基于QAR数据的飞机拉平下滑段距离的影响因素

Influencing Factors of Aircraft Leveling Glide Distance Based on QAR Data

飞机着陆冲出跑道事件时有发生,分析影响飞机拉平下滑段距离的因素对飞行员理解和控制飞机着陆距离有正向帮助。本文先对飞机拉平下滑段的距离做了数学分析,再利用SPSS逐步回归分析A公司的239条着陆段QAR数据,其结果与数学分析一致,并依据结论对飞行员的操作提出了建议,对飞行员控制着陆距离有一定参考价值。

The event of an aircraft landing off the runway often occurs,and analyzing the factors that affect the aircraft′ s leveling of the glide path distance is positively helpful for pilots to understand and control the aircraft′s landing distance.This paper first makes a mathematical analysis of the distance of the plane′s flattening glide section,and then uses SPSS stepwise regression analysis to analyze 239 QAR data of the landing section of A company.The results are consistent with mathematical analysis,and based on the conclusions,put forward suggestions for the pilot′s operation,which has certain reference value for the pilot to control the landing distance.
