A wet Tuesday in February at an airfield on the north Norfolk coast. One of the two helicopters is out over the sea doing a crew change at a wind farm. The other is on the apron with its cowlings open and an engineer underneath it, and it will not move for nine days.
The machine on the apron is not broken. It has flown nine hundred hours since it last came out of the workshop, and at a number set by the manufacturer it goes back in whether anything is wrong with it or not. Nobody sends an invoice for that in advance. It has been accruing quietly, at so much per hour, since the day the counter was reset.
That is the whole trade. Every hour you sell moves an expensive machine closer to a bill that arrives years later in one piece.
The maintenance clock runs whether the machine earns or not
A charter operator's product is a flying hour. The price of that hour has to carry the fuel, the pilot, the insurance, the hangar, the landing fees and the engineering, and then it has to carry the part of the next overhaul that this particular hour has used up.
That last item is the one that catches people. Major components on a helicopter have lives measured in hours or in cycles rather than in years. The engine, the gearbox, the rotor head and a long list of smaller parts each carry a number, and when the number is reached the part comes off and goes away to be overhauled or replaced, whatever the state of your order book. An operator who prices only the fuel and the pilot is selling hours at a loss and will not find out for three years.
The discipline is to treat the reserve as a real cost taken at the moment of flight. Set a figure aside per hour, put it where it cannot be spent, and price the charter above it. Roughly half of what a well run operator bills survives the direct cost of flying it, and the office, the hangar and the owner all come out of that half.
What the customer actually buys is availability
Very little of this work is somebody ringing up for a lift. About four fifths of it is business to business and most of it is contracted: crew changes to an offshore wind farm, an air ambulance flying for a charity, aerial survey and powerline inspection, pipeline patrol, corporate and race day work, film and broadcast.
The good contracts pay for readiness. A customer who needs a machine on a morning nobody can predict is buying the right to have one, and pays whether it flies or not. That clause is the difference between a business that survives a week of fog and one that does not, because weather stops this work outright and short winter days stop it earlier still. Days lost to a low cloud base cannot be sold again in March.
Readiness has a price. It means a second airframe, or an arrangement to bring one in quickly, and it means pilots on the payroll in the months when there is nothing much to fly. A commercial helicopter pilot is a £78,000 salary, and there is a firm limit to how many hours any one of them can fly in a month.
The entry cost reflects all of it. Getting in properly runs from about £1,500,000 to £9,000,000 once you have the machines, the hangar, the tooling and a float of spares. Britain has perhaps sixty operators of any size doing this work, employing a few thousand people between them. None of that is read off a published table; it is the size of the thing rather than a census of it.
The Civil Aviation Authority holds the whole thing open
Commercial flying for hire and reward runs on an air operator certificate issued by the UK Civil Aviation Authority. The certificate lists what you are permitted to do: the aircraft types, the kinds of operation, the conditions. A separate operating licence covers you as a commercial air carrier. Alongside both sits continuing airworthiness: the approved arrangements and the records that prove every component on every airframe is inside its life.
The CAA's powers here are not subtle. It can suspend or vary the certificate, it can restrict the operations listed on it, and a type can be grounded on an airworthiness directive. A directive is a safety instruction against an aircraft type or a component, and it takes no interest in whose fleet it lands on. If you operate three of one type and the directive covers that type, you have three machines and no service on the same morning.
The ten-seat line decides the VAT
Passenger transport in Britain is zero rated for VAT, which is why a rail ticket and a ferry crossing arrive without it. The relief depends on the vehicle being designed or adapted to carry ten or more passengers.
Most helicopters are not. A machine with six seats is standard rated, so a charter carries VAT at the standard rate on the whole of it.
For offshore and survey customers that hardly matters, because they are registered and reclaim what you charge. For private and leisure work it is tax on the invoice that a ferry or a scheduled airline doing comparable mileage never has to add.
It ends with a notice, not a price war
Most small businesses fail slowly. This one has a specific and repeatable way of going.
A directive lands on your type and the fleet stops. The contract you were pleased with now works against you, because the availability you were paid for is an obligation you cannot meet. You wet lease a replacement from somebody who knows exactly how badly you need it, and you run the contract at a loss to keep it. Then the overhaul that was three months away arrives while the machine is already down, and you are paying for an airframe that has not earned since the spring.
That is what makes it unlike an ordinary small business. An airline lives on filling seats and dies in a fare war. A charter operator lives one airframe at a time, against a clock that runs whether anybody is paying or not, and its worst morning begins with a piece of paper from a regulator.
Where this shows up in the game
Helicopter Charter is one of the specialist trades in Business Baron. It is one of the specialist trades, and it wants the full game underneath it.
The monthly decision is which airframe goes on which contract, knowing that the machine you commit is the one you cannot offer to the next caller. The number you watch is flying hours per airframe per month set against the maintenance reserve owed per hour, and it is entirely possible to have a busy month and finish it worse off than you started. Winter takes days off you, contracts with availability clauses pay you through them, and the two rarely line up neatly.
The Civil Aviation Authority turns up as an inspection and, now and then, as a directive against a type you happen to operate. When that lands the fleet stops earning, the reserve carries on accruing, and you discover whether you kept a spare airframe or a good relationship with somebody who has one. The Helicopter Charter page sets out the startup range, the margins and the approvals the trade runs on.
