AgustaWestland (Pavilion OE1) is offering an increased-gross-weight version of its AW609 tiltrotor, which trades off some vertical takeoff capability for a higher payload limit. This will make it more attractive for some missions where vertical capabilities are not needed on departure.
Maximum Takeoff Weight
China’s CAAC certified the Avicopter AC311 light-single helicopter last Thursday. In announcing the approval, the Chinese helicopter manufacturer also released more performance numbers, including a 131-knot max cruise speed, four-hour maximum endurance and 335-nm maximum range.
The Avicopter AC311 light single-engine utility helicopter had its type certification “recommended” under China’s approval procedures last month. The Civil Aviation Administration of China’s (CAAC) type certification examination committee recommended issuance of the type certificate in a meeting held on May 4 in Beijing.
The European Aviation Safety Agency (EASA) granted type approval in late January to Franco-Russian engine maker PowerJet for a more powerful version of the SaM146 turbofan. Designated the SaM146 1S18, the engine offers 16,100 pounds of takeoff thrust, compared with the 1S17’s 15,400 pounds, thereby increasing the Sukhoi Superjet 100-95 LR’s mtow and extending its range to 2,470 nm with a full passenger load.
Bell Helicopter received Transport Canada approval today for a 500-pound increase for its Model 429, bringing the medium twin’s maximum takeoff weight to 7,500 pounds. The raised limit is an exemption to the Part 27 certification limit of 7,000 pounds and will enable the 429 to carry additional fuel reserves, increasing both range and loiter times, and enhance its IFR utility, the company said. According to Bell vice president Larry Roberts, this enhancement is especially useful for EMS and law-enforcement customers.
As the Eurocopter EC145 T2 light twin helicopter has completed “hot and high” testing, the manufacturer has released “promising” performance estimates.
Germany’s Ruag Aviation received EASA certification for the Do-228NG on August 18, two-and-a-half years after the company launched the program to bring the Do-228 back into production. The Oberfaffenhofen factory built more than 200 Dornier Do-228s before production ended in 2002. Ruag holds the original type certificate for the airplane and continued to provide aftermarket support for the 150 aircraft still operating.
This AIN pilot/reporter had an opportunity to fly the Eclipse on two different occasions, once on a short cross-country trip in March between Chicago and Nashville and again to Rockford, Ill., for some approaches, landings
and airwork. My instructor pilot was North American Jet Eclipse instructor Mike Vautell.
Cessna Citation 500, London, UK, March 8, 2008–A missing rivet head
Aircraft performance is a subject that many pilots dread, during both preflight planning and post-lunch ground school sessions in stuffy classrooms when the lines on flight manual charts blend together as eyelids droop and weary brains reject the stimulus of yet more caffeine.
