The International Standards for Business Aviation Operations (IS-BAO) is an industry code of best practices developed by IBAC for the international business aviation community. It focuses on the promotion of high operational standards, supported by operational procedures, efficient training and centers on the establishment of a performance based SMS system based on ICAO’s Standards And Recommended Practices on SMS. Many regulating agencies, including EASA and the FAA, have recognized IS-BAO as a validation program to meet ICAO SMS standards. The OTAR, regulating business aviation in the British Oversee Territories as well as Isle of Man and the isle of Guernsey, have made the implementation of an SMS system mandatory and recommend IS-BAO as their benchmark standard. IS-BAO recognition is subject to an auditing process, which requires revalidation every 2 years.
