In November 2003, the National Transportation Safety Board recommended that the Federal Aviation Administration (FAA) convene a panel of aircraft design, operations, and human factors specialists to examine the feasibility of requiring the installation of low airspeed alerting devices on airplanes operating commercially under 14 C.F.R. Parts 121 and 135. The Board further recommended that if the panel determined such a requirement to be feasible, the FAA should establish requirements for low-airspeed alert systems. This paper discusses the reasoning behind these recommendations, explores relevant accident history from the Safety Board’s investigative records, and discusses shortcomings of an approach to cockpit design that relies on flight crew monitoring and artificial stall warnings for avoidance of low airspeed related accidents. Potential benefits and concerns associated with the installation of a new kind of low airspeed alerting device are also addressed.
