Research of Handling Characteristics of Aircraft in Low Dynamic Pressure Situation

The handling characteristics degradation of aircraft in the low dynamic pressure situation can cause that the flight path angle cannot track the attitude angle,and then the safety of carrier landing is influenced.After enumerating and analyzing some historic explanations,a new and all-sided view concludes: when considering flight path angle response of aircraft in the low dynamic pressure situation,speed stability,flight path stability and maneuverability show all be concerned.And this analysis suggests that the automatic power compensator system(APCS) with constant airspeed actually corresponds with speed stability and flight path stability,and APCS with constant angle of attack is related to all the three factors.Numerical simulation also indicates the view is proper and feasible.
