MODEL 208B 867 SHP AIRPLANE HANDLING, SERVICE
GARMIN G1000 AND MAINTENANCE
U.S.
GROUND DEICE/ANTI-ICE OPERATIONS
During cold weather operations, flight crews are responsible for making
sure that the airplane is free of ice contamination. Type I deice, and
Type II, Type III, or Type IV anti-ice fluids may be used to ensure
compliance with FAA regulations, which require that all critical
components (wings, control surfaces and engine inlets as an example)
be free of snow, ice, or frost before takeoff. The deicing process is
intended to restore the airplane to a clean configuration so that neither
aerodynamic characteristics nor mechanical interference from
contaminants will occur.
Type II, Type III, and Type IV anti-ice fluid is
designed for use on airplanes with a VR speed of 85
knots or greater. Whenever Type II, Type III, or Type
IV anti-ice fluid is applied to the airplane, the takeoff
flap setting is limited to UP and the VR is 88 KCAS
(83 KIAS). Refer to Section 2, Limitations, Type II,
Type III, and Type IV Anti-Ice Fluid Takeoff
Limitations and Section 5, Performance, Figure 5-11
and Figure 5-27, for Flaps Up Takeoff Distances and
liftoff speeds in KIAS. Figures 5-11 and 5-27, Flaps
Up Takeoff Distance charts start with the airplane’s
maximum weight for normal operations.
It is recommended that flight crews refamiliarize
themselves seasonally with the following publications for
expanded deice and anti-ice procedures:
• Cessna 208 Series Maintenance Manual, Chapter 12.
• FAA Advisory Circular AC135-17, dated 14 December
1994 or later.
• FAA Advisory Circular AC20-117, dated 17 December
1982 or later.
• Cessna Aircraft Company SNL 08-1 and FAA Notice
8900.196: Revised FAA-Approved Deicing Program
Updates, Winter 2012-2013.
