摘　　要：机载地图作为航空电子设备的重要组成部分,在飞行过程中扮演着辅助导航的关键角色。而航线剖面作为机载地图的一部分,重点表示航线高度、航线下地形高度及其相对位置特征信息。本文创新性地引入垂点、到点序号概念,提出了一种能实时、动态表征航线、地形和飞机位置三要素之间的相对位置情况的航线剖面绘制方案。该方案能让飞行员动态地观察到飞机相对地形位置及航线偏离情况,提升飞行效率和安全。As an important part of avionics equipment,the onboard map plays a key role in assisting navigation during flight.The route profile,as part of the onboard map,focuses on indicating the route altitude,the terrain altitude under the route,and its relative position characteristics.The concepts of vertical point and arrival point number are innovatively introduced,and a route profile drawing scheme is proposed that can dynamically characterize the relative position of the route,terrain and aircraft position in real time.This scheme allows pilots to dynamically observe the aircraft's relative terrain position and route deviation,improving flight efficiency and safety.
