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.

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.

A video showing lightning striking a Copa Airlines jet parked at the gate clearly demonstrates why all aircraft fueling ceases when thunderstorms are near. Pay particular attention to the small manhole cover near the front of the aircraft that goes flying toward a ground tug shortly after the strike.

The FAA is reissuing and revising a Special Airworthiness Information Bulletin (SW-08-03R4) covering recommendations for rotorcraft powered by turboshaft engines flying into snowy or icy conditions. The SAIB describes procedures to reduce the probability of an uncommanded in-flight engine shutdown due to snow and/or ice ingestion and reminds operators that most helicopters are not approved/equipped for flight into icing conditions.

Lockheed Martin (Stand 1975) is installing its WindTracer windshear and turbulence-detection system at Dubai International Airport (DXB), where it will be used to detect aircraft wake vortices, thus allowing for increased runway utilization. Two WindTracers have been installed this year and a third one is to follow in the first quarter of next year, Michael Margulis, WindTracer program director, told AIN. WindTracer is a long-range, 3-D-scanning pulsed doppler lidar-based system.

The families of victims of the October 1994 crash of an American Eagle ATR 72 into a field in Roselawn, Ind., met October 31 to remember their loved ones and discuss fundraising efforts to build a permanent memorial. All 68 people aboard American Eagle Flight 4184 died in the accident. The pilots lost control of the aircraft after it accumulated a significant amount of ice while flying at low speed in freezing rain in the holding pattern, a problem that triggered an autopilot disconnection while the aircraft was severely out of trim.
