AOC, ARGUS, IS-BAO, Wyvern: what they guarantee
Private jet operator certification
The certifications that demonstrate an operator's safety credentials, and how to ensure you fly with an audited company.
Why operator certification is the real safety guarantee
When you book a flight, you do not board the aircraft of a broker or a platform: you board that of an operator — the company that owns the aircraft, employs the crew, and assumes responsibility for the flight. It is therefore their certification that determines, in practice, your level of safety. If the distinction between the different players is still unclear, our article on the difference between an operator and a broker explains it clearly.
An operator’s safety rests on two complementary tiers. The first is mandatory and regulatory: the air operator certificate. The second is voluntary and more demanding: independent safety labels (ARGUS, IS-BAO, Wyvern). Understanding what each one guarantees tells you what you should require — and why a good broker never books blindly.
The AOC: the mandatory regulatory foundation
The Air Operator Certificate (AOC) is the authorisation that every company must hold to carry passengers for remuneration. In Europe, it is issued by national civil aviation authorities under the EASA framework, in accordance with the Part-CAT rules (commercial air transport). In the United States, the equivalent for charter operations falls under the FAA’s Part 135 rules.
In concrete terms, obtaining and maintaining an AOC requires the operator to demonstrate continuously that:
- their aircraft are maintained in accordance with manufacturer-approved maintenance programmes;
- their crews are qualified, trained, and subject to strict limits on flight time and rest;
- their organisation has operating procedures, emergency management, and safety oversight in place, all in compliance with regulations.
This is the non-negotiable minimum. A flight carried out without a valid AOC is not a legal commercial flight, and no serious broker should ever propose one to you. But the AOC guarantees compliance, not excellence: two operators may both hold one while having very different safety cultures. This is where independent audits come in.
Independent labels: a step above
Beyond regulation, private organisations audit operators on a voluntary and paid basis. These labels carry no legal force, but they have become the industry benchmark for distinguishing a genuinely rigorous company from one that does only the bare minimum. Three standards dominate the market.
ARGUS
ARGUS International rates operators across several levels: Gold, Gold Plus, and Platinum (with a Platinum Elite tier at the top). The assessment covers safety history, insurance, pilot qualifications, and — from Gold Plus level onward — an on-site audit. The Platinum level additionally requires a mature safety management system (SMS). A distinguishing feature of ARGUS: ongoing monitoring of operators between audits through its CHEQ database, enabling rapid response to any new information.
Wyvern
Wyvern, the oldest of the three (established in 1991), is recognised for the depth of its audit. Its flagship label, Wingman, is awarded following a document review and an on-site audit. Its defining feature: Wyvern verifies each pilot individually through its PASS database, not only the company as a whole. In practice, the specific crew assigned to your flight can be checked before departure.
IS-BAO
IS-BAO (International Standard for Business Aircraft Operations) is published by the IBAC, based in Montreal. It is not a rating system but an international safety management standard, structured in three stages: Stage 1 establishes the SMS framework, Stage 2 verifies it in practice, and Stage 3 confirms that the safety culture is fully embedded in day-to-day operations, with demonstrated continuous improvement. It is the international benchmark, particularly prevalent in Europe, the Middle East, and Asia.
These three labels do not evaluate the same things (track record and data for ARGUS, pilot-level verification for Wyvern, SMS maturity for IS-BAO). This is precisely why the most serious operators often hold several simultaneously, which signals a genuine commitment to safety.
How to verify that an operator is properly certified
Verifying an operator’s certification is possible, but requires knowing where to look:
- Ask for the AOC: its number and the authority that issued it. This is the baseline, and it must be currently valid.
- Ask for details of any independent labels: ARGUS Platinum, Wyvern Wingman, IS-BAO Stage 2 or 3. Be wary of vague formulations such as “audited operator” with no indication of the level.
- Cross-reference with the auditing bodies: ARGUS, Wyvern, and IBAC all maintain up-to-date lists of certified operators. A status can be verified directly.
- Ask the right questions about the specific flight: which aircraft, what maintenance programme, what minimum flight hours for the assigned pilots, and what happens in the event of an aircraft substitution.
For a traveller who does not know the market, this process is time-consuming and technical. This is exactly the added value of a specialised intermediary.
Why a good broker only works with audited operators
An independent broker like Private Jets Connect owns no aircraft: its role is to select, for each flight, the best operator on the market. And that selection always starts with safety. Before any discussion of price, a serious broker rules out any operator without a valid AOC and systematically favours those holding up-to-date independent audit labels.
This verification is carried out in advance, for every flight — not once and for all. You therefore do not need to assess the credibility of an unknown foreign company on your own: the broker does it for you. Screening operators is their profession. This is one of the core responsibilities detailed in our guide on the role of a private jet broker.
To be clear about the scope: this article addresses certifications at the company and aircraft level. Passenger-side checks, insurance questions, and overall private jet safety statistics are covered in dedicated articles; for a full overview, see our private jet safety guide.
Conclusion
The safety of a private jet flight is determined first and foremost by the operator. The AOC guarantees minimum regulatory compliance, while independent labels (ARGUS, IS-BAO, Wyvern) attest to a superior, audited safety culture. You can verify these elements yourself, but the simplest approach is to entrust this check to an independent broker who only books with certified and audited operators. That is Private Jets Connect’s approach, on every flight.
Frequently Asked Questions
Everything you need to know about our services
What is an AOC (Air Operator Certificate)?
The AOC (Air Operator Certificate) is the authorisation issued by the civil aviation authority (EASA and national authorities in Europe) that permits a company to carry passengers for remuneration. It certifies that the operator meets standards for maintenance, crew training, and operations (Part-CAT in Europe). Without an AOC, no legal commercial flight is possible: it is the mandatory foundation of safety.
What is the difference between ARGUS, IS-BAO, and Wyvern?
These are three independent and voluntary safety audits that go beyond the regulatory minimum. ARGUS rates operators (Gold, Gold Plus, Platinum) on their track record, insurance, and crews, with ongoing monitoring. Wyvern (Wingman label) additionally verifies each pilot individually through its PASS database. IS-BAO is an international safety management standard (SMS) structured in three stages. The best operators often hold several of these labels simultaneously.
How do I verify that a private jet operator is certified?
Ask for the AOC number and the issuing authority, then request details of any independent labels held (ARGUS Platinum, Wyvern Wingman, IS-BAO Stage 2 or 3). This information can be verified directly with the auditing bodies. In practice, an independent broker carries out this check for you before every flight proposal.
Does the broker guarantee the operator's certification?
A serious broker only works with operators holding a valid AOC and, in the great majority of cases, independent audit labels. They verify these criteria in advance, for every flight. This is precisely the value of using an intermediary: you do not have to assess the credibility of an unknown company yourself.
