The invention discloses a method for determining an isochronous point on an aircraft route and a method for selecting a landing preparation reference point. The method comprises the following steps: acquiring latitude and longitude coordinates of a starting point and an end point of a to-be-flied leg, and forming a leg route represented by the latitude and longitude coordinates based on the latitude and longitude coordinates; acquiring latitude and longitude coordinates and real-time wind power and wind direction information of a selected first reference point and a selected second reference point for landing, and determining an isochrone corresponding to the first reference point for landing and the second reference point for landing based on the latitude and longitude coordinates and the real-time wind power and wind direction information; and determining an isochronous point in the to-be-flied flight segment based on an intersection point of the isochronous line and each to-be-flied flight segment included in the aircraft route. The problems that the isochronous point determined by an existing method for determining the isochronous point on the aircraft route is not accurate enough, and the calculation process for determining the isochronous point is complex, so that the isochronous point cannot be rapidly and accurately determined under the emergency condition are effectively solved.
本发明公开了确定飞机航路上的等时点的方法及选取备降参考点的方法。所述方法包括:获取待飞航段的起点和终点的经纬度坐标,并基于其形成以经纬度坐标表示的航段路线;获取选定的备降第一参考点和备降第二参考点的经纬度坐标以及实时风力和风向信息,并基于其确定与所述备降第一参考点和所述备降第二参考点相对应的一条等时线;基于所述等时线与所述飞机航路中包含的各个待飞航段的交点确定为所述待飞航段中的等时点。有效解决了现有的用于确定飞机航路上的等时点的方法所确定的等时点不够精准,以及用于确定等时点的计算过程复杂而无法满足在紧急情况下快速准确地确定等时点的问题。
