The Enhancement of Line Operations Safety Audit for Safe Flight Operation

Purpose: Line Operations Safety Audit (LOSA) has reduced errors by detecting and managing threats and errors of flight deck crew in the cockpit during normal flight operations. Airlines can understand the countermeasures and competencies of the crew and the success of error management. This paper introduces the advantages of LOSA and how LOSA data collection can be enhanced for the safety of flight operations. Methods: It analyzed the components of data collection tool in the International Civil Aviation Organization Doc 9803, LOSA manual to find out the deficiencies for enhancement. Results: Five suggestions are proposed in this study, codes for positive activities and the development of a form, the development of proactive strategies that predict threats in advance and manage the threats and management of errors, to describe the coding and narrative for successful briefings that manage threats and errors and codes for positive culture are required for successful LOSA data collection flight operations. Conclusion: Safety Management System, Threat and Error Management, LOSA, and other conventional safety tools manage safety based on risk or failure, so if we change the paradigm, we can train more safety-resilient pilots. The tragic outcomes such as accidents or incidents have the problem of low occurrence probability, but if we supplement and utilize LOSA data of normal flights, we can prevent accidents or nearaccidents in advance.
