'And we were tired': fatigue and aircrew errors

Abstract

It is argued, on the basis information obtained by the NASA Aviation Safety Reporting System (ASRS), that the majority of errors made by aircrew members are cognitive errors, not control errors, and that a major contributing factor is fatigue. The ASRS incident reports indicate some aircrews often receive less than six hours of sleep, experience desynchronosis, and lack proper nutrition. The ways in which all these factors affect both individual performance and group (crew) performance are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
