TYPE IV FLUIDS)
(Continued)
TYPE IV ANTI-ICE FLUID
CAUTION
The time of protection will be shortened in heavy
weather conditions. Heavy precipitation rates, high
moisture content, high wind velocity, or jet blast may
reduce holdover time below the lowest time stated in
the range. Holdover time may be reduced when
airplane skin temperature is lower than OAT.
NOTE
•
Freezing point of Type IV fluid mixture must be at least
7°C (13°F) below OAT.
•
Holdover time starts when last application has begun.
•
Application techniques for Type IV 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 IV fluid can be applied undiluted at ambient
temperature to a “clean” airplane within three minutes
after deicing is completed, due to the limited holdover
times of Type I deice fluid. Type IV fluid is however,
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. Type IV fluid therefore, applied in this
manner, will not be as effective as it would be if it were
applied at ambient temperature.
