Abstract:

A flight investigation of fighter side-stick controller force- deflection characteristics was performed using the USAF NT-33A variable stability airplane equipped with a variable feel side stick. The simulated airplane and control system characteristics were representative of a modern high performance fighter employing a side-stick controller. Up-and-away tasks including formation, air-to-air tracking and acrobatic maneuvering, and landing approach tasks were evaluated by two pilots. Four values of nonlinear pitch and roll side-stick force-command gain resulting in different response per force ratios were evaluated with different side-stick force-deflection gradients, including a rigid side stick.
