"The primary objective of the 2023-24 holdover time (HOT) test program was to evaluate the performance of new deicing and anti-icing fluids over the entire range of conditions encompassed by the HOT Guidelines. The objective was met by conducting endurance time tests. The procedure for these tests consisted of pouring fluids onto clean aluminum test surfaces inclined at 10º. The onset of failure was recorded as a function of time in various precipitation conditions. A total of 926 tests were conducted with twelve fluids. The research conducted in the winter of 2023-24 resulted in the below changes to the HOT Guidelines for the winter of 2024-25"--Abstract, page v. Includes abstract in English and French.
