Other emergencies
7.7.1
Vibration
If vibrations appear:
1. Set engine speed to power setting where the vibrations are the
lowest.
2. Land at the nearest airfield or perform a precautionary landing
according to 3.6.2
7.7.2
Carburetor icing
Carburetor icing mostly occurs when getting into an area of humid-
ity formation. The carburettor icing shows itself through a decrease in en-
gine power and an increase of engine temperatures.
To recover the engine power, the following procedure is recom-
mended:
1. Apply carby heater system
2. Throttle
- set for 1/3 power
3. If possible, leave the icing area, and use carby heat during flight
4. Gradually increase the engine power to cruise conditions
after 1-2 minutes.
If you fail to recover the engine power, land at the nearest airfield
(if possible) or depending on circumstance, execute a precaution-
ary landing according to 3.6.2
