The FAA last week published its de-icing holdover time (HOT) guidance for the upcoming 2015-2016 winter season. The document is designed to work in conjunction with the agency’s Revised FAA-Approved Deicing Program Updates Winter 2015-2016. There are no changes to the guidelines for active frost or Type I fluids.

There are now six changes to Type II HOT, including increases/decreases of up to five minutes, for some Type II fluids.
