GENERAL
Pneumatic de-icing boots, installed on the leading edges of the wings
and horizontal stabilizer, provide a measure of protection if unexpected
icing conditions are encountered. Controls for the de-icing system consist
of a spring-loaded on-off rocker switch on the left switch and control panel,
a pressure indicator light on the upper left side of the instrument panel,
and a 5-amp circuit breaker switch on the left sidewall circuit breaker
panel. The two-position de-icing switch, labeled DE-ICE PRESS, is spring-
loaded to the normal off (lower) position. When pushed to the ON (upper)
position and released, it will activate one de-icing cycle. Each time a cycle
is desired, the switch must be pushed to the ON position and released. The
pressure indicator light, labeled DE-ICE PRESSURE, should come on
within four seconds after the cycle is initiated and remain on for two to
three seconds if the system is operating properly.
De-icing boots have a special electrically-conductive coating to bleed
off static electricity which causes radio interference and could perforate
the boots. Fueling and other servicing should be done carefully to avoid
damage to the conductive coating or tearing of the boot. Keep the boots
clean and free from oil and grease which can swell the rubber. Wash them
with mild soap and water, using benzol or unleaded gasoline to remove
stubborn grease. Do not scrub the boots, and be sure towipe off all solvent
before it dries. Small tears and abrasions can be repaired temporarily and
the conductive coating can be renewed, without removing the boots. Your
Cessna Dealer has the proper materials and know-how to do this correctly.
An ice detector light is also installed to facilitate the detection of wing
ice at night or during reduced visibility. The ice detector light system
consists of a light installed on the left side of the cowl deck forward of the
windshield which is positioned to illuminate the leading edge of the wing,
and a rocker-type switch located on the left switch and control panel.
