IS-BAO Registration.

The benchmark for your business aircraft operations.

The International Standard for Business Aviation Operations (IS-BAO) is a worldwide recognised benchmark designed to support commercial and business flight departments in achieving a high level of safety and professionalism. In 2002 the International Business Aviation Council (IBAC) introduced IS-BAO as a safety code developed by the industry for the industry. Based on the International Standards and Recommended Practices of the ICAO, IS-BAO became a code of best practice for business aircraft operators all over the world. It is accepted as a means of compliance with ICAO Annex 6 Part II by several Civil Aviation Authorities. Furthermore the IS-BAO registration meets professional safety standards which are recognised within the implementing rules system of the EASA.

The outcome of the IS-BAO audit is a worldwide recognised registration which guarantees uninterrupted flight operations throughout Europe and the rest of the world. Up to now around 600 business aircraft operators are listed on the IS-BAO registry. Due to the fact that IS-BAO is based on ICAO and European aviation standards you can be sure that compliance with IS-BAO fulfils the latest requirements in the business aviation industry. IS-BAO is a continuously working standard that keeps your flight department on top level regarding the procedures and technologies.
