The International Standard for Business Aircraft Handling (IS-BAH) is a set of global industry best practices for business aviation ground handlers, which features at its core a safety management system (SMS). The IS-BAH follows the structure of the International Standard for Business Aircraft Operations (IS-BAO) Program and incorporates the NATA Safety 1st Ground Audit Program. IS-BAH is the global industry standard for handlers and operators around the world to meet the coming SMS requirements from the International Civil Aviation Organization (ICAO).
