Comparison of Three Avionics Systems Based Upon Information Availability, Priorities and Accessibility

摘要

This study evaluates three avionics systems typically found in small general aviation aircraft. The evaluation included a traditional “steam gauge” airplane, an “intermediate” airplane equipped with traditional mechanical instruments along with a GPS-based moving map display and a technically advanced airplane equipped with a computer-based glass cockpit. We evaluated the avionics using a methodology described by Schvanevelt, Berringer & Leard (2004) which evaluates the availability and accessibility of information based upon the priorities pilots place upon the various information sources. The results show that computer-based avionics provide more information; however most of the additional information is located deep within the avionics’ menu structure.
