Helicopter charter safety: the UK rules that protect you

Key points

• The Civil Aviation Authority (CAA) regulates UK aviation, including every company that flies passengers for payment.
• A company that carries paying passengers needs an Air Operator's Certificate (AOC) and an operating licence from the CAA, and the CAA publishes a list of UK AOC holders.
• Commercial flights follow Part-CAT, which sets performance, training, checking and equipment standards; private flights with larger helicopters follow Part-NCC, which has no AOC.
• Helicopter performance classes decide where a helicopter may fly: Performance Class 1 is required for flights to or from sites in a congested hostile environment.
• Pilots must pass recurring proficiency checks; the UK text gives six consecutive months.
• Aircraft companies must carry minimum insurance under Regulation 785/2004, and a broker should be able to show you the cover.

Who regulates helicopter charter in the UK?

The Civil Aviation Authority (CAA) is the UK's aviation regulator, and it oversees the companies that operate charter helicopters. It approves each flying company, audits it, licenses the pilots and sets the standards for aircraft maintenance. Air operations rules in the UK come from the retained version of Regulation (EU) No 965/2012, often called the Air Operations Regulation, which is held in the CAA's regulatory library.

EASA stands for the European Union Aviation Safety Agency, which sets the equivalent rules in EU states. Following Brexit the UK and the EU keep separate systems that are similar in structure, which is why you will see references to both on charter documents.

If you want the plain-English version of the whole booking process, read how helicopter charter works in the UK. We write this guide as a charter company, not as a regulator, so for any legal question rely on the CAA's own pages.

What is an Air Operator's Certificate?

An Air Operator's Certificate (AOC) is the CAA's approval for a company to carry passengers or cargo for payment. Any UK company that wants to operate an aircraft for commercial air transport must first obtain an AOC and an operating licence from the CAA. The licence looks at the ownership and finances of the business, and the AOC covers operational safety, with an operations specification describing exactly what the company may do.

Most AOCs have no fixed end date, but the CAA keeps inspecting the holder, and it can vary or revoke the certificate if standards slip. The CAA publishes a list of UK AOC holders, aeroplane and helicopter, so anyone can check a UK company. A company based abroad must hold an AOC from its own country's authority.

This is what we mean when we say Charter-A Helicopter uses helicopters operated on a UK CAA or EASA approved AOC. It means the aircraft is flown by a company that holds that approval from the UK CAA or from an EASA member state's authority, not that Charter-A itself flies the helicopter. We arrange the charter; the approved company flies it.

What is the difference between commercial and non-commercial operations?

Commercial air transport (Part-CAT) is the rule set for flights that carry passengers for payment, and it requires an AOC. Non-commercial operations are flights where nobody is paid for the carriage, such as a company flying its own staff. The two sets of rules look alike on purpose, but the approval route is different.

The CAA says Part-NCC applies the same essential requirements as commercial air transport in a proportionate form. A helicopter counts as complex if it is certificated above 3,175 kg maximum take-off mass, for more than nine passenger seats, or for a minimum crew of two or more pilots. The detail is on the CAA's Part-NCC page, which also warns that failing to make the declaration may affect insurance.

The point for a passenger: if you are paying for a seat or a charter, the flight should be commercial, on an AOC holder's certificate.

What is performance class, and why does a twin matter?

Performance class is a rule on how a helicopter must be able to perform if an engine fails, and it decides where the helicopter may operate. Performance Class 1 means the helicopter can continue the flight or land safely within the area available after an engine failure. Class 2 and Class 3 allow less margin and carry more restrictions.

The CAA's Part-CAT text, rule CAT.POL.H.100, requires Class 1 for operations to or from aerodromes or sites in a congested hostile environment, and for any helicopter with more than 19 passenger seats. Helicopters with nine or fewer passenger seats can use Class 1, 2 or 3 in other situations. Read the rule in the CAA regulatory library.

That is why every aircraft we arrange is twin-engine: a single-engine helicopter is limited to simpler flights, and we do not offer single-engine charter. Our guide to choosing a helicopter shows how this affects the aircraft you are offered.

How are charter pilots trained and checked?

Charter pilots hold a CAA licence with a rating for the helicopter type, and the company flying them must keep checking them. We say "type-rated" for the licence rating that qualifies a pilot on a specific aircraft model such as the AW139 or H145 D3.

The company's checks are set in rule ORO.FC.230, which covers recurrent training and checking. The current UK text says a proficiency check run by the airline or charter company, a flight check done with the company, remains valid for six consecutive months. Pilots also complete separate licence proficiency checks, and companies run their own training programmes. The CAA text is in its regulatory library.

As a broker we do not train or check pilots ourselves. We choose approved companies, and we give you the facts on the aircraft and the flight in your quote. A broker or company that cannot say which AOC holder will fly you is a reason to ask more questions.

What insurance must a charter helicopter carry?

companies must carry minimum insurance for liability to passengers, baggage, cargo and third parties, set by Regulation (EC) No 785/2004 as it applies in the UK. The amounts depend on the number of passengers and the aircraft's maximum take-off mass. The consolidated text is on legislation.gov.uk.

Charter-A Helicopter works with companies that are fully insured. If you want to see the cover for a specific flight, ask us, because you are entitled to know what is in place. Your own travel or business insurance is separate, and you should check what it says about aviation.

What should I ask a broker or company before I book?

Ask who will fly you, what they hold and what happens if plans change. A good broker answers these quickly and in writing. Here is the list we would use if we were the customer:

1. Which company holds the Air Operator's Certificate for this flight, and is it on the CAA list or the list of an EASA member state?
2. What aircraft type will fly us, how many engines does it have and is it suited to this route?
3. Are the pilots type-rated and current on that aircraft?
4. What insurance is in place for passengers, and can I see the evidence?
5. What are the landing sites, and do they have permission and the right hours?
6. What is the weather policy? Ours is: if the flight is cancelled because of the weather, you pay nothing.
7. Is there a phone line I can use on the day? Ours is open 24 hours.

Charter-A Ltd is a member of the Air Charter Association, has traded since 2011 and is registered as company number 7668809. Its Trustpilot reviews are on Trustpilot. Those facts are not a guarantee, so please do ask the questions above of anyone you book with.

How do these rules show up in a real charter?

They show up in the choices behind the quote, not in a certificate you are shown on the day. For a business charter, we pick a twin-engine type from the fleet, check the landing sites in our directory of UK heliports and airfields and plan a back-up site.

For secure transport, a close-protection team will care about the same questions plus discretion and alternates. For events, the venue sets the rules: the corporate days out pages explain how landing slots work. For an airport link the airport transfer times guide covers permissions and hours. You can browse flights by area from our UK helicopter charter hub or start from Redhill, where our head office is.

Is helicopter charter safe compared with other transport?

Helicopter charter safety rests on regulation that manages risk rather than removing it, so we do not claim a flight is free of risk and we do not put a number on it. We have not found an official statistic that compares like with like, such as charter helicopter passenger journeys against road journeys, so we leave the comparison out rather than guess.

What you can do is judge the process: an approved company, a current pilot on the right aircraft, a sensible site, good planning and a pilot who is free to say no. For central London flights, Battersea Helicopter covers the same standards for the London Heliport.
