The invention belongs to the field of route planning, and particularly relates to a method and system for judging whether an aircraft is in a safe airspace or not. The method comprises the following steps: step 1, acquiring aircraft position information and limited airspace boundary information under a geographic coordinate system, and converting the aircraft position information and limited airspace boundary information under the geographic coordinate system into aircraft position information and limited airspace boundary information under a rectangular plane coordinate system; 2, judging whether the airplane is in a limited airspace or not; 3, calculating the minimum distance from the airplane to the limited airspace; 4, if the limited airspace is a safe area, whether the aircraft is in the safe airspace or not is determined according to a first judgment rate; and if the limited airspace is a non-safe area, determining whether the aircraft is in a safe airspace or not according to a second judgment rate. Whether the aircraft is in the safe area or not can be judged in real time, and warning prompt is carried out when the aircraft is in the non-safe area.

    本申请属于航路规划领域,特别涉及一种判断飞机是否处于安全空域的方法及系统。方法包括:步骤一、获取地理坐标系下的飞机位置信息以及限定空域边界信息,将地理坐标系下的飞机位置信息以及限定空域边界信息转换为平面直角坐标系下的飞机位置信息以及限定空域边界信息;步骤二、判断飞机是否在限定空域内部;步骤三、计算出飞机到限定空域的最小距离;步骤四、若所述限定空域为安全区域,则根据第一判定率确定飞机是否处于安全空域;若所述限定空域为非安全区域,则根据第二判定率确定飞机是否处于安全空域。本申请能够实时判断飞机是否处于安全区域,并在飞机处于非安全区域时进行告警提示。
