Abstract:

This report documents the results of a study comparing forecasted aircraft icing conditions to pilot reports PIREPs of aircraft icing. Of the three operational forecast algorithms validated AF Global Weather Centrals RAOB routine, icing routines in the Navys NODDS, and TESS software, RAOB had the overall best comparison to the PIREPs and 6 percent of the type forecasts and 42 percent of the intensity forecasts agreeing with the reported icing. These percentages increase to 73 percent type and 53 intensity when considering only PIREPs from jet aircraft. The greatest degree of error was associated with forecasts of clear and mixed icing and icing of moderate intensity.
