The invention discloses a method for automatically selecting standby landing airports in an aircraft route. The method comprises the following steps of: determining a reachable geographical range of an aircraft based on the current position of the aircraft, a coverable flight radius and aircraft standby landing conditions, and selecting a plurality of reachable standby landing airports in the geographical range; aiming at a combination of each two airports in the reachable standby airports, respectively calculating an isochronous point corresponding to the combination and standby landing flight duration required for flying to the standby landing airports; dividing the current route segment into a plurality of sections by utilizing a plurality of isochronous points, and selecting two reachable standby landing airports with optimal standby landing flight duration and suboptimal standby landing flight duration as an optimal standby landing airport combination for each section; and outputting the optimal standby airport combination and the corresponding isochronous point. According to the invention, a better standby landing airport can be automatically selected for a plurality of standby landing airport options and a pilot is provided for prompting, so that the pilot can make an optimal standby landing selection in a convenient and simple operation mode.
本发明公开了一种用于自动选取飞机航路上的备降机场的方法,该方法包括以下步骤:基于飞机的当前位置、可覆盖的飞行半径及飞机备降条件,确定飞机可到达的地理范围,选取地理范围内的多个可达备降机场;针对可达备降机场中的每一种两个机场的组合,分别计算出与该种组合对应的等时点以及飞行至备降机场所需的备降飞行时长;利用多个等时点将当前航段划分为多个区段,针对每个区段选取备降飞行时长最优及次优的两个可达备降机场作为最优备降机场组合;输出最优备降机场组合及对应的等时点。本发明能够针对多个备降机场选项自动选取较优的备降机场并提供飞行员以提示,以便于飞行员以便捷简单的操作方式即可做出最优的备降选择。
