Research On Virtual Reality Verification Method Of Engine Out Standard Instrument Departure

Engine out Standard Instrument Departure(EOSID) is developed to avoid obstacles, improve takeoff weight limit, and meet the safe obstacle clearance requirements on engine out condition during takeoff stage, whose path and plan is different with that of Standard Instrument Departure(SID). With the increase of complex airports, EOSID is more and more widely applied. Currently, research works on EOSID is very absent, mainly focus on emergency procedures design, which is primarily manually designed by performance engineers. Meanwhile, the verification on EOSID just stays on the combination of chart drawing and on-the-spot flight verification, for the virtual flight demonstration on EOSID, the relative research and supporting system is very rare.Currently, the development of Unmanned Aerial Vehicle(UAV) path planning and virtual reality technology is very mature. The path planning technology of UAV is applied to plan the path of EOSID automatically, and the virtual reality(VR) verification method of emergency procedures is studied. The research work includes the following. First, EOSID path planning is studied, by applying sparse A* algorithm, an emergency departure path from the end of airport runway to the designated departure point is generated, and the path is track datum of the VR verification system of emergency departure. Then, basic data of EOSID verification system, which including the flight data of official emergency departure, are prepared and analyzed. And terrain and departure obstacle data are also generated. Finally, an EOSID verification system is designed. Both the official emergency departure flight data and the planned emergency procedures track is verified in the departure verification system based on the Visualization of terrain and departure obstacle.
