IS-BAO, the International Standard for Business Aircraft Operations, is a voluntary safety standard for business aviation operators published by the International Business Aviation Council, IBAC. Launched in 2002 and built on safety management system principles, IS-BAO registration has three stages, from confirming an SMS exists, to managing risk effectively, to a fully embedded safety culture.

What does IS-BAO mean in practice?

IS-BAO is different from ARGUS and Wyvern in that it is a standard rather than a rating.

IBAC, which represents national business aviation associations, describes it as the only ICAO-recognised industry standards programme developed specifically for business aviation. An operator registers at Stage 1, 2 or 3 after an audit by an accredited auditor. Stage 1 confirms the safety management system infrastructure is in place. Stage 2 confirms safety risks are being managed effectively. Stage 3 confirms safety management is embedded in the business and a positive safety culture is sustained. IS-BAO is used by both commercial charter operators and private corporate flight departments, so an IS-BAO registration alone does not tell you that an operator holds an AOC. Check both. Stage 3 registration is a reasonable indicator of a mature safety organisation, but it is voluntary, paid for by the operator, and renewed periodically rather than continuously monitored.
