Full-Motion Aircraft Simulator Enhancements to Improve Cockpit Response to Pavement Roughness

As a preliminary to a project to measure pilot’s subjective response to vertical cockpit vibrations in ground maneuvers, the software of the Boeing 737 full-motion simulator located at the on Federal Aviation Administration (FAA) Mike Monroney Aeronautical Center in Oklahoma City has been modified to enhance the representation of cockpit response to pavement roughness. Modifications made to the software include the ability to load longitudinal elevation profiles measured on airport pavements, suppression of the generic roughness simulation models, and the addition of flexible body modes to the flight system dynamic simulation model. The modifications are described, together with the procedure used to transfer the computed vertical cockpit accelerations to the motion system. Cockpit accelerations computed in response to a number of test profiles are compared with accelerations measured with a physical accelerometer positioned below the pilot’s seat in the simulator cockpit. Comments made by two test pilots regarding the fidelity of the cockpit acceleration responses during taxiing, takeoff, and landing are reported. The pilots considered the responses to feel realistic except for the representation of background roughness, induced tire noise and the absence of responses to passing over centerline lights and concrete pavement joints.
