Thales (Booth No. 789) has been selected by Bombardier to provide a fly-by-wire spoiler system for the Canadian OEM’s new Learjet 85. The Thales spoiler package consists of one digital flight control computer and an integrated spoiler control level and actuation system. Thales used its latest dual flight control computer architecture contained with robust packaging designed specifically for composite aircraft environmental conditions.
Aircraft flight control systems
As more business jet buyers worry about the damage their airplanes are potentially causing the environment, French business jet maker Dassault is seeking ways to make future Falcons greener.
At last year’s NBAA Convention, Embraer tested the water, so to speak, for two new aircraft it described as a midsize jet and a “mid-light” jet and began accepting “letters of interest,” along with $90,000 and $70,000 refundable deposits, respectively. But it stopped short of an official program launch.
Cessna has selected Parker Aerospace to supply the flight control system for its large-cabin Model 850 Citation Columbus. The contract is estimated at $400 million over the life of the program.
To see where business jet maintenance is headed, just look at mechanics’ toolboxes. Those who turn wrenches on the most modern airplanes still need the standard-issue screwdrivers, wrenches, sockets and ratchets, but they also need a powerful computer to analyze what ails their charges.
An integration fault in the Bombardier CRJ1000’s fly-by-wire rudder control system has forced the company to install a software revision in the prototype destined to make the type’s first flight, resulting in delays to ground testing and contributing to the postponement of first flight.
An integration fault in the Bombardier CRJ1000’s fly-by-wire rudder control system has forced the company to install a software revision in the flying prototype, caused delays to ground testing and contributed to the postponement of first flight until probably early next month. “When you put brand new hardware together like this there’s always a few surprises here and there,” CRJ program director Jean-Guy Blondin told AIN yesterday.
Honeywell is testing a new type of automated cockpit concept that can take control of airplanes to keep them from flying into the ground or buildings. Called assisted recovery, the system uses the enhanced ground proximity warning system (EGPWS) and autopilot to steer an airplane away from terrain or obstacles if the pilot has not attempted to do so within five seconds of an EGPWS warning.
The very light jet segment got a bit more crowded early last month when Westport, Conn.-based startup Avocet Aircraft and Israel Aircraft Industries publicly announced a partnership to develop a six- to eight-seat (including pilot) twinjet.
Dassault has bucked the trend among business jet manufacturers of announcing massive job cuts, furloughs or temporary factory closures since the beginning of the economic downturn in 2001. Still, the French company has significantly reduced production rates for its Falcon line.
