GROUND DEICEIANTI-ICE OPERATIONS

TYPE
Ill ANTI-ICE FLUID
NOTE
Freezing point of Type Ill fluid mixture must be at least
10°C (18°F) below OAT.
Holdover time starts when last application has begun.
Application techniques for Type Ill fluid are the same as
for Type I and Type
II, except that since the airplane is
already clean, the application should last only long
enough to properly coat the airplane surfaces.
Type Ill fluid should be applied undiluted at ambient
temperature to a "clean" airplane within three minutes
after deicing is completed, due to the limited holdover
times for Type I deice fluid. Type
Ill fluid is, however,
sometimes heated and sprayed as a deicin fluid
Because of this, it should be considered a Type I
fuid, as
the heat may change the characteristics of the
thickening agents in the fluid. Type
Ill fluid therefore,
applied in this manner, will not be as effective as it would
be if it were applied at ambient temperature.
TYPE
IV ANTI-ICE FLUID
CAUTION
THE TlME OF PROTECTION WILL BE SHORTENED IN
HEAVY WEATHER CONDITIONS. HEAVY
PRECIPITATION RATES,
HlGH MOISTURE CONTENT,
HlGH WIND VELOCITY, OR JET BLAST MAY REDUCE
HOLDOVER TlME BELOW THE LOWEST TlME STATED
IN THE RANGE. HOLDOVER TlME MAY BE REDUCED
WHEN AIRCRAFT
SKIN TEMPERATURE IS LOWER
THAN OAT.
