On Monday, the new 3,400-pound-thrust Williams FJ44-4A FADEC engine slated for the Cessna Citation CJ4 flew for the first time aboard a Citation testbed. “The first flight of the new engine went very well, and performance exceeded our expectations during the 50-minute flight,” said CJ4 Program Manager Norm Baker III. According to the Wichita aircraft manufacturer, the coming "moderately swept" wing Citation CJ4will have a full fuel payload of 1,000 pounds, a maximum payload of 2,1000 pounds and a 435-knot cruise spawned from any runway longer than 3,299 feet. The jet is scheduled for first flight in the first half of 2008, with entry into service following in 2010. The FJ44-4A outshines the CJ3's FJ44-3A thrust output by 580 pounds and "has the best thrust-to-weight ratio in its thrust class," Cessna notes. It also incorporates proprietary aerodynamic improvements that result in "a significant reduction in fuel consumption." Like the CJ1, CJ2 and CJ3, the CJ4 will come standard with Rockwell Collins Pro Line 21 avionics featuring four 8- by 10-inch LCD screens. Other standard equipment includes engine indication and crew alerting system (EICAS), TAWS Class A (terrain awareness warning system), TCAS II (traffic alert and collision avoidance system), cockpit voice recorder (CVR), electronic charts and XM graphical weather, according to Cessna.
