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.
Less than 12 hours after the Giants beat the Patriots on Sunday at the Indianapolis-hosted Super Bowl, area FBOs were just beginning to be able to enjoy their own victory celebrations. “The weather was great. The people were great. It was a fabulous experience,” said Andrea Montgomery, co-owner of Indianapolis Executive-based Montgomery Aviation. “We had to do a little de-icing at around midnight. We had pretty much everyone out of here by 2:30 a.m.
The FAA has issued an update to its 2010-2011 Ground Deicing Holdover Time Tables and Guidance on its website. The document contains a revised listing of the lowest operational use temperatures (Lout) for anti-icing fluids, which were supplied to the agency and Transport Canada by the fluid manufacturers.
Gulfstream has completed several icing certification test points on the G250. S/N 2001 has flown with simulated ice shapes applied to the non-heated areas of the aircraft, including the nose, tail, winglets and engine pylons. Meanwhile, S/N 2002 completed anti-ice system dry-air testing, paving the way for certification flight testing into known icing conditions, which at press time were expected to start in the U.S.
Improper de-icing procedures led to an accident that substantially damaged a Flexjet Challenger 300 last winter at Chicago Executive Airport, according to the NTSB. The Safety Board concluded that the operator of the de-icing vehicle did not adhere to company procedures and did not maintain clearance between the vehicle’s boom and the airplane during the de-icing operation.
The FAA’s Draft Advisory Circular 20-147A released last month provides new guidance to aircraft manufacturers on compliance with regulations covering engine induction system icing and engine installation ice requirements. Comments on the draft AC are due by November 1.
Cavu Companies has added a new hold-over time (Hot) module to its EFB-Pro performance software to help pilots ensure compliance with regulatory re quirements for ground anti-icing/de-icing fluid application and pre-takeoff icing checks. The Hot module costs $250 for the first year and $100 for annual renewal. Current EFB-Pro subscribers can upgrade for the $100 renewal price.
Proposed changes to FAR Parts 25 and 33 address dangerous icing conditions caused by supercooled large drops, including a requirement that manufacturers not only show that airplanes can operate safely in those conditions but also with specific performance and handling qualities. Changes would add new icing certification standards for engines and engine installations and components such
Proposed changes to Parts 25 and 33 address dangerous icing conditions caused by supercooled large drops including a requirement that manufacturers not only show that airplanes can operate safely in those conditions but also with specific performance and handling qualities and that “all new transport-category designs be able to fly in co
The FAA yesterday issued a final rule that prohibits Part 91K, 135 and 121 operators from taking off with “polished frost”–meaning frost buffed to make it smooth–on an aircraft’s wings, stabilizers and control surfaces. The new rule will take effect on Jan. 30, 2010. The FAA already prohibits major and regional air carriers from operating with polished frost.
