Effective yesterday, an EASA Airworthiness Directive (AD) has restored the full original flight envelope for the Dassault Falcon 7X, providing the fly-by-wire control system is updated. Dassault has developed a modification of the system to improve “the monitoring and reversion logic of the horizontal stabilizer trim system,” EASA said.

Richard Bach, the well-known pilot and author of numerous books, articles and short stories about aviation (he’s probably most widely known for his book Jonathan Livingston Seagull), once wrote a story about a mythical flight school somewhere in the western U.S. and far away from civilization.

Practically all Falcon 7Xs are flying again, following the EASA’s re-authorizing flights for the entire fleet on July 7, three weeks after giving the majority of the fleet the green light to return to service. The FAA followed suit and released an equivalent alternative method of compliance (Amoc) on July 8. As of July 19, only three 7Xs were still on the ground, for reasons unrelated to the pitch trim issue, according to Dassault.

A fix has been designed and certified for the runaway elevator trim control that was experienced by a Falcon 7X in late May. Dassault chairman and CEO Charles Edelstenne said the aircraft was grounded by EASA at Dassault’s behest. “We immediately mobilized all the resources at our disposal to identify the cause of this malfunction and develop a solution,” he said.

Airbus has already started to produce the first elements of the “sharklet” wingtips for incorporation on wings for standard A320 aircraft that are expected to enter service in about 18 months’ time, during the fourth quarter of 2012. It also has begun to convert the original A320 (MSN 0001), including installation of flight-test instruments, to act as a test bed.

Jim Irwin has launched a new company that is targeting the light helicopter autopilot market. Irwin is a veteran of helicopter and fixed-wing autopilot development and he sees an opportunity that hasn’t been fully tapped.

Cool City Avionics wants to create a light helicopter autopilot market.

Named after the Texas city near Mineral Wells where it is located, Cool City Avionics (Booth No. 4753) is taking a modular approach to certifying light helicopter stability augmentation and autopilot systems. The goal is to maintain component commonality and use proven automatic flight control design concepts while employing current technology.

The innate intelligence of fly-by-wire (FBW) flight controls makes them a natural for reducing the relatively high pilot workload that can come with rotary wings.
