针对指数法评估飞机空战能力的不足，研究了气象环境对飞机作战效能的影响，分析了综合指数模型中飞机操纵性能、态势感知能力、火力性能受不良气象条件的影响，建立了不良气象环境下的飞机系统空战效能评估模型。最后以3种机型的空战能力评估为例进行计算，验证了所建模型是合理、可行的。

Considering the deficiencies of the exponent model in evaluating the air combat capability of airplanes the effect of weather on the aircrafts operational efficiency was studied.The effect of bad weather on the steering capability situation awareness capability and firepower performance of the airplane in the synthesized index model was analyzed.And a new model was established to evaluate the aircrafts operational efficiency under adverse weather.Air combat capability assessment was made taking 3 types of airplane as example and the result showed that the model is reasonable and effective.
