Study on Methods of Aircraft Icing Diagnosis and Forecast
Abstract：The 150 pilot reports （PIREPs） of icing conditions in Shandong province were collected. Aircraft icing diagnosing and forecasting experiments were carried out separately with simulation data of physical quantity field and three icing algorithms （ Ic, RAP, RAOB） , and the accuracy rates of the three algorithms were verified. To get better accuracy rate and lower missing rate, the Ic and RAOB algorithms were get improved by readjusting icing temperature and humidity thresholds, or corresponding coefficient. The accuracy rate of the new Ic algorithm was nearly increased by 10% in condition of keeping a lower missing rate, and the missing rate of the new RAOB algorithm was nearly decreased by 12% in condition of keeping a good accuracy rate.
