The invention provides a radio automatic tuning method and device for a helicopter flight management system, and the method comprises the steps: S1, a flight management system obtains the position information of a helicopter, and the position information comprises latitude and longitude; s2, searching a preset database by the flight management system, and determining whether the helicopter enters a coverage range of a second ground platform except the first ground platform or not; the first ground platform is the currently accessed ground platform; the preset database stores the frequency and the coverage range of each radio communication navigation ground station; and S3, if yes, switching the frequency of the airborne radio communication navigation equipment to the frequency of the second ground station. Frequency tuning can be automatically carried out on radio communication and navigation equipment according to the current position of the helicopter, the operation automation degree in the flight process is greatly improved, and the operation load of a unit is effectively reduced.

    本发明提供一种直升机飞行管理系统无线电自动调谐方法和装置,该方法包括:S1、飞行管理系统获取直升机位置信息,位置信息包括经纬度;S2、飞行管理系统查找预设数据库,确定直升机是否进入除第一地面台外的第二地面台的覆盖范围内;第一地面台为当前接入的地面台;预设数据库中存储有各无线电通信导航地面台的频率以及覆盖范围;S3、若有,则将机载无线电通信导航设备的频率切换至第二地面台的频率。可以根据直升机当前位置,自动对无线电通信和导航设备进行频率调谐,极大提高了飞行过程中的操作自动化程度,有效降低机组的操作负荷。
