GROUND DEICEIANTI-ICE OPERATIONS (Continued)
CAUTION
NOTE
Deicing and anti-icing procedures must be closely
coordinated between the pilot in command and ground
crews, and carried out in a timely manner. Ultimate
responsibility for safety of flight rests with the pilot in
command, and any decisions to deice or anti-ice an
airplane must be accomplished under his or her direct
supervision.
The first area to be deiced and anti-iced should be
visible from the cockpit and should be used to provide a
conservative estimate for subsequent ice accumulations
on unseen areas of the airplane before initiating takeoff.
Due to the weight and C.G changes which occur while
deicing the airplane, a tail stand should be placed under
the tail to prevent the airplane from tipping on its tail.
1 HOLDOVER TIMETABLE (TYPE I, TYPE 11, TYPE Ill AND
TYPE
IV FLUIDS)
NOTE
Refer to
FAA Flight Standards Information Bulletin for Air
1
Transportation FSAT 05-02, dated 10-18-05 or later, for
holdover timetables.
The length of time that de-icing and anti-icing fluids remain effective is
known as "holdover time". The holdover timetables for Type
I de-icing,
1 and Type II, Type Ill, or Type IV anti-icing fluids are only an estimation
and vary depending on many factors, such as temperature,
precipitation type, wind and aircraft skin temperature. The holdover
1 timetables for SAE and IS0 Type I deicing, and Type II, Type Ill, and
Type
IV anti-icing fluid mixtures are only an estimation and vary
depending on many factors, such as, temperature (OAT), precipitation
type, wind and aircraft skin temperature.
