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

Abstract

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: 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.
