TABLE 1
SAE TYPE I3 FLUID HOLDOVER GUIDELINES FOR WINTER 2008-2009
THE RESPONSIBILITY FOR THE APPLICATION OF THESE DATA REMAINS WITH THE USER
NOTES :
1 To use these times, the fluid must be heated to a minimum temperature providing 60.C (140.F) at the nozzle and an average rate of at least 1 litre/m2 (2
gal./100 sq. ft.) must be applied to deiced surfaces, OTHERWISE TIMES WILL BE SHORTER. 2 Heavy snow, snow pellets, ice pellets, moderate and heavy freezing rain, and hail. 3 Type I Fluid / Water Mixture is selected so that the freezing point of the mixture is at least 10.C (18.F) below outside air temperature. 4 Use light freezing rain holdover times if positive identification of freezing drizzle is not possible. 5 Ensure that the lowest operational use temperature (LOUT) is respected.
CAUTIONS
.
The only acceptable decision criterion, for takeoff without a pre-takeoff contamination inspection, is the shorter time within the applicable holdover time table cell.
.
The time of protection will be shortened in heavy weather conditions, heavy precipitation rates, or high moisture content.
.
High wind velocity or jet blast may reduce holdover time.
.
Holdover time may be reduced when aircraft skin temperature is lower than outside air temperature.
.
Fluids used during ground deicing/anti-icing do not provide in-flight icing protection.

TABLE 2 -Generic
SAE TYPE II FLUID HOLDOVER GUIDELINES FOR WINTER 2008-20091
THE RESPONSIBILITY FOR THE APPLICATION OF THESE DATA REMAINS WITH THE USER
NOTES :
1 Based on the lowest holdover times of the Type II fluids listed in Table 5-2.
2 Heavy snow, snow pellets, ice pellets, moderate and heavy freezing rain, and hail.
3 These holdover times only apply to outside air temperatures to -10.C (14.F) under freezing drizzle and light freezing rain.
4 Use light freezing rain holdover times if positive identification of freezing drizzle is not possible.
5 Radiational cooling during active frost conditions may reduce holdover times when operating close to the lower end of the outside air temperature range.
