The Dassault Falcon 7X will be the first purpose-built business jet to have a fly-by-wire (FBW) system. Reduced crew workload, better aircraft performance and increased safety should be the major benefits, Dassault technical managers told AIN.

Dassault Falcon Jet describes its new 5,700-nm, $35+ million Falcon 7X three-engine business jet as providing 30 percent more range and 20 percent more cabin space at a 10 percent higher price than the 900EX. This positions the new airplane in the range and price market between its own 900EX, the Gulfstream IV-SP and the newly announced Global 5000 on one side and the GV and Global Express on the other.
Canada’s National Research Council has won a patent on “an active and adaptive rotor-blade control system called Smart Spring,” which is designed to reduce the noise and vibration when rotor blades interact with the vortices shed by the tip of the preceding blades. Previous engineering approaches, according to NRC, have attempted to alter the varying aerodynamic load on the blades to reduce the onset of this vibration.
CESSNA 425, SAN JOSE, CALIF., MARCH 6, 2002–“Just lost my needle…give me…” was the last transmission controllers heard from the pilot of a Corsair (Conquest I) climbing through 8,000 ft. Preliminary reports suggest the pilot experienced a loss of control in IMC that caused the Corsair’s in-flight breakup. Henry “Hank” Guenther, the 62-year-old instrument-rated pilot, and his two passengers died in the crash.
To support the 1,015 worldwide Falcon operators who fly an average 1.7 aircraft, logging 360 hours each year, Dassault has launched a renewed customer-support effort. The improved support network includes three technical centers that ensure 24/7 expert hotline service. Globally, 420 people– including 80 field service representatives– work in Falcon customer support facilities.
The first Falcon business jet with the EASy (enhanced avionics) flight deck from Honeywell took off February 21 from Bordeaux-Mérignac (France) Airport for its maiden flight. The EASy-equipped Dassault Falcon 900EX, S/N 97, is now in the development test phase.
Thales is to provide quadruple-redundant computers for the Gulfstream G650’s fly-by-wire (FBW) flight controls. The new large-cabin, ultra-long-range business jet will be the first to feature Thales’ Quad-Dual architecture. While Thales will act as Gulfstream’s deputy, the aircraft manufacturer retains authority for FBW system integration.
Autopilot maker S-Tec announced last month it has received FAA technical standard order (TSO) authorization for its IntelliFlight 1950 digital flight control system, incorporated as a standard feature in the SmartDeck cockpit from L-3 Communications Avionics Systems in Grand Rapids, Mich.
FAIRCHILD/SWEARINGEN SA-226-TC METROLINER, MONTREAL, QUEBEC, JUNE 18, 1998–Often layers of events come together to create catastrophes. Pilots may handle individual layers successfully, but combined those layers are often insurmountable. Nine passengers and two pilots died after the left wing of a Metroliner failed during an emergency landing at Mirabel/Montreal International Airport (CYMX).
Embraer revealed further details of its entrants into the midsize jet market, the seven- to 12-passenger midsize jet (MSJ) and mid-light jet (MLJ) at a press event in Washington, D.C. yesterday evening. The MSJ and MLJ share a common fuselage cross-section with six-foot stand-up headroom, Honeywell HTF7500-E turbofans, Rockwell Collins Pro Line Fusion avionics and Embraer’s first full closed-loop fly-by-wire flight control system.
