Cessna has successfully completed certification flight tests of Safe Flight Instrument’s automatic throttle system for the Citation X. FAA STC approval of the autothrottle system for the Mach 0.92 jet is expected within the next month, according to Safe Flight. By controlling speed and thrust, the Cessna Citation X autothrottles will result in increased situational awareness, reduced crew workload, greater passenger comfort and extended range/payload potential, Safe Flight said.
Cessna Citation X
A Cessna Citation X equipped with Winglet Technology (Booth No. 1743) elliptical winglets set an unofficial speed record October 28 by flying 3,479 nm nonstop from Anchorage to Miami in seven hours and 13 minutes at an average speed of 482 knots. Details of the flight have been submitted to the National Aeronautic Association for review and certification for jet aircraft in the Class.I.I.(35,274 to 44,092 pounds mtow) category. The aircraft was flown by Al Larson and Chuck Feaga.
Crane Aerospace & Electronics has received a number of new product approvals and selections on a variety of business jets. Crane’s FAA-approved SmartStem wireless tire pressure monitoring system now allows Part 135 pilots to check tire pressures on all certified aircraft. “There are presently no other products on the market that allow a Part 135 pilot to check his own tires,” the company noted.
The transonic speed spat between Cessna’s Citation Ten and Gulfstream’s G650 is likely to hit of the stops at Mach 0.95 when it encounters not “the sound barrier” but required safety margins. With the Ten’s top speed now pegged at Mach 0.935, Gulfstream’s G650 could thus leapfrog the Ten only slightly, if the Savannah-based aircraft manufacturer even chooses to do so.
On Friday, Cessna announced that it has raised the top speed for its Citation Ten to Mach 0.935, which would make it the fastest civil aircraft in service once certified. This eclipses the speed of its Citation X predecessor by Mach 0.015 and the currently stated top speed of the soon-to-be-certified Gulfstream G650 by Mach 0.010.
Cessna Aircraft announced today at LABACE that it has again increased the range–to 2,500 nm–of its in-development, midsize Citation Latitude. When announced at the NBAA Convention last year, the Latitude was originally expected to have a range of 2,000 nm. In February, Cessna stretched the airplane’s legs to 2,300 nm, and after further discussions with customers it decided to extend the range again, to 2,500 nm.
L-3 Avionics Systems announced today that the FAA has granted TSO approval for its GH-3900 electronic standby instrument system. Several business aircraft OEMs have selected the GH-3900 as standard equipment, including Bombardier for the Learjet 70/75 and Cessna for the Citation Ten. Additionally, Rockwell Collins has selected the GH-3900 ESIS for its Pro Line Fusion Flight Deck. The primary flight display backup instrument is capable of meeting airworthiness requirements for almost any fixed- or rotary-wing transport-category aircraft, says L-3.
Cleveland Hopkins International Airport-based Constant Aviation has completed its fifth winglet modification on the Citation X. According to the company, adding the winglet option allows the aircraft to climb directly to 34,000 feet in 29 minutes, compared with a 93-minute step climb without the winglets, increasing range by 160 nm. It also allows the Citation X to depart from high/hot airports with 1,200 pounds more payload or depart with the pre-winglets payload and fly 400 nm farther, according to Stephen Maiden, the MRO facility’s president.
The FAA proposes an airworthiness directive for the Cessna 750 Citation X prompted by reports of direct current (DC) generator overvoltage events. The generator control unit (GCU) overvoltage protection circuit can become damaged and allow high voltage to pass through to the airplane systems and electrical components, which, if not corrected, could result in smoke in the cockpit and loss of avionics and electrical systems.
Six months after launching its midsize Citation Latitude, Cessna (Stand 7081) announced at EBACE this morning that it will offer a $25.9 million (2012 dollars) stretched version–the “Longitude–that can fly 4,000 nm at Mach 0.82.
