An international field research campaign led by Airbus and NASA has gathered a wealth of data on icing conditions in convective weather, especially on ice crystals that cause engine icing. The eight-week effort ended in March in Darwin, Australia, and the researchers expect to publish their report early next year. The partners in the project hope to gain a better understanding of icing conditions that will allow them to devise mathematical models for equipment manufacturers to use when designing detection systems.

Safe Flight Instrument introduced its new Icing Conditions Detector (ICD) today at EBACE. The patented optical ICD provides an alert that icing conditions exist before ice can accrete on the aircraft. Composed of a single line-replaceable unit, the system is intended for operation in all modes of flight, according to Safe Flight. The system, currently under evaluation in a variety of airframe types, provides an instantaneous warning when icing conditions are present before ice accretion has an opportunity to reduce aircraft performance and controllability.

Dallas Addison Airport (ADS) recently became part of a five-year, $10 million radar network demonstration project to learn how X-band sensors can improve hazardous weather forecasts, warnings and responses in dense urban environments.

Scientists in the propulsion system laboratory (PSL) at NASA’s Glenn research center in Cleveland, Ohio, have developed a test facility that can recreate high-altitude engine icing, a long-awaited capability that should equip the aviation industry to tackle a poorly understood hazard.

Over the last 20 years, the aviation industry has documented more than 200 incidents in which turbofans have lost power during high-altitude flights, according to NASA.

Rockwell Collins (Booth No. 8040) opened Heli-Expo 2014 with announcements that its new MFD-268P2B multifunction displays are now standard equipment on Sikorsky S-92 medium-lift helicopters.

Available on new S-92s delivered this year, the MFD-268P2B offers improved color stability and readability for high-angle, cross-cockpit viewing. The displays may also be upgraded, with provisions for installation of synthetic vision, H-TAWS terrain awareness and the company’s MultiScan weather radar systems.

Safe Flight digital powerline detection system

Safe Flight (Booth No. 2516) introduced its upgraded digital powerline detection system (DPDS) and provided an update about ongoing development of its icing conditions detector (ICD) at Heli-Expo 2014.

The DPDS adds a digital signal processor to Safe Flight’s previous analog system, allowing the detection of both 60Hz and 50Hz frequencies produced by power lines around the world. Safe Flight director of government and military sales Greg Hilewitz noted testing on an AS355 showed the DPDS detected a 22,000-volt line at more than one statute mile distant.

Brazil’s Agência Nacional de Aviação Civil (ANAC) has approved CenTex Aerospace’s Halo 250 conversion for the Beechcraft King Air 200 series. It allows any King Air 200 to carry up to 920 pounds more payload by increasing the maximum takeoff weight to 13,420 pounds from 12,500 pounds. A new Airplane Flight Manual supplement has performance data for takeoff flight path to 1,500 feet agl and the landing approach flight path in normal and icing conditions.

A Fokker F100 charter flight in Western Australia experienced a hard landing on Oct. 12, 2012 after encountering a dry microburst-induced wind shear. No one was injured; however, the aircraft was substantially damaged, including wrinkled skin in the forward and rear portions of the airframe and the deformation of several structural beams. The flight departed Perth Airport headed north to Nifty aerodrome, with the expectation of a few thunderstorms along the way.
