Private Jet Safety Standards: AOC, IS-BAO, ARGUS and Wyvern Explained

The short answer

A safe private flight starts with one non-negotiable document: a valid Air Operator Certificate (AOC) held by the company that operates the aircraft. Everything else — IS-BAO registration, an ARGUS rating, Wyvern recognition — is a voluntary, independent audit that tells you more about how that operator manages safety. Good operators often hold one or more of these; none of them replaces the AOC.

Summary

1. Mandatory: AOC and operating authorisation from a national authority. 2. Voluntary audits: IS-BAO, ARGUS, Wyvern. 3. Practical checks: aircraft on the AOC, insurance, crew, and the operator named on your contract. 4. Red flags. 5. How VOLARÉ uses these checks.

1. The mandatory baseline: the Air Operator Certificate

In the European Union, commercial air transport operators — including on-demand business jet charter — must hold an AOC under the EU air operations rules published by EASA. The certificate is issued and overseen by the operator's national authority: for example ENAC in Italy, the DGAC in France or the Belgian Mobility and Transport FPS. In the United Kingdom the Civil Aviation Authority issues AOCs; in the United States on-demand charter is flown under FAA Part 135; in Singapore the CAAS is the certifying authority.

The AOC comes with operations specifications listing the aircraft the operator is authorised to fly commercially. An aircraft that does not appear there should not be flying your charter under that certificate.

2. Voluntary safety audits

IS-BAO

The International Standard for Business Aircraft Operations is administered by the International Business Aviation Council (IBAC). It is a safety management code of practice with three stages: Stage 1 confirms a safety management system is in place, Stage 2 that it is being used effectively, and Stage 3 that it is embedded in the operator's culture. Ask which stage the operator holds and when it was last audited.

ARGUS

ARGUS audits charter operators and publishes ratings of Gold, Gold+ and Platinum, with Platinum requiring the most extensive on-site audit. ARGUS is most widely used for North American operators but also audits operators elsewhere.

Wyvern

Wyvern publishes the Wyvern Wingman standard and recognises operators that pass its audit. Like ARGUS, it is particularly common in the United States.

How the audits compare in practice

Think of the AOC as a driving licence and the audits as an independent inspection of how the car is maintained and driven. An operator without any voluntary audit may still be fully legal; an audit simply gives you independent evidence beyond the minimum.

3. Practical checks before every flight

Confirm the operating carrier named on the charter agreement. Check that the aircraft registration appears on that operator's AOC. Ask for a certificate of insurance. Ask how many pilots will fly (two-pilot crews are standard on most business jets used for charter). If a broker or concierge is involved, the contract should still name the operator clearly.

4. Red flags

A seller unwilling to name the operator; an aircraft that is not on any AOC; a price far below comparable quotes with no clear explanation; pressure to pay before the operator is confirmed; or a 'private' arrangement where passengers share costs on an aircraft that is not certified for commercial flights. European business aviation associations have warned for years about this kind of illegal charter.

5. How VOLARÉ uses these standards

VOLARÉ is a private aviation brand, not an aircraft operator and not a certification body. We coordinate requests with licensed operators and partners; the selected partner may contact you directly, and the operator named on the contract remains responsible for the flight.

When we present an option, the operator and aircraft are named, and we ask for the documents above. If you are deciding between charter and other access models, read Membership, Charter or Fractional. To ask about a specific flight, open the concierge chat and describe your trip in your own words.
