Bombardier considers fly-by-wire system for BRJ-X

June 15th, 1999

Bombardier Aerospace is developing state of the art 'fly-by-wire' technology for potential use in future Bombardier Aerospace Aircraft. The fly-by-wire system is being studied on a specially adapted flight test demonstrator aircraft as part of intensive investigations into its application at Bombardier facilities in Montreal.

"This study further demonstrates our commitment to developing new technologies for the ultimate benefit of our customers," said John Holding, executive vice president, engineering and product development at Bombardier Aerospace at the Paris Air Show.

While common on new large commercial aircraft, fly-by-wire's suitability and overall economic benefit to the smaller regional aircraft market needs to be fully evaluated in conjunction with our potential customers, said Mr. Holding.

Fly-by-wire control systems offer real benefits over conventional flight control systems. With a conventional system, the pilot moves the aircraft through either mechanical or hydro-mechanical linkages from the cockpit to the control surfaces. Fly-by-wire, in contrast, features electrical/electronic inputs from the cockpit to the control surfaces enabling the pilots' commands to be augmented by additional inputs from flight control computers. This provides for a more responsive and precise control of the aircraft, which allows a more efficient aerodynamic design resulting in reduced drag, improved fuel burn and reduced weight and pilot workload.

Bombardier say the first potential application for this technology could be the BRJ-X(a) product line which was announced at the Farnborough International Air Show last September. A BRJ-X Airline Advisory Council was convened in Montreal during the winter as part of the market evaluation of the five-abreast aircraft, which would be the largest offering in Bombardier's stable of commercial regional aircraft.

The consultation process could lead to a decision to proceed with the new aircraft next year. Type certification and delivery would be in late 2003.
