CRUISE
(Continued)
Carburetor ice, as evidenced by an unexplained drop in RPM, can be
removed by application of full carburetor heat. Upon regaining the
original RPM (with heat off), use the minimum amount of heat
(reference EIS CARB ºF display) to prevent ice from forming. Since the
heated air causes a richer mixture, readjust the mixture setting when
carburetor heat is to be used continuously in cruise flight.
The use of full carburetor heat is recommended during flight in heavy
rain to avoid the possibility of engine stoppage due to excessive water
ingestion or carburetor ice. The mixture setting should be readjusted for
smoothest operation. Power changes should be made cautiously,
followed by prompt adjustment of the mixture for smoothest operation.
LEANING WITHOUT EXHAUST GAS TEMPERATURE
(EGT) INDICATOR
BEST POWER CRUISE
Use the mixture control vernier adjustment to lean the fuel mixture by
slowly turning the mixture control knob in the counterclockwise
direction while monitoring engine RPM. As RPM increases, continue to
carefully lean the mixture until it reaches peak RPM. Slightly enrichen
mixture (turn mixture control knob clockwise) until a slight drop in
engine RPM is indicated. This is the Best Power Cruise setting.
CAUTION
EXCESSIVE LEANING WILL INCREASE ENGINE
TEMPERATURES AND MAY DAMAGE ENGINE. WHEN
INCREASING POWER, ENRICHEN MIXTURE, THEN
ADVANCE THE THROTTLE TO INCREASE RPM. WHEN
REDUCING POWER, RETARD THROTTLE, THEN
ADJUST THE MIXTURE CONTROL.
Lean the mixture for maximum RPM during all operations at any
altitude, including those below 3000 feet, when using 75% or less
power. Above 5000 feet, mixture may be leaned for maximum RPM
during full throttle climbs (after engine has accumulated 50 hours).
