Book Description
A theoretical analysis was made to investigate the performance and acceleration-restriction capabilities of a normal-acceleration command control system in a fighter airplane. Several combinations of pitching velocity and pitching acceleration were investigated as feedback quantities in combination with normal acceleration.

Book Description
The present study is concerned primarily with methods of reducing or eliminating automatic-interceptor tracking errors that are caused by target maneuvers. The flight-test phase of the study was made with an automatic interceptor system. This system utilized an error integrator in the deflection channel of the automatic system to eliminate steady-state errors caused by steady target maneuvers.

Book Description
The effects of control system dynamics on the longitudinal flying qualities of fighter airplanes were investigated in flight, using the USAF/CAL variable stability T-33 airplane. Two pilots evaluated a total of 57 different combinations of control system and short-period dynamics at two flight conditions, while performing tasks representative of the 'combat' phase of a fighter's mission. The pilot rating and comment data from this investigation indicate that the dynamic modes of the flight control system can cause serious flying qualities problems, even if the short-period mode is well behaved. The data do not correlate with the control system requirements of MIL-F-8785B. In addition, the data demonstrate that the C* criterion does not adequately account for the effects of control system dynamics. Pilot-in-the-loop analysis of the data is shown to describe effectively the pilot's difficulties in control of pitch attitude, providing insight into how the pilot flies the airplane. A design criterion, based on this analysis, is shown to be applicable to a wide range of short-period and control system dynamics. A simplified version is also presented to provide the designer with preliminary estimates of flying qualities.
