A large, new database of in-flight measurements of icing-related cloud and atmospheric variables in freezing rain and freezing drizzle conditions is used to help determine the range of temperatures, altitudes, exposure durations, icing intensities, precipitation drop sizes, and supercooled water concentrations to which aircraft could be exposed during flight in these conditions. In addition, three different models of cloud and precipitation drop size distributions are proposed for use in computing ice accretion rates and amounts on aircraft components or as a guide for designing water sprays to simulate freezing rain or freezing drizzle in icing wind tunnels or icing spray rigs.
