Individual Latent Error Detection (I-LED): Making Systems Safer

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
