摘要
以微分形式 ,推导出了在停车迫降中 ,逆风会使下滑距离缩短、飞机四转弯改出位置后移两种情况下四转弯改出高度的增量公式及计算方法。通过实例进行了定量分析 ,给出了逆风使下滑距离缩短和航线四转弯改出位置后移而使四转弯改出所需高度增加的一般规律 ,为成功实施迫降 ,保证飞行安全 ,提供了准确的理论依据。
The paper gives a formula and a calculating method for the increased value of final turn altitude in dead engine landing on two different conditions:head wind makes the gliding distance shortened,head wind makes the position of final turn move backward.Quantitative analysis is done through several practical examples,and a general law is found out for the needed increasement of final turn altitude in the above two cases,so the paper can provides an accurate theoretical basis for the successful performance of forced landing and the ensured flight safety.
