The Australian Transport Safety Bureau (ATSB) has released a research report examining every incident of stall warning activation between 2008 and 2012 in transport-category aircraft operating in Australian airspace. The incidents recorded in the October 31 report include both local aircraft as well as those of foreign registry.
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.
Among the operational topics for the technical committee at the triennial ICAO Assembly were significant safety issues. One paper from the Russian delegation provided a description of extensive studies of wake vortices, and the development of a wake vortex safety system that would use outputs from ADS-B, Swim and two Aviation System Block Upgrades 1 elements, with pilot alerts transmitted over the anticipated datalinks in that period–that is, by 2018.
For many pilots, the first exposure to the benefits of an angle-of-attack (AOA) indicating system comes during their first simulator session toward a business jet or airliner type rating. Because fewer pilots are entering the world of professional flying via the military–which actively uses AOA systems–and general aviation training airplanes are rarely AOA equipped, new civilian pilots get little exposure to AOA indicators and their safety benefits.
Aviation Performance Solutions (APS) released version one of its new iPad app based on the original airplane upset and recovery training aid. The app is designed to make studying the issues surrounding loss of control in flight as convenient as possible. The app includes eight separate modules covering the basics of upset prevention and recovery training, aerodynamics, causes of upsets and recovery techniques.
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.
BLR Aerospace (Booth No. C7034), announced here at NBAA that it expects supplemental type certificate (STC) approval soon for a King Air 90 Ultimate Performance Package, which will allow operators to realize the full potential benefits that BLR’s winglets can offer in operating efficiency. Approval was delayed by the U.S. government shutdown and furlough of non-essential FAA employees.
The firm started in 1999 as the HVLS Fan Co., an acronym for high-volume low-speed fans. That name accurately described the design and efficiency of the company’s products, but after three years in business, according to the Lexington, Ky.-based manufacturer, “we finally had to bow to the sentiments of our customers and concede that we do, in fact, design and manufacture some Big Ass Fans.” Hence, the current brand name.
