A team of Harvard University researchers has devised a product that prevents ice and frost from forming on metal surfaces such as the leading edge of an aircraft wing.

Surfaces treated with the non-toxic, non-corrosive Slips (for slippery liquid infused porous surfaces) become ultra smooth, slippery surfaces to which fluids and solids alike, such as condensation, frost and even ice, will not adhere.

The Slips technology–tested so far on refrigerator fans–has also been proven to work effectively under high-humidity and high-pressure conditions.

The UK’s Air Accidents Investigation Branch released factual details yesterday on the fatal crash of an AgustaWestland A109E helicopter in central London last week, highlighting the poor visibility the pilot was facing. The light twin hit a 719-foot-high crane jib at 7:59:25 a.m., killing the pilot and one person in the street below. It was flying back to Redhill after an aborted attempt to land at Elstree aerodrome.

Less than two months after two possible weather-related fatal crashes of EMS helicopters in Illinois and Iowa, the FAA has issued a Special Airworthiness Information Bulletin covering recommendations for rotorcraft 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 neither equipped nor approved for flight into icing conditions.

Pilots who operate ADS-B-equipped aircraft in any of seven U.S. terminal airspace regions can now take advantage of free air traffic advisories and weather information. The areas include Fairbanks (FAI) in Alaska; Lansing (LAN) in Michigan; Moses Lake (MWH), Pasco (PSC) and Yakima (YKM) in Washington state; as well as Waterloo (ALO) in Iowa; and Youngstown (YNG) in Ohio.

A revised FAA Notice 8900.196 has been published to provide inspectors with information on de-icing fluid holdover times, as well as a list of the fluids themselves and recommendations on various other ground deicing/anti-icing issues. While the primary audience is flight standards district office (FSDO) principal operations inspectors responsible for air carrier de-icing programs, it is also of value to FSDO personnel and aircraft operators.

In the wake of recent revisions to the FAA’s 2012-2013 deicing holdover tables, NBAA is encouraging aircraft operators and service providers to review the changes, which could affect their procedures as winter weather arrives. The new guidance includes small changes to rated holdover times and the length of time an aircraft may wait to depart following application of an approved de-icing fluid.

Direct hurricane hits on Florida FBOs are rare, but all of them prepare.

A new turbulence-detection and -avoidance system now operating at Juneau International Airport (JNU) in Alaska is expected to be adapted for additional U.S. airports beginning with those most often affected by dangerously unstable air. Juneau often closes during bouts of significant turbulence to avoid risk to people, cargo and aircraft.

When Gulfstream’s G650 enters service later this year, pilots will find a pleasant surprise, a Honeywell RDR 4000 3-D weather radar that is far easier to operate than earlier systems. The radar has been flying for a few years on airliners, and the G650 is the first business jet application. New features just implemented on the RDR 4000 include turbulence detection, hail and lightning display and a new attenuation display.

With fall approaching in the northern hemisphere, the FAA has issued Notice 8900.196, a revised document offering updates to the agency’s deicing program for the coming winter flying season. The update includes holdover times as well as a list of deicing and anti-icing fluids.
