"In the winter of 2018-19, Transport Canada (TC) and the Federal Aviation Administration (FAA) tasked APS Aviation Inc. (APS) to conduct natural snow characterization testing in order to investigate factors affecting variance in natural snow endurance time testing. APS conducted 139 natural snow characterization tests comprising 52 test runs during the 2018-19 and 2019-20 winters. The test runs consisted of standard endurance time tests with three reference fluids; additional environmental and fluid data was collected during each test to allow for investigation into factors that contribute to variance in natural snow endurance time testing. Data packages containing the full complement of environmental data were assembled for each of the test runs performed"--Abstract, page v (first section).
