The Bombardier Learjet 75 light jet–a longer-range version of the Learjet 45 with Garmin G5000 integrated avionics, winglets and more efficient Honeywell TFE731-40BR engines–received FAA certification on Thursday. Deliveries have already begun for U.S. and Canadian customers, a Bombardier Aerospace spokeswoman told AIN. Certification and delivery efforts are pending for its smaller sibling, the Learjet 70.

Aviation Partners Boeing last month announced that, after launching on the Boeing 737 NG, split scimitar winglets can now be fitted on the Boeing BBJ family. The new split scimitar winglets offer a significant reduction of drag compared to the non-winglet-equipped Boeings and a noticeable drag reduction for those equipped with Aviation Partners Boeing blended winglets.
Boeing said it has completed aerodynamics, engine and weight audits that together have given it a clearer picture of the future operating performance of the new 737 Max. The manufacturer now says the re-engined narrowbody will burn 14 percent less fuel than today’s 737-800NG, one percent better than it previously estimated.
Two faculty members from Penn State’s vertical-lift research center of excellence were honored recently at the fourth annual International Basic Research Conference on Rotorcraft Technology in Tianjin, China. Professor Edward Smith and research associate Jianhua Zhang were honored for their paper, “Influence of Aeroelasticity Tailored Wing Extensions and Winglets on Whirl Flutter Stability.” The research was underwritten by the National Rotorcraft Technology Center and the NASA Ames Research Center.
It still seems unusual to climb into the cockpit of a sophisticated modern jet like Bombardier’s rejuvenated Learjet 75 and find a Garmin suite instead of a panel full of Honeywell or Rockwell Collins avionics. It isn’t hard to figure out; there are no flight management system control display units in the Learjet 75’s pedestal. Indeed, it seems that the concept of the standalone FMS has been banished from the jet’s Bombardier Vision (Garmin G5000) flight deck.
Boeing has increased its estimate of the operating performance of the 737 Max, saying the re-engined narrowbody will burn 14 percent less fuel than the current 737NG consumes. In July, the manufacturer said the 737 Max with new CFM Leap-1B turbofans will be 13 percent more fuel efficient.
Aviation Partners (Booth No. C8114), in cooperation with Boeing, is launching its new Split Scimitar Winglet program for Boing BBJs. Split Scimitar Winglets are already available for 737 NGs.
The Split Scimitar Winglet modifies the existing blended winglet on the BBJ by adding a Scimitar-tipped ventral strake, reinforced internal winglet structure and replacement of the aluminum winglet tip caps with more aerodynamically shaped Scimitar tip caps.
Tamarack Aerospace and Cessna Aircraft signed an agreement this week at NBAA 2013 under which Cessna will market, sell and install Tamarack’s active winglets for the CitationJet family through the CJ3. The winglets provide more range, increased useful loads and improved high-and-hot performance, while simultaneously improving fuel economy.
Winglet Technology of Wichita, Kan. (Booth No. C12043), the company that supplies its Elliptical Winglets for the Citation X, is collaborating with the Cessna service center network to offer the winglets for retrofit on the Citation Sovereign. Flight testing is expected to begin this month and the companies are targeting entry-into-service in the first quarter of 2015.
