On December 1 Learjet 36 N26FN with two pilots and one passenger aboard lost its right elevator while maneuvering off the coast of San Diego. L-3 Communications Flight Capital was operating the airplane under Part 91. The NTSB said the local public-use flight departed North Island Naval Air Station, San Diego, about 9:30 a.m. VMC prevailed and no flight plan had been filed.
Conventional winglets have come to be widely used on airliners, whether in the form of the Airbus A320’s wingtip fence or the up-swept devices characteristic of the A330/340 and Boeing 747-400. And if winglets are good, shouldn’t bigger ones be even better? Wingmaker Airbus UK has been investigating their potential.
Winglets increase efficiency by reducing lift-induced drag. They do this by relocating and diminishing the vortex at the wing’s tip, resulting in lower fuel burn, higher cruise speed and longer range.
Supersonic business jet hopeful Aerion is still building a consortium to develop its airplane. In March the board of the Reno, Nevada-based company approved continued funding of the project through to program launch.
Research carried out in the field of supersonic transport within the European Commission’s 6th Research Framework Program (FP6) has come into the spotlight recently since Italy’s Alenia and Russian design bureau Sukhoi concluded a cooperation agreement.
Gulfstream Aerospace president Bryan Moss has dismissed the company’s long-discussed “Quiet Supersonic Jet” (QSJ). At a press conference at EBACE earlier this month, he asked, “Will Gulfstream build a supersonic business jet? Read my lips: No!” He said the company is devoting its research efforts in this field to two issues: rule changes that would allow supersonic flight over land and sonic-boom suppression.
The NTSB’s recently released final report implicates errors and FAR violations in the Nov. 30, 2004 fatal accident of a Hansa Jet moments after taking off. The crash killed both pilots, including the founder, owner and president of Toledo, Ohio-based charter operator Grand Aire Express. An FAA permit to ferry the twinjet from Spirit of St.
Canada’s National Research Council, NRC Aerospace (Hall 4 Stand C17a), is gathering detailed wake turbulence data with a specially equipped aircraft. NRC’s CT-133, a former military trainer, has just completed instrument test flights. Researchers are focusing on en route wake turbulence behind commercial aircraft, which seem to be more dangerous than expected.
Boeing is using Qinetiq’s low-speed wind tunnel for continuing evaluation of the 747-8, the latest iteration of the world’s first twin-deck widebody jetliner now midway through its fourth decade. The facility is located here at Farnborough, on the north side of the airfield.
An excerpt from the NTSB’s update on its investigation into the crash of the Cirrus SR20 that hit the 30th floor of an apartment building on October 11 while trying to make a U-turn over the East River (New York) provides insight into the role of the wind. “Radar data indicate that the airplane was flying over the east side of Roosevelt Island prior to initiating a 180-degree turn.
