures
above 16,000 feet.

Normal cruising climb is recommended where practical and should be ~~,
conducted at 115 to 140 KIAS, using approximately 75% of maximum normal
operating power (2450 RPM and 29.5 inches Hg. or 2300 RPM and 30.3 inches
Hg. manifold pressure). The mixture should be leaned in this type of climb
to give the desired fuel
flow in the climb dial range (blue segment) which
is approximately best power mixture.
If it is necessary to climb rapidly to clear mountains or reach favor-
able
winds at high altitudes, the all engines best rate-of-climb speed of r~"~
109 KIAS should be used with maximum normal operating power. During
maximum performance climbs, the mixture should be set to maintain fuel
flows at the white triangle up to the engine critical altitude and at the
appropriate climb
power range above critical altitude. It is recommended
that the auxiliary fuel pumps be ON, and the mixture remain at the climb
mixture
setting for approximately 5 minutes after establishing cruising
flight before leaning is initiated. This procedure will eliminate fuel
vaporization
problems likely to occur from rapid altitude changes.
