Abstract:
The meteorological factors directly affecting aircraft icing are air temperature, supercooled water content and the size of supercooled water droplets. The researches on the meteorological factors of aircraft icing are of great significance for flight safety assurance, aircraft airworthiness verification, weather modification and so on. In recent years, remarkable advances in the researches on this topic have been reported. A briefly comprehensive review for the advances in the researches on aircraft icing conditions is presented, which includes airborne observations, weather systems, satellite retrievals, forecast, and climate characteristics, as well as some related issues. The results of aircraft detection show that the temporal and spatial distribution of supercooled water is obviously uneven. On the basis of a large number of aircraft icing observation tests abroad, the icing environment is statistically analyzed, and a series of standards for aircraft icing airworthiness verification are formulated. The main weather systems that produce aircraft icing include the fronts, high troughs, and shear lines, and freezing rain often produces strong icing. It is the main trend to develop aircraft icing area recognition technology by integrating the advantages of multisource remote sensing data. The mesoscale model with the ability to predict cloud water explicitly provides a better tool for predicting aircraft icing. At the same time, the realtime ice potential system which integrates multiple monitoring data and model data is a new development direction.
