Thierry Dubois is a freelance writer specializing in helicopters, business aviation and aerospace technology. He earned a degree in fluid dynamics from an engineering school in Toulouse, France in the mid-1990s. At an unexpected crossroads, he found his first job in journalism. In 1997, he started working for French aerospace weekly Air &amp; Cosmos in Paris. This lasted until 2000, when he moved south to Lyons. He then became a freelancer, working for various aerospace publications and has been part of the AIN team since late 2000. In addition to writing about business aviation, Thierry shares responsibility for the rotorcraft section. He also is a regular on-site writer for AIN’s daily editions at international airshows such as the Paris, Farnborough, Dubai and Singapore shows, as well as at EBACE in Geneva.
In 2007, he won the Honeywell award for “Best systems or technology submission” at the Aerospace journalist of the year awards. In 2013, he won an Aerospace Media Award for the "Best Safety, Training &amp; Simulation Submission."
In other activities, Thierry moderates international conferences on aviation technology topics. Thierry is married and has three children, who seem to begin enjoying the mountains–as their parents do.

Eurocopter has postponed its expectation for certification of the EC175 medium twin to this summer, citing longer-than-expected development of the Helionix avionics system. Deliveries will start in September instead of <a href="http://www.ainonline.com/aviation-news/aviation-international-news/2012-03-04/eurocopter-ec175-aims-late-2012-certification">“late in 2012,”</a> as initially planned.


The helicopter manufacturer declines to reveal the identity of the first customer, leaving room for speculation that offshore operator Bristow might not have confirmed its letter of intent yet.


<a href="http://www.ainonline.com/aviation-news/ainalerts/2012-01-17/eurocopter-improves-ec175-medium-twins-performance">Performance has been improved</a>, with Eurocopter now anticipating a cruise speed of 150 knots, 10 knots faster than the previous number, “without affecting payload-range” of the Pratt &amp; Whitney Canada-powered aircraft.


The EC175 is the first helicopter equipped with Helionix, to be certified under the latest international avionics standards (RTCA DO-297 and SAEARP 4754). “As a result of its trend-setting nature, the certification process for Helionix has been far more demanding and complex than that for previous legacy avionics systems,” a Eurocopter spokesperson said. The helicopter passed a detailed system-level design review in August. Meanwhile, the first production EC175 flew last week in Marignane, France.
