Cruise
During icing encounters in cruise, increase engine power to maintain
cruise speed as ice accumulates on the unprotected areas and causes
the aircraft to slow down.
The autopilot may be used in icing conditions. However, every 30
minutes the autopilot should be disconnected to detect any out-of-trim
conditions caused by ice buildup. If significant out-of-trim or other
anomalous conditions are detected, the autopilot should remain off for
the remainder of the icing encounter.
When disconnecting the autopilot with ice accretions on the airplane,
the pilot should be alert for out-of-trim forces.
