Fly-by-wire has become the norm for the larger and more expensive commercial and business aircraft and helicopters, but airframers continue to say the cost-benefit analysis for the lower end of the market has not been favorable to introduce this safety-enhancing and weight-reducing technology.

Swedish authorities have begun certification trials on two virtual control towers and a remote tower center in Sweden after the Saab-built system passed its acceptance tests in February. The r-TWR system, funded by Sweden's air navigation service provider, LFV, consists of one virtual tower and a remote tower center at the single-runway Sundsvall Airport on the east coast of the country, and a second virtual tower at the single-runway Ornskoldsvik Airport, 100 mi. to the northeast.

Solving a problem for NASA carries a cachet that ensures there is a strong response whenever the space agency posts a challenge to any of the online communities it uses to crowd-source new ideas.

More than two decades have passed since the last commercial helicopter was built in the U.K., but civil rotorcraft production could be on the verge of a comeback. While the last flirtations with the commercial sector—in the 1980s by what was then Westland were not especially successful—AgustaWestland, the helicopter manufacturing arm of Italy's Finmeccanica, believes it is time for its Yeovil-based U.K. subsidiary to reembrace the commercial world.

Over the years, France was—and remains, to some extent— an aerospace-proud nation. In the last several decades, it was often the vanguard for innovations. This forward-thinking momentum began more than 100 years ago when the great minds of the day gave a warm welcome to the Wright brothers after the two inventors failed to garner the support they needed in the U.S. In France, they were accorded respect, accolades and help in their efforts to make controlled flight a reality, including during their celebrated stay in Rheims, in 1909.

Russian aircraft manufacturer Sukhoi has started flight-testing the long-range version of its Superjet 100. But if the SSJ program is to become a success, the technical flaws that affect the baseline version must be conquered.

For the first time, a Boeing union has endorsed the company's plan to back away from guaranteed pensions but a minority group said it would rather strike instead, so the airplane maker has more uncertainty on its agenda.
