How to Buy a Private Helicopter: 5 Things You Need to Know When You Are Buying a Private Helicopter

There are many benefits of owning a helicopter, including getting to work on time when living 100 miles (ca. 161 km) away from your office. The main advantage of owning a helicopter is freedom. Once you have permission and some space, you can set your course for any destination.

A private owner in the United Kingdom can fly to Devon and back to London without stopping to refuel. A pub in Oxford, the Manson’s Arms, has a helipad. The photographs of helicopters that visit adorn the walls of the pub. It is a thrilling and bizarre place to visit.

Modern helicopters have engines that are quieter and more efficient with advanced glass cockpits that offer fewer distractions for pilots. Airbus Helicopters’ Ed Sale responded to GQ at the Elite London event giving insight into what to consider when buying a private helicopter.

1. Will You Be the Pilot or the Passenger?

The majority of helicopter owners are pilots so they can fly themselves. Private pilots and those who own a helicopter and fly themselves prefer hands-on, less bulky designs.

Bigger helicopters are usually reserved for professional pilots while the owners sit in the back. The big shots use this as their executive means of transport. Midrange helicopters have administrative abilities too but are fun to handle.

The bigger the aircraft, the more experience a pilot requires. A well-trained amateur can fly any of the Robinson chopper models. The same applies to the B3 and B4 Eurocopter Ecureuil, AgustaWestland Koala and Bell 407. If you are looking at bigger models, like the AgustaWestland A109 with more sophisticated instrumentation, you will need a professional pilot.

If planning to become a pilot, next choose a flying school. Lots of flying schools will issue Private Pilot Licenses PPLs(H). Ask friends with helicopters to recommend a good flying school.

It helps if the flying school is local to you as you need a minimum of 45 hours of training over 12 months. Training costs vary from school to school but expect it to cost around $26,200 (around £20,000). This covers your tests, exams, flying hours, medicals, equipment, and airfield fees.

Training at Heli Air, one of the UK’s largest Robinson helicopter distributors, will cost you $10,500 (around £8,000). This covers theory in subjects like meteorology, air law, and flight planning. A Class 2 medical is compulsory.

After qualifying, you need an annual review to renew your license. You can opt to expand your qualification to include formation flying and night flying. The choice is yours.

2. Predetermine Your Budget

Design, capacity, and the manufacturer determines a helicopter’s price. Set your budget right from the start. It helps narrow your search.

Just like cars, you will have a range of options. Sloane Helicopters marketing director, Giorgio Bendoni, says first-time buyers can choose from the two-seater, single-piston Robinson R22 to the twin-turbine, eight-seater AgustaWestland Grand. It depends on budget flexibility.

While helicopters are expensive, some are cheaper than a Lamborghini. The Robinson R44, the world’s most famous helicopter, costs only $350,000 (around £313,500) and half that second-hand.

When setting your budget, add maintenance costs too. Some helicopter’s cost more to maintain than others. Lower priced helicopters can cost more in maintenance over the long run.

The AgustaWestland Grand and the AgustaWestland A109 are great in sophistication and space, but with an annual depreciation of five to 10 percent, you may want to weigh your options.

You should also consider the cost of insurance, capital investment, and depreciation.

3. How Far Will You Travel?

Aircraft manufacturers offer similar models with a small tweak in design and performance. Cheaper helicopters are smaller. And this limits the number of people it can carry, fuel capacity, and distance it can travel.

So, you need to decide how many people need to travel in your helicopter regularly. Also look at the distance it can travel before needing to refuel. The H125 is a midrange helicopter that guarantees 300 to 350 miles (ca. 563 km) or 2½ hours without refueling.

4. Other Considerations

The Airbus H160 is a new sleek design marketed to business and private customers, while the H125 has strong competition from the Bell 407. The cabin is separate from the cockpit and is luxurious. It has two seats facing each other and is a great option if you have a pilot. In contrast, an Airbus is a better option with you as the pilot as there is no separation from your passengers.

The choice of interior should reflect the helicopter’s purpose. Some people ignore carpets as it is a lot of work to keep clean. Leather seats are an attractive option as are seats with twin leather stitching which are currently in vogue.

Landing Space is Limited

Landing spaces in London are limited due to their tight restrictions on noise control, which limits helicopter paths. Battersea Heliport is the best place to land and continue your journey using other means. Places you can land outside London include Elstree, Denham, Biggin Hill, and Northolt.

Grab a helicopter landing guide to find somewhere to land in London. It has a list of landing sites around the UK and their phone numbers. This allows you to request landing permission before leaving for your destination. They may let you land for free or for a small fee (around $50).

Terms You Should Know

There are terms you should know if you intend to own a helicopter:

  • VFR (Visual Flying Rules) means you have to keep sight of the ground.
  • IFR (Instrument Flight Rules) means you can fly above or in the clouds.
  • A two-seat piston engine VFR is a basic helicopter.
  • ILS (Instrument Landing System) is what you dial into to get to the ground.
  • You use a noise-canceling headset for communication.
  • Autopilot allows you to control the aircraft without moving the controls and is not available in all helicopters.
