摘　　要：本文针对特种飞机在简易机场着陆面临的问题,提出了一种虚拟仪表进近引导技术,根据跑道信息和设置的下滑路径角,构建虚拟进近路径,并计算飞机相对虚拟进近路径的虚拟方位偏差和下滑偏差,自动引导飞机到达决断高度。设计了虚拟进近系统并开展了仿真验证,结果表明虚拟仪表进近引导技术可达到类精密进近的同等精度水平,能够提高特种飞机着陆的安全性,减轻飞行员操作负担。Aiming at the problem of special mission aircraft landing at airstrip,a virtual instrumental approach guiance technology is proposed.According to runway information and glide angle set up by the aircrew,the virtual approach path is built,and the virtual azimuth deviation and glide deviation related to the virtual approach path is calculated and sent to the autopilot,so that the aircraft is guided to decision height.A virtual approach guidance system is designed,and simulation verification is performed.The simulation results show that guidance precision of the virtual instrumental approach guidance technology has reached a similar accuracy level with a typical APV(Approach with Vertical Guidance),and it can enhance the landing safety of special mission aircraft and reduce the workload of the aircrew.
