IOSA Standards Manual (ISM)

In today’s dynamic environment, airlines need an IATA Operational Safety Audit (IOSA) that focuses on safety risks, specific to the auditee, rather than applying a "one-size-fits-all" approach. Risk-based IOSA delivers an audit scope that will be tailored for each airline. Furthermore, the new approach introduces a maturity assessment of the airline's safety-critical systems and programs. Focusing on pertinent safety risks, while maintaining a baseline of safety, Risk-based IOSA increases the effectiveness of the audit and contributes to the overall industry goal of reducing the accident rate.

As a key foundational element of  the IOSA program the IOSA Standards Manual (ISM) contains the IOSA standards, recommended practices (ISARPs), and associated guidance material, which make up the assessment criteria for the IOSA Audit, and that is used by operators to successfully prepare for an audit.

The ISM is designed to assist operators in creating accuracy and operational efficiencies in preparing and conducting ongoing safe operations, based on the IOSA standard. The ISM is available in two formats for ease of use and integration.
