THREAT AND ERROR MANAGEMENT (TEM) IN ATC
Threat and Error Management (TEM) is an overarching safety concept regarding aviation
operations and human performance. TEM is not a revolutionary concept, but one that has evolved gradually, as a consequence of the constant drive to improve the margins of safety in aviation operations through the practical integration of Human Factors knowledge.
TEM was developed as a product of collective aviation industry experience. Such experience
fostered the recognition that past studies and, most importantly, operational consideration of human performance in aviation had largely overlooked the most important factor influencing human performance in dynamic work environments: the interaction between people and the operational context (i.e., organizational, regulatory and environmental factors) within which people discharged their operational duties.
The recognition of the influence of the operational context in human performance led to the
conclusion that the study and consideration of human performance in aviation operations must not be an end in and on itself. With regard to the improvement of margins of safety in aviation operations, the study and consideration of human performance without context addresses only part of the larger issue. TEM therefore aims to provide a principled approach to the broad examination of the dynamic and challenging complexities of the operational context in human performance, for it is the influence of these complexities that generates the consequences that directly affect safety.
