ICING
▲ WARNING:
It is prohibited to fly in known icing conditions.
Icing has a very strong negative effect on the
aerodynamic characteristics of the aircraft. Stalling
speed increases.
Proceed as follows when inadvertently encountering icing:
1) Pitot heat switch ....................................................... ON (if installed)
If no pitot heat installed, expect airspeed indications to become
unreliable
2) Immediately leave the region in which the icing occurred. If possible
change the altitude to obtain an outside air temperature that is less
conductive to icing
3) Cabin heat / defrost ........................................................ As required
4) Alternate induction air ............................................................ OPEN
5) Increase power; make quick power changes from time to time to try
to clear ice from the propeller blades.
Plan to land at the nearest airfield. If the build-up of ice is extremely fast,
execute an off-airfield forced landing.
Note
:
A layer of 0.5 cm (0.2 in) on the leading
edge of the wing substantially increases the stalling
speed. If needed, use a higher than normal approach
speed: 145 km/h (78 KIAS). Do not use flaps.
