ICING

Back 12

- Pitot Heat -- ON
- Turn Back or chnge altitude
- Pull Cabin Heat control Full OUT
- Watch for signs of engine related icing conditions. An Unexplained Loss in engine speed could be caused by Ice blocking the Air Intake filter, or, in extremely rare instances,Ice completely blocking the fuel injection air reference tubes. Change the throttle Position to obtain maximum RPM. This may require either advancing or retarding the throttle dependent on where ice has accumulated in the system. Adjust mixture as required for max RPM.
- Plan a Landing at the nearest airport. With an extremely rapid ice build up select a suitable "off airport" landing site.
- With an Ice accumulation of 1/4 inch (5mm) or more on the wing leading edges, be prepared for sig higher stall speed and longer landing roll.
- Leave wing flaps retracted. with a severe ice build up on the Hz Tail, the change in wing wake airflow caused by flap extension could result in a loss of elevator effectiveness.
- Open left window and
