The IATA Operational Safety Audit (IOSA) programme is an internationally recognised and accepted evaluation system designed to assess the operational management and control systems of an airline. IOSA uses internationally recognised quality audit principles and is designed to conduct audits in a standardised and consistent manner.

The IATA Safety Audit for Ground Operations (ISAGO) is meant to improve safety and reduce cost in the ground environment. Based on the IATA Operational Safety Audit (IOSA) framework, ISAGO aims to implement a formal, systematic process to manage operational risk and safety, reducing accidents, incidents and injuries.

One of our core consultancy activities is IOSA and ISAGO audit preparation and post-audit consultancy. TGB Aviation assists airlines in managing IOSA compliance process and in closing the findings after a gap-analysis or final audit. Other consultancy services that TGB offers enable airlines to comply with the applicable regulations and standards by providing assistance and support on various organizational and operational issues.
