Description

technical field [0001] The invention belongs to the technical field of aircraft ground icing detection, and in particular relates to a method, device, system and computer equipment for aircraft ground icing detection. Background technique [0002] Aircraft play an important role in long-distance transportation. Whether it is passenger travel or material transportation, it can achieve high-speed and high-efficiency. While airplanes bring great convenience to people, flight safety is also highly valued by airlines and consumers. Aircraft icing will seriously affect the performance of the aircraft. The surface of the aircraft facing the airspeed direction is very easy to accumulate ice, such as the nose, pitot tube, windshield, engine intake, fairing leading edge, wing leading edge , the leading edge of the vertical tail, etc. Ice accumulation on the pitot tube and antenna will directly destroy its normal function, causing serious problems such as instrument failure and commu...
