LOSA is Proactive Risk Management
A Line Operations Safety Audit (LOSA) is a proactive, non-punitive safety management tool used in aviation to collect data on operational performance during normal operations. Unlike traditional audits that focus on compliance, LOSA involves trained observers—often peers like pilots or flight attendants—who monitor routine flights from the jump seat to record crew behavior, decision-making, and the management of threats and errors. It is built around the Threat and Error Management (TEM) framework, which identifies threats (external risks like weather), errors (human mistakes), and undesired states (unsafe conditions) to enhance safety.
