NASA and Gulfstream last month wrapped up six weeks of flight testing at the Dryden Flight Research Center at Edwards AFB in California aimed at proving whether pilots can use high-definition video cameras and LCD monitors to take off and land a supersonic business jet (SSBJ) in lieu of natural forward vision.
The New Nose Company’s twin-turboprop ClipperSpirit amphibian was announced in early October, coincidentally at about the same time Dornier relaunched the certified Seastar amphibian program. The ClipperSpirit at present is a design looking for a financial partner.
Would-be manufacturers of supersonic business jets–Aerion, Gulfstream and Supersonic Aerospace International–are encouraged by an updated FAA policy statement that aligns noise limits for future civil supersonic aircraft with current Stage 4 noise regulations. According to the FAA, this action is intended to provide guidance on noise limits for supersonic jets.
Aerion, the U.S. company that is developing a supersonic business jet (SSBJ), has welcomed an FAA policy shift which it believes “seems to crack open the door for supersonic cruise speeds” if, in the words of FAA policy guidance released last month, “the noise impacts of supersonic flight are shown to be acceptable.”
Diamond D-Jet S/N 003 made its first flight on October 5 with the upgraded Williams International FJ33-5A engine. S/N 003 is now in the final configuration for certification, with the new engine, new engine inlets and fairings, aerodynamic changes and production winglets. The new engine will be derated to match the power output of the previous FJ33-15, but Diamond plans to offer a higher-thrust D-Jet later in the program.
Hopeful manufacturers of supersonic business jets–Aerion, Gulfstream and Supersonic Aerospace International–are encouraged by an updated FAA policy statement issued last week to align noise limits for future civil supersonic aircraft with current Stage 4 noise regulations.

Winglet Technology reports “significant progress” toward FAA certification of its Cessna Citation X elliptical winglet modification. Announced at NBAA’07 in Atlanta, the program has moved through full-scale wing static test to installation of the modification kit and production winglets on Cessna’s test aircraft.
The Defense Advanced Research Projects Agency (Darpa) is giving Boeing $9 million over the next two years to investigate the feasibility of developing a disc-rotor compound helicopter capable of achieving forward speeds of up to 400 ktas while retaining all the maneuverability of a traditional helicopter. The disc-rotor would have a rotating circular wing with retractable blades that extend from the disc edge for takeoff and landing.
High fuel prices are giving operators new motivation to add aftermarket winglets to airplanes without them. Here at NBAA’08, King Air 90 owners have one last opportunity to place pre-certification orders for Winglet Systems from BLR Aerospace (Booth No. 4066), according to Dave Marone, BLR vice president of sales and marketing. Certification is “imminent,” he said.
