What are the requirements for using the Ice Pellet Allowance Time Chart?
The ice pellet intensity, mixture of precipitation and intensity, and temperature must be listed in the chart. If it is not, allowance time cannot be used and takeoff is not authorized.
Allowance time cannot be extended by a Cabin Check.
If takeoff is not accomplished within the applicable allowance time, the aircraft must be completely deiced, and if frozen precipitation is still present, anti-iced again prior to takeoff.
