Recommended Practices for Human Factors Evaluation Development Process for Advanced Avionics

Abstract

Advanced avionic systems are currently being developed for use in general aviation aircraft. The avionics include both primary flight displays and multi-functional displays. In order to support the human factors development of such displays, a research project was undertaken to review current FAA guidelines relating to human factors requirements necessary for certification, and other relevant FAA documentation. FAR Part 23 is commonly used for certifying avionics for general aviation aircraft. Specifically, Part 23 is used for normal, utility, acrobatic, and commuter category aircraft. Part 23 was reviewed and the human factors requirements listed in this document. The human factors requirements are presented in the regulations in very general terms, and focus primarily on presentation of warning information, location of instruments, visibility of instruments, pilot workload, and warning, caution, and advisory light color schemes. Little guidance is given in the regulations on how to measure, test and satisfy the human factors related regulations.
