Line Operations Safety Audit (LOSA) Training

TACG offers LOSA training and program implementation for airline, business aviation/charter, helicopter, cabin, ramp, maintenance, and military operations

A Line Operations Safety Audit (LOSA) is a formal process that requires expert and highly trained observers to observe operations in real-time and to collect safety-related data on environmental conditions, operational complexity, and human performance.

LOSA is seen as an important way to help develop countermeasures to operational errors. It involves a structured program of observation of front line activities built around the Threat and Error Management (TEM) concept. It aims to identify threats to operational safety, identify and minimize the risks which are the origin of such threats, and implement measures to manage the human error aspects of the residual risk. LOSA provides a way to assess the level of organizational resilience to systemic threats in accordance with the principles of a data-driven approach (Source:

TACG offers LOSA training and program implementation to a wide variety of aviation organizations. Our LOSA services are scalable to organization size. Whether you just need a LOSA course, or a full implementation package (where we do most of the work), our fees are very affordable.

  • LOSA is predictive (when you are being predictive you are being very proactive!)
  • LOSA incorporates the principles of Threat and Error Management
  • LOSA is complementary to other reactive/proactive/predictive safety data collection programs
  • LOSA is viewed very favorably by insurance companies and most offer reductions in insurance premiums for organizations that have a LOSA program in place
  • LOSA is an important element of your Safety Management System
  • CRM, TEM, and Human Factors courses can be continuously updated using data obtained from your LOSA results (evidence-based training)
  • LOSA was originally developed for the flight deck, but is now available in other areas such as cabin, helicopter, ramp, and maintenance operations
