lowest

landing according to par. 3.8.2. Safety landing.
3.10.2 Carburetor icing
Carburetor icing happens when air temperature drop in the
carburetor occurs due to its acceleration in the carburetor and
further cooling by evaporating fuel. Carburetor icing mostly happens
during descending and approaching for landing (low engine RPM).
Carburetor icing shows itself by engine power decreasing and by
engine temperature increasing.
Recommended procedure for engine power regeneration is as
follows:
1. CARB. PREHEATER (if installed)
ON

set idle and cruising
power again
NOTE
Ice coating in the carburetor should be removed
by decrease and reincrease of engine power.
3. If the engine power is not successfully increased, then carry
out landing at the nearest suitable airport or, if it is not
possible, carry out precautionary landing according to par.
3.8.2 Precautionary landing.
