A Flight Simulator Usability Assessment of a Multi-function Flight-planning and Navigation Display for General Aviation

Abstract

A human-factors and usability evaluation was performed on a beta version of a major manufacturer's flight-planning and in-flight navigation multifunction display in the Civil Aerospace Medical Institute's (CAMI's) Advanced General Aviation Research Simulator (AGARS), configured as a Piper Malibu (single-engine, complex aircraft). The evaluation was an open-ended process wherein data collection continued until consistent response patterns were uncovered. Data indicated general acceptance of the software package by the participating pilots. However, several recommendations for improvement arose from pilot consensus in the posttest questionnaire and interview that matched design criteria listed in a multi-function-display certification pocket guide being developed at CAMI. Changes to menu structure and data-entry logic were mentioned by nearly all of the participants, and included: navigation and route editing should occur on the same display page; a “back” or “undo” key is needed; and keys should be consistently placed across different pages. Findings are discussed in terms of cognitive loading, pilot expectations (stereotypes), and internal consistency.
