ABSTRACT

The accurate guidance provided by landing guidance system for carrier-based aircraft landing is very important for safe landing. Aiming at the problem that the guidance deviation of each equipment in the system affects the safety of landing, an index of the consistency of the landing glideslope indications is proposed. The relationship between "meat ball" offset and aircraft glideslope offset is analyzed and calculated. When the guidance errors of optical landing aids and midline cameras occur, the impact of landing point and glideslope offset of carrier-based aircraft is analyzed and simulated. The consistency of glideslope indications is analyzed, and the "meat ball" offset caused by the inconsistency of guidance between optical landing aids and midline cameras is simulated and calculated. Through simulation, consistency index can be used as a basis for system calibration.
