摘要
飞机活动半径与飞行等时点是在特殊或者紧急飞行情况下,根据飞机实际油量选定最有利的紧急备降机场,保证飞机在安全距离或者最短时间内在备降机场降落的一种紧急情况处置方法。本文通过理论分析和实例验证,提出在曲折航线飞行中,用实际飞行资料精确计算飞机活动半径和飞行等时点位置的新的计算方法。
The radius of action of an aircraft and the flight equal time point are essential in locating,for an aircraft in special or emergency flight, in light of the actual amount of fuel in the tank,a most advantageous alter- nate field where the aircraft can land within a safe distance and the shortest possible time.Through theorectical analysis and tests of living examples,this paper sets up a new method of precisely calculating the flight equal time point and the radius of action of an aircraft on a winding route by using actual flight information.
