Description

The present study evaluated the utility of a Flight Test Trajectory controller, a special purpose display, in improving pilot performance and reducing workload during difficult test maneuvers. Algorithmic controlled indicators presented focally and in an integrated manner, information about pitch and roll stick control and Mach error. The display thus functioned as a flight guidance system, with the pilot's task being to reduce the error signal.

In two simulated maneuvers, performance, as measured by time to achieve condition and elapsed time on condition, was facilitated by the trajectory controller when compared with performance using conventional instrumentation. In addition, pilot workload, measured by performance on two secondary tasks was significantly reduced in the trajectory display condition.
