Safety Information
Since flight in icing conditions is not an everyday occur-
renee, it is important that pilots maintain a proper proficiency
and awareness of the operating procedures necessary for
safe operation of the airplane and that the airplane is in a
condition for safe operation.
Ensure moisture drains in the airplane structure are main-
tained open as specified in the Aircraft Maintenance Manual,
so that moisture
will not collect and cause freezing in the
control cable area. Also, control surface tab hinges should
be maintained and lubricated as specified in the Aircraft
Maintenance Manual.
In icing conditions the autopilot should be disengaged at an
altitude sufficient to permit the pilot to gain the feel of the
airplane prior to landing. In no case should this be less than
the minimum altitude specified in the Autopilot Airplane
Flight Manual Supplement.
Observe the procedures set forth in your Pilot's Operating
Handbook and FAA Approved Airplane Flight Manual during
operation in icing conditions.
Activate your deice and anti-icing systems before entering
an area of moisture where you are likely to go through a
freezing level, to make sure all necessary equipment is
operative.
Rapid cycling of deice boots or cycling before at least one-
half inch
(1/2") of ice has accumulated (measured in the
chordwise direction or forward from the leading edge), may
cause the ice to grow outside the contour of the inflated
boots and prevent ice removal.
For any owner or pilot whose use pattern for an airplane
exposes it to icing encounters, the following references are
required reading for safe flying:
