Handling Qualities Evaluation of XV-15 Noise Abatement Landing Approaches Using a Flight Simulator

Abstract

A piloted simulation experiment was conducted in the Vertical Motion Simulator to evaluate the handling qualities of noise abatement approach procedures for a civil tiltrotor. Approach and landing procedures flown on the XV-15 tiltrotor research aircraft were evaluated in the simulator by a larger pilot population. The impact on handling qualities of attitude stabilization control response and winds and turbulence were studied. Evaluations by nine pilots upheld rating commentary by the two pilots who flew the acoustic measurement flight tests. Simulation evaluations judged the noise abatement approach profile handling qualities satisfactory for the XV-15 in calm air, degrading into adequate handling qualities in winds and turbulence. Attitude stabilization assisted tracking precision, but at the expense of increased workload to compensate for aircraft trim changes associated with flap deflection and large nacelle movements.
