SECTION 4
NORMAL PROCEDURES
4.25 CLIMB (4.5i)
4.25a Maximum Continuous Power Climb (4.5i)
The best rate of climb at gross weight and maximum continuous power
will be obtained at 110 KIAS. The best angle of climb may be obtained at 81
KIAS. The recommended procedure for climb is to use maximum continuous
power with the mixture full RICH. Under some off standard conditions, the
manifold pressure indication will exceed its indicated limits at full throttle.
Adjust power to remain within limits. Set the cabin pressurization controls in
accordance with paragraph 4.45. The emergency (EMERG) fuel pump should
be OFF when reaching a safe altitude.
4.25b Cruise Climb (4.5i)
For reduced enroute fuel consumption in climb at a higher enroute climb
speed of 125 KIAS, reduce the manifold pressure to 35 in. Hg, use 2500 rpm,
and lean the mixture to produce a fuel flow of 32 gph. Set the cabin
pressurization controls in accordance with paragraph 4.45. The emergency
(EMERG) fuel pump should be OFF when reaching a safe altitude.
4.27 CRUISE (4.5j)
Operation above 25,000 feet is not approved.
To maintain lateral balance, alternate between right
and left fuel tanks. See paragraphs 2.23 and 7.17.
For proper mid range accuracy, fuel quantity readings
should be taken when the aircraft is in coordinated
level flight at zero degrees bank angle. (Pitch, roll and
yaw.) Failure to observe fuel quantity in this manner
will result in erroneous readings due to wing cross
section, low dihedral angle and fuel tank geometry.
If readings are taken in configurations other than
coordinated level flight at zero degrees bank angle,
there may be periods during flight when the accuracy
of the fuel quantity gauging system will appear to be
incorrect by seeming to present an unchanging
quantity in spite of fuel being consumed from the tank.
