INADVERTENT ICING ENCOUNTER
1.
Turn pitot heat switch ON (if installed).
2.
Turn back or change altitude to obtain an outside air temperature
that is less conducive to icing.
3.
Pull cabin heat and cabin air controls full out and open defroster
valves to obtain maximum defroster airflow.
4.
Increase engine speed to minimize ice build-up on propeller
blades.
5.
Watch for signs of carburetor air filter ice and apply carburetor
heat as required. An unexplained loss in manifold pressure could
be caused by carburetor ice or air intake filter ice. Lean the mixture
if carburetor heat is used continuously.
