Adaptation of Line Operations Safety Audit (LOSA) to Dispatch Operations (DOSA)

Purpose: Dispatch Operations Safety Audit (DOSA) is a proactive and predictive method in safety management system that detects the capabilities and pitfalls of dispatcher performance. In this study, Dispatch-Line Operations Safety Audit is carried out in an airline and results are analyzed and discussed.Design/methodology/approach: The method of DOSA implementation for flight operations officers is similar to LOSA for flight crew.Findings: Results show that DOSA has an important effect on Threat and Error Management (TEM) in the Operations Control Center (OCC).Originality/value: Potential applications of this research include the better threat and error management in OCC with the implementation of DOSA as well as identification of threats and errors types for FOOs in OCC. Also distribution of threats and errors in different phases of dispatch shift is discussed, therefore syllabuses of training courses can be provided with respect to threat and error types for flight operations officers.

Developing a Single-Pilot Line Operations Safety Audit

A single-pilot form of the line operations safety audit was trialed with a mid-sized emergency medical service air operator using two observers with a sample of pilots flying 14 sectors. The conceptual basis for observing pilot performance and analyzing data was the threat and error management model, focusing on threats, errors, undesired aircraft states, and their management. Forty-six threats and 42 crew errors were observed. Pilots generally used sound strategies to prevent errors and to manage successfully those that occurred. Threats resulting from operational pressures were well managed. The study achieved its objective of determining whether a single-pilot line operations safety audit could be successfully developed and used as a basis for systematic data collection.
