ILS进近飞行程序高度损失余度影响因素仿真研究

Simulation Study on Factors Affecting Height Loss Margin in ILS Approach Flight Procedures

针对国内飞行程序超障计算准则方面定量研究较少的问题,并为真实反映各类飞机在ILS进近程序中的高度损失(HL)余度数值,本文通过构建飞机着陆—复飞过程的仿真框架,考虑了影响HL值的因素,通过运动学仿真得出ILS进近中不同类别典型航空器的HL值,并与现有飞行程序设计规范中的值进行比较分析。通过模拟计算和结果分析,结果表明使用气压式高度表时,现有规范的公布值与仿真结果较为吻合,但在使用无线电高度表时,现有规范的公布值与仿真结果存在一定差异。

This paper addresses the issue of limited quantitative research on the obstacle clearance calculation criteria for flight procedure in domestic aviation.To accurately reflect the height loss(HL)margin values of various aircraft in the ILS approach procedure,this paper constructs a simulation framework for the aircraft landing-go-around process,considers factors influencing the HL values and conducts kinematic simulations to determine the HL values for different types of aircraft in ILS approaches.These values are then compared and analyzed against the values in existing flight procedure design specifications.Through simulation calculations and result analysis,the findings indicate that the published values in the existing specifications are consistent with the simulation results with barometric altimeters.However,there are some discrepancies between the published values and simulation results with radio altimeters.
