Icing Considerations for HALE (High Altitude, Long Endurance) Aircraft
Abstract
Although a low probability event, ice accretion does present a major obstacle to safe aircraft operations. In this report, the character of the aircraft icing environment is explored in terms of key meteorological and aerodynamic factors as related to the HALE (High Altitude, Long Endurance) aircraft. The distribution of icing in the atmosphere, mainly a function of temperature and cloud structure, is presented. Ice forecasting techniques and icing instrumentation are discussed as viable approaches for minimizing potential aircraft icing hazards. It is concluded that an onboard ice accumulation detector in combination with ground-based remote sensing instrumentation would provide the best capability icing forecasting program, which is often both effort- and time-efficient, is recommended. Keywords: Icing instrumentation, Icing characteristics, Icing forecasting, Supercooled clouds.
