一直以来,通用航空事故及事故征候在民用航空飞行中都占有较大的比率。影响通用航空安全的因素主要有以下几方面:一是通用航空主要在对流层中、下层活动,易受乱流、云、降水、雾等天气的影响;二是低空飞行易受山区等复杂地理环境的影响;三是通用航空器体积小,抗风 All along, common aviation accidents and incidents account for a large proportion of civil aviation flights. The main factors affecting the safety of general aviation include the following aspects: First, general aviation is mainly affected by the weather in the middle and lower troposphere, such as turbulence, clouds, precipitation and fog; secondly, low-altitude flights are susceptible to complex geographical environments such as mountains The third is the general aircraft small size, wind-resistant
