Pratt & Whitney Canada took the first steps toward developing what would become the world's most popular turbine in 1956, when the company's engineering manager, Dick Guthrie, was told to hire a team of gas turbine engineers to lead the development of new generation of engines.

While most engine makers generally support a few hundred users of their products, Pratt & Whitney Canada (P&WC) supports the maintenance needs of a hugely diverse set of over 10,000 operators, 90% of whom have only one or two aircraft.

In the wake of June's Paris air show, both Airbus and Boeing issued victory statements detailing orders, options, commitments and letters of intent reportedly signed during the five-day event. Both rivals claimed they achieved or surpassed their most optimistic sales predictions, disseminating robust releases to the media. And, once more, the press corps—in most cases without the required restraint—agreed to the rules of the game, although that was largely meaningless.

It has been a 10-month-long wait, but operators should soon be returning their workhorse Eurocopter EC225s to the skies.

In the North Sea, the Eurocopter EC225 has been a workhorse, plying routes between bases in Norway and Scotland oil and gas platforms. But for 10 months, the helicopter has been missing from such operations, grounded as engineers searched for the root cause of the failure in its bevel gear vertical shaft. For the major operators in the North Sea region such as Bond Offshore Helicopters, Bristow Helicopters and CHC Scotia, the loss of the type from their fleets had a dramatic impact on their capacity to fly for customers.

Airlines are accusing some of the major airports in Australia and New Zealand of ratcheting up fees unfairly, and they are criticizing the governments of the two countries for not reining in these airports' pricing practices. Reflecting similar arguments around the world, local airlines say that fee hikes highlight the fact that regulators need to take a firmer line with airports. Now, the International Air Transport Association (IATA) has stepped up its own calls for the two governments to intervene more directly in airport disputes.
