Undetected human error in aircraft maintenance creates a latent error condition that can contribute to undesirable outcomes. Individual Latent Error Detection (I-LED) acts as an additional system safety control that helps an engineer recall past errors through environmental cues. This book addresses a gap in the human factors research and current safety strategies by exploring the nature and extent of I-LED and its benefit to safety resilience. The book will describe the I-LED concept using a systems perspective and propose practical interventions to be integrated within existing safety systems as an additional control to enhance resilience against human performance variability.

• Provides a new view of total safety based on enhanced resilience provided through the integration of I-LED interventions within existing safety systems
• Offers an in-depth exploration of the phenomenon of spontaneous recall of past event, leading to error detection and recovery of latent error conditions
• Discusses the application of Human Factors methods to conduct real-world observations in maintenance environments
• Describes the application of the systems view of human error to applied research
• Presents cost versus benefit analysis of safety interventions targeting latent error conditions

He is an air engineer in the Royal Navy where he currently works as a safety specialist delivering safety strategy across naval operations.

Professor Neville A Stanton, PhD, is a Chartered Psychologist, Chartered Engineer and a Chartered Ergonomist, and holds the Chair in Human Factors in the Faculty of Engineering and the Environment at the University of Southampton. He has degrees in Psychology, Applied Psychology and Human Factors and has worked at the Universities of Aston, Brunel, Cornell and MIT. His research interests include modelling, predicting and analysing human performance in transport systems as well as designing the interfaces between humans and technology. Professor Stanton has worked on cockpit design in automobiles and aircraft over the past 25 years, working on a variety of automation projects. He has published 30 books and over 250 journal papers on Ergonomics and Human Factors, and is currently an editor of the peer-reviewed journal Ergonomics. In 1998 he was awarded the Institution of Electrical Engineers Divisional Premium Award for a co-authored paper on Engineering Psychology and System Safety. The Institution of Ergonomics and Human Factors awarded him The Otto Edholm Medal in 2001, The President1s Medal in 2008 and The Sir Frederic Bartlett Medal in 2012 for his contribution to basic and applied ergonomics research. The Royal Aeronautical Society awarded him and his colleagues the Hodgson Prize and Bronze Medal in 2006 for research on design-induced flight-deck error published in The Aeronautical Journal. The University of Southampton has awarded him a Doctor of Science (DSc) in 2014 for his sustained contribution to the development and validation of Human Factors methods.
