CAUTION
Prolonged operation at powers above 75% with
a leaned mixture can result in engine damage.
While establishing Best Economy Cruise
Mixture, below 6,000 feet, care must be taken
not to remain in the range above 75% power
more than 15 seconds while leaning. Above
6,000 feet the engine is incapable of generating
more than 75%.
Always remember that the electric fuel pump should be turned ON
before switching tanks, and should be left on for a short period thereafter. In
order to keep the airplane in best lateral trim during cruising flight, the fuel
should be used alternately from each tank. It is recommended that one tank
be used for one hour after takeoff, then the other tank be used for two hours;
then return to the first tank, which will have approximately one and one half
hours of fuel remaining if the tanks were full at takeoff. The second tank will
contain approximately one half hour of fuel. Do not run tanks completely
dry in flight. The electric fuel pump should be normally OFF, so that any
malfunction of the engine driven fuel pump is immediately apparent. If signs
of fuel starvation should occur at any time during flight, fuel exhaustion
should be suspected, at which time the fuel selector should be immediately
positioned to the other tank and the electric fuel pump switched to the ON
position.
4.29 DESCENT
NORMAL
To achieve the performance on Figure 5-31, a power on descent must
be used. The throttle should be set for 2500 RPM, mixture full rich and
maintain an airspeed of 126 KIAS. In case carburetor ice is encountered
apply full carburetor heat.
POWER OFF
If a prolonged power off descent is to be made, apply full carburetor
heat prior to power reduction if icing conditions are suspected,. Throttle
should be retarded and mixture control leaned as required. Power response
should be verified approximately every 30 seconds by partially opening and
then closing the throttle (clearing the engine). When leveling off, enrichen
mixture, set power as required and select carburetor heat off unless
carburetor icing conditions are suspected.
