Background The flight management System (FLIGHT MANAGEMENT Computer System, FMS) is an important component of avionic devices, and can realize automation of various flight tasks and reduce manual workload. The FMS is a basic component of avionic equipment of a modern passenger plane, is responsible for functions of flight planning management, navigation, horizontal and vertical guidance, performance calculation and the like, can realize automation of various flight tasks, reduces manual work load, uses various sensors (such as GPS) to determine the position of an aircraft, automatically optimizes a flight path, improves flight efficiency and safety, and is used for flight planning navigation, including flight route, flight altitude and speed planning, flight route management, flight route point navigation and the like. The flight management system mainly realizes: the flight plan FLIGHT PLANNING the FMS allows the pilot to enter information such as start point, end point, waypoint and altitude, and generate a flight plan. Navigation (FMS) integrates a variety of Navigation sources such as GPS, inertial Navigation Systems (INS), radio Navigation (e.g., VOR, NDB, etc.), and provides accurate location and heading information. Real-time monitoring of aircraft heading deviation of the flight schedule. Flight management (FLIGHT MANAGEMENT) adjusts flight altitude, speed, and heading to maintain the flight at an optimal trajectory. And automatically executing turning, ascending, descending and other flying operations. Performance calculation (Performance Calculation) the FMS is able to calculate in real time fuel consumption, time of flight, optimum altitude, etc. information based on the aircraft model and current environmental conditions. Performance data is provided for the take-off, cruise, landing phases. Autopilot Autopilot Integration the FMS may be integrated with an autopilot system to automatically execute a flight plan, reducing pilot workload. The flight path display (FLIGHT PATH DISPLAY) displays flight path information and flight parameters on the cockpit display to help the pilot monitor the aircraft status in real time. In the aircraft cockpit, a pilot realizes the operation of a flight management system through operating a control display assembly (Control Display Unit ‌, CDU) device, wherein the CDU is an important operation device for the pilot to input flight data and is also a display device of an operation interface of the flight management system, and the display device consists of a square display and alphanumeric function keys and provides a necessary control interface for the pilot.
