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.

Simplex Manufacturing has upgraded its powerline washing system, increasing the maximum water pressure to 2,000 psi. According to CEO Steven Daniels, the upgrade boosts endurance from five to 20 minutes with the same tank. Powerline washing takes dirt off insulator strings, thus regaining up to 5 percent of efficiency and, according to Daniels, with the system upgrade, “per day, you can wash three times more insulator strings,” he told AIN. The most visible piece is the 22-foot spray boom. The boom has a lateral swing of zero degrees to 100 degrees from the aircraft’s nose. The vertical movement is zero degrees to 45 degrees down. The system’s total dry weight is just under 700 pounds. 
Water pressure can be set between 500 and 2,000 psi. The tank’s capacity is 120 U.S. gallons. Stevens said the types best suited to installation of the system are the Bell 407 and the AS 350B3 Ecureuil.
