摘　　要：飞机从一个航段飞向下一个航段时,需要对下个航段是否激活进行判断。提出了一种新的飞行计划航段自动激活方法,通过获取飞机当前位置及其磁差,并结合临近的3个航路点对应位置的磁差经纬度,分别计算3个航路点与飞机位置对应的磁航向角,通过磁航向角之间做差进行比较,进而判断是否被激活。算法推导完成后,通过基于模型的系统工程工具SCADE SUITE进行了建模,并结合杰普逊航图进行了实际数据采样与仿真。仿真结果表明:该航段自动激活方法能够有效稳定地激活下一航段,比传统方法计算简便,方法实用有效。已在实际飞行中成功应用,达到了预期效果。When the aircraft files from one segment to the next one,it needs to judge whether the next segment is activated or not.In this paper, a new method is proposed for automatic activation of planned flight segment.By obtaining the current position and magnetic deviation of the aircraft,and combining with the longitude and latitude of magnetic difference of the corresponding positions of the adjacent three waypoints, the magnetic heading angles corresponding to the three waypoints and the aircraft position are calculated respectively.The difference between the magnetic heading angles is compared to determine whether it is activated or not.After the algorithm derivation is completed,the model is built based on SCADE SUITE,and the actual data sampling and simulation are carried out by using the JEPSSON chart.The simulation results show that: 1) This method can activate the next segment stably and effectively;and 2) It is practical and effective,and is simpler in computation compared with the traditional methods.The method has been used successfully in actual flight and has achieved the expected effect.
