起飞一发失效应急程序设计难点的研究分析

Study on Overall Design Specifications of EOSID

随着航空运输业的不断发展,起飞性能的经济性变得更加突出,制定起飞一发失效应急程序具有安全和效益两方面的重要意义。通过对起飞一发失效应急程序的基本概念和意义的分析,结合工作实际,重点对实际设计中的难点和要点进行了较为深入的分析研究,包括障碍物的选取和分析、决策点的确定和分析、转弯策略的选取和分析等问题,其中转弯时爬升梯度损失的计算、转弯速度的确定、风的修正等技术性问题是从实践中总结归纳出来的,特别是对决策点的确定、飞行轨迹的模拟、飞行轨迹与地形图的叠加、转弯策略的选取、风的修正等问题提出了解决方法。

With the development of aviation transportation, the economy of take-off performance becomes more outstanding, which makes the EOSID with the significance of both safety and efficiency. By analyzing the basic concept and significance of the EOSID combined with work reality, focusing on the difficulty in actual designs, the key points are discussed in depth, including the selection of the obsta- cles, the determination of decision points, strategy selection and analysis of the problems of turning, in which the climb gradient loss calculation in tuming, the determination of turning speed, the wind correc- tion and other technical problems are summarized from practice. The author puts forward the solutions especially on how to determine the decision points, trajectory simulation, flight trajectory and the topographic map superposition, selection of strategy of turning and the wind correction problem.
