Aviation Partners said 30 hr of initial flight testing of its winglets installed on a Hawker 800 (designated the 800SP) has verified a 7-percent reduction in cruise fuel consumption, netting an increase of 150 to 200 nm in range, “significant” improvement in takeoff second segment climb, better payload capability from hot-and-high airports and optimum cruise altitudes of about 2,000 ft higher.
Reno, Nev.-based Aerion on Sunday announced at the Dubai Air Show that it is now accepting letters of intent for a “limited number” of early delivery positions for its 12-seat supersonic business jet (SSBJ). “Market demand has driven our decision to begin accepting deposits,” said company vice chairman Brian Barents.
Bombardier has selected Dubai as the venue for the airshow introduction of the Learjet NXT, an all-new business jet intended to fill the market gap between the company’s $13.3 million Learjet 60XR and $21 million Challenger 300.

Business aircraft cabin specialist Infusion Design has long preferred a low profile. Now celebrating its 10th anniversary, the Kansas City-based firm is happily stepping out of the shadow of anonymity, most recently with designs for Spectrum’s Freedom S-40 and Adam Aircraft’s A700 mockups, as well as concept designs for Aerion’s supersonic business jet proposal.
The business aviation industry is on a constant quest to create a more comfortable cabin environment for the traveler, but only in the past several years have aircraft manufacturers tackled the nagging issue of cabin altitude and its physiological effects, and with some success.
“Welcome to Lear Jet Country,” a marketing slogan that attached itself to the early-20-series Lear Jet, is likely to be remembered only by industry old-timers who recall the airplane’s ability to take off and climb to 41,000 feet without effort. It is a capability that disappeared with the advent of the Learjet 35/36.
The FAA’s rules are a “barrier to the development and application of supersonic technologies in advanced general aviation aircraft,” said the General Aviation Manufacturers Association in comments submitted to an agency request for information on SST noise rules.
Operators of U.S.-registered CitationJets must disengage the pitch-trim/ autopilot circuit breakers to prevent runaway pitch trim, a condition that has led to at least one accident, according to an October 21 AD (2203-21-17). A CitationJet was ditched on July 22 in Penn Cove in Coupeville, Wash., following a loss of elevator trim control, resulting in an uncommanded nose-down pitch attitude.
The first test flights of a Cessna Citation X equipped with Winglet Technology’s new elliptical winglets are proceeding well, according to Bob Kiser, president of the Wichita-based modification kit manufacturer. The winglets are expected to give the airplane an even higher maximum cruise speed at high altitude as well as improved climb performance and longer range.
