De-icing fluid manufacturer Kilfrost has reported orders for its “environmentally driven” Sustain products in New Zealand, with Air New Zealand and Aviall purchasing 27 metric tons of them over the last year. “All our sustainable products offer significant environmental benefits in terms of carbon savings and low toxicity, with no compromise in terms of performance and functionality,” said CEO Gary Lydiate.
Canada’s National Research Council (NRC) has added new capabilities to its altitude icing wind tunnel (AIWT), such as simulating flights at 25,000 feet and the addition of hot air supply for models that use it for de-icing. The improvements will help NRC meet client demands for development and certification work recognized by regulators such as Europe’s EASA and the U.S. FAA.
Canada’s National Research Council (Hall 4 Stand C18B) has been flight-testing its Dassault Falcon 20 fueled by biofuel while sampling the exhaust using a probe fitted to a Lockheed T-33 chase plane. The NRC believes the exercise to be a world first.
Kilfrost (Hall 4 Stand G4) is introducing what it claims to be the first aircraft de-icing fluid made from sustainable sources. The new corn-based DF Sustain fluid is an environmentally friendly alternative to monopropylene glycol and it has already been approved by aviation authorities in the U.S. and Japan.
The Environmental Protection Agency (EPA) has finalized new regulations that will provide relief to airports where de-icing fluid is used. The EPA had proposed more stringent de-ice effluent limitations in 2009, but the agency has incorporated voluntary pollution-reduction programs, according to the Airports Council International-North America (ACI-NA).
Anti-icing surfaces under development at GE and EADS could one day reduce and possibly even eliminate the need for existing anti-icing techniques. Research organizations at the two major aerospace companies are currently working on surfaces that would naturally repel ice without using energy.
GE Global Research presented new findings on nanotextured anti-icing surfaces and coatings last week at the American Physical Society Conference in Boston. While there are many applications for this technology, aircraft are at the top of the list.
As the investigation continues into Tuesday’s fatal crash of a Daher-Socata TBM700 in New Jersey, more details of the flight’s final moments are emerging. According to the NTSB, the pilot reported that he was “picking up ice” just before the single-engine turboprop crashed into the treed median of I-287 near Morristown, killing all five on board.
Taking a proactive approach toward the anti-icing regulations proposed by the FAA in June 2010–and still unscheduled for adoption into the FARs–Spirit AeroSystems (Booth No. C11720) has been working with Wichita State University and an undisclosed supplier to develop two new anti-icing systems for nacelles surrounding large aircraft engines.
The FAA has finally put a regulatory nail in the coffin of ice bridging with a new rule requiring Part 121 airline pilots to activate deicing systems at the first indication of ice accumulation.
