Rule fragmentation in the airworthiness regulations: A human factors perspective

Abstract

Human error has been identified as the primary risk to flight safety. Two of the more pervasive aspects of Human Factors encountered throughout the airworthiness regulations are error and workload. However, as a result of increasing organizational inter-dependence and integration of aircraft systems it is argued that the manner in which these issues are addressed in the aviation regulations is becoming increasingly incompatible with human and organizational behavior in an airline. Workload and error are both products of complex interactions between equipment design, procedures, training and the environment. These issues cannot be regulated on a localized basis. A more systemic, holistic approach to Human Factors regulation is required. It is suggested that a Safety Case-based approach may be better used as an adjunct to existing regulations for Human Factors issues. © 2011 Springer-Verlag Berlin Heidelberg.
