Move propeller control to maximum RPM to minimize ice build- up on propeller blades. If ice
builds up or sheds unevenly on propeller, vibration will occur. If excessive vibration is noted, mo-
mentarily reduce engine speed with propeller control to bottom of GREEN ARC (Lowest RPM),
then rapidly move control FULL FORWARD.
-NOTE-
Cycling RPM flexes propeller blades and high RPM increases centrifugal force
which improves propeller capability to shed ice.
As ice builds on the airframe, move elevator control fore and aft slightly to break any ice buildup
that may have bridged gap between elevator horn and horizontal stabilizer.
Watch for signs of induction air filter blockage due to ice build- up; increase throttle setting to
maintain engine power.
-NOTE-
If ice blocks induction air filter, alternate air system will open automatically.
With ice accumulation of ¼ inch or more on the airframe, be prepared for a significant increase in
aircraft weight and drag. This will result in significantly reduced cruise and climb performance
and higher stall speeds. Plan for higher approach speeds requiring higher power settings and
longer landing rolls.
Stall warning system may be inoperative.
-CAUTION-
-NOTE-
The defroster may not clear ice from windshield. If necessary open pilot’s storm
window for visibility in landing approach and touchdown.
With ice accumulations of 1 inch or less, use no more than 10  wing flaps for approach and land-
ing. For ice accumulation of 1 inch or more, fly approaches and landing with flaps retracted to
maintain better pitch control. Fly approach speed at least 15 knots faster than normal, expect a
higher stall speed, resulting in higher touchdown speed with longer landing roll. Use normal flare
and touchdown technique.
Missed approaches SHOULD BE AVOIDED whenever possible because of severely reduced
climb performance. If a go-around is mandatory, apply full power, retract landing gear when ob-
stacles are cleared; maintain 90 KIAS and retract wing flaps.
AVOID FURTHER ICING CONDITIONS
