An indispensable tool for the development of a carrier landing control system is the linearized kinetics model of carrier-based aircraft, which is required to accurately describe aircraft air turbulence responses because the approach-path turbulent atmosphere is the major source of glidepath and touchdown errors. The conventional method of longitudinal linear modeling fails to correctly emulate aircraft groundspeed variations during final carrier approach. Considering the fact that control requirements related to the velocity are stringent, an improved linearization method is proposed. It compensates the cross-disturbance effects of wind gust horizontal and vertical components on airspeed and angle of attack, besides requantifying the induced force transient along the flight path. This technique, as applied to an example carrier-based aircraft model, leads to a linearized final-approach kinetics model with a significantly enhanced capability on analyzing aircraft groundspeed deviation in the carrier air-w...
