Atmospheric icing

October 21, 2014 - 6:00pm

Safe Flight Instrument of White Plains, N.Y., has developed an aircraft-based icing conditions detector (ICD) system using a combination of optical detection and a shielded temperature probe. The optical system uses an LED, a prism and an infrared sensor to detect the presence of moisture in the air.

Icing is one of aviation’s major hazards and one that has been a causal factor in numerous accidents. Between 1982 and 2000, it was instrumental in more than 550 accidents that resulted in over 800 fatalities. While the lift- and controllability degrading effects of ice accretion on flying and control surfaces are well known, the ability to detect icing as it occurs has been a more difficult issue.

In an effort to help corporate jet operators save money on anti-icing fluid treatment and cut down on wasted fluid application, Walter Randa, founder of Leading Edge Deicing Specialists, has developed a new Type IV anti-ice spray system.

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 (Booth 5251) introduced at EBACE 2014 its new Icing Conditions Detector (ICD). The patented optical ICD provides an alert that icing conditions exist before ice can accrete on the aircraft. Comprised of a single line replaceable unit, the system is ideal for operations in all modes of flight, according to Safe Flight.

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.

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.

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.
