The 2009 accident involving Air France Flight 447 illustrates the gap between visual and auditory display design and implementation in commercial aircraft. By examining the successful evolution of Enhanced Ground Proximity Warning System (EGPWS) and Traffic Alert and Collision Avoidance System (TCAS) to incorporate both audio and visual alerting and resolution guidance to flight crews, a contrast is drawn with similar aids available in advance of aircraft upset episodes. A universal approach for future design should incorporate harmonized video and audio displays providing optimized alerting and guidance along with the latest in simulator training designed to emphasize aircraft state awareness degradations before a loss of control incident emerges. By promoting continued dialogue among the aviation community, it is hoped that the existing gap among research, design, and operations may be narrowed, resulting in flight deck audio displays optimized to support effective pilot performance.
