HOLDOVER TIMETABLE (TYPE I, TYPE II, TYPE III, AND
TYPE IV FLUIDS)
Refer to FAA Notice 8900.196, dated 8-16-12 or later for
holdover timetables.
The length of time that deicing and anti-icing fluids remain effective is
known as "holdover time". The holdover timetables for Type I deicing,
and Type II, Type III, or Type IV anti-icing fluids are only an estimation
and vary depending on many factors (temperature, precipitation type,
wind, and airplane skin temperature). The holdover times are based on
the mixture ratio appropriate for the OAT. Holdover times start when the
last application has begun.
Guidelines for maximum holdover times anticipated by the FAA, in
coordination with Transport Canada (TC) and the SAE G-12 Aircraft
Ground Deicing Holdover Time Subcommittee generated the HOT
guidelines published in FAA Notice 8900.196 for Type I, Type II, Type III
or Type IV, and ISO Type I, Type II, Type III, or Type IV fluid mixtures.
Type I HOTs are a function of weather conditions and outside air
temperature (OAT) while the HOTs for Type II, Type III, and Type IV
fluids are primarily a function of the OAT, precipitation type and
intensity, and percent Freezing Point Depressant (FPD) fluid
concentration applied.
The SAE no longer publishes HOT guidelines.
