TYPE III ANTI-ICE FLUID
NOTE
•
Freezing point of Type III fluid mixture must be at least
7°C (13°F) below OAT.
•
Holdover time starts when last application has begun.
•
Application techniques for Type III fluid are the same as
for Type I, except that since the airplane is already
clean, the application should last only long enough to
properly coat the airplane surfaces.
•
Type III fluid must be applied undiluted at ambient
temperature to a “clean” airplane within 3 minutes after
deicing is completed due to the limited holdover times of
Type I deice fluid. However, Type III fluid is sometimes
heated and sprayed as a deicing fluid. For this case, it
should be considered a Type I fluid, as the heat may
change the characteristics of the thickening agents in the
fluid. Therefore, Type II fluid applied in this manner will
not be as effective as it would be if it were applied at
ambient temperature.
WARNING
When ground icing conditions are present, a pre-
takeoff contamination check must be conducted by
the pilot in command within 5 minutes of takeoff,
preferably just prior to taxiing onto the active
runway. Critical areas of the airplane such as
empennage, wings, windshield, control surfaces,
and engine inlets must be checked to make sure
they are free of ice, slush, and snow and that the
anti-ice fluid is still protecting the airplane.
