起飞是整个飞行过程中最关键的阶段之一,飞机此时如果在结冰情况下运行会给飞行安全带来很大的威胁。因此,了解机翼污染情况下的飞机失速保护功能的局限性,并正确地掌握飞机的除冰和防冰程序。飞机在其关键表面带有冰雪霜的情况下起飞,可能造成严重的飞行事故。1982年1月,一架波音737飞机在华盛顿机场起飞后坠毁。当时正下着小雪,环境温度是-7℃,事故原因是“飞机在机翼有雪的情况下起飞,机长试图利用前面DC-9飞机发动机的排气吹走机翼上的积雪;机组在结冰条件下没有使用发动机防冰,导致发动机仪表出现 Take-off is one of the most crucial stages of the flight. If the aircraft is operating under freezing conditions, it will pose a great threat to flight safety. Therefore, understanding the limitations of aircraft stall protection in the case of wing pollution and proper understanding of aircraft deicing and anti-icing procedures. Aircraft taking off with frost on their key surfaces can cause serious flight accidents. In January 1982, a Boeing 737 crashed after taking off at Washington Airport. At that time, there was light snow and the ambient temperature was -7 ° C. The reason for the accident was that ”the aircraft took off with the wing in snow and the captain tried to blow away the snow from the wing with the exhaust of the front DC-9 aircraft engine; The unit did not use engine anti-icing in icing conditions, resulting in the appearance of an engine meter
