This report presents the results of the Have MURDOC test management project. Have MURDOC demonstrated the use of a simple feedback flight control law that was designed to control flight and generate desired handling qualities throughout the design flight envelope. This was done by applying a pitch-rate feedback flight control law to the Variable In-flight Simulator and Test Aircraft (VISTA) and conducting 12 test flights with the controller, also known as a disturbance observer (DO), providing the input signal to the horizontal tail surfaces. The primary objective was to demonstrate longitudinal flight control using the DO. Programmable test input steps and doublets were used to measure the short period response of the VISTA at various altitudes and airspeeds and compare it to predictions based on simulation. Handling qualities were evaluated in the approach configuration as a buildup to demonstrating a low approach and runway touchdown.
