Human Factors Problems in General Aviation

Approximately 80% of general aviation accidents in the past decade have been attributed to errors made by pilots. For this reason, the most promising approach to making substantial improvements in general aviation safety is through the systematic study of factors affecting the performance of general aviation pilots (i.e., human factors) and use of the resultant information to enhance pilot performance. In recognition of the need for comprehensive information to aid in the planning of such studies, the major objective of the work reported here was to identify and analyze human factors design issues related to the major performance problems of general aviation pilots. Thirty- five such issues were identified, primarily through the review of the human factors, aircraft accident, and general aviation literature. The analysis and discussion of these issues was structured through the use of a conceptual model of the components of the general aviation system. Six such components were identified--(1) aircraft, (2) airports, (3) aeronautical information systems, (4) the pilot certification and ratings, and (6) continuation training and recurrent proficiency assessments.
