摘　　要：众所周知,盲降是各个机场最常用的进近方式。在盲降进近的最后阶段,飞机在进跑道之前,飞行员始终要参考仪表飞行,尽量将飞机的垂直航迹保持在下滑道上,以创造更好的入口条件。随着飞机距离跑道越来越近,飞行员目视飞行的比重越来越高,而在目视飞行时,正确的瞄准点对于飞行员控制飞机的下滑轨迹就显得尤为重要。为了找到正确的瞄准点,以西安机场05L/23R跑道为例,使用几何原理的方法对影响瞄准点的因素进行研究,并以两种极端的假设针对错误的瞄准点给飞行员操纵飞机落地带来的困难进行分析。As is known to all, many airports employ ILS as the most commonly used approaching mode. While in the final stage of ILS approach, the pilot should always fly with reference to the instrument before the aircraft enters the runway and try to keep the vertical track of the aircraft on the glide slope, so as to create better entrance conditions. As the aircraft gets closer to the runway, pilots depend more and more on visual flight during which correct aiming point is particularly important for the pilot to control the glide path of the aircraft. To find the correct aiming point, taking the runway 05L/23R of Xi’an Airport as an example, this paper employs the method of geometric principle to study the factors affecting aiming point and analyzes the difficulties brought by wrong aiming point upon pilots’ control of the aircraft during landing based on two extreme assumptions.
