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.

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.

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 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.

Responding to new Environmental Protection Agency guidelines that could eventually become law, Octagon Process has developed a Type 1 de-icer fluid that uses less propylene glycol than typical fluids. According to Octagon president Joe McGrail, when propylene glycol gets into wetlands, it breaks down and microorganisms form and attack the glycol.

As airports across the U.S. wage their annual struggle against winter weather, business aviation operators may soon find themselves familiar with a new de-icing method. Forced-air de-icers, which use high-volume, low-pressure air to help strip contamination from flying surfaces, have been used to augment the effect of glycol on airliners at major airports for years, but the business aircraft community has been slow to embrace them.

UK-based Kilfrost, which is celebrating 66 years since it helped introduce the first in-flight de-icing systems to keep wings frost and ice free, has developed DFsustain [The initials DF stand for de-icing fluid.–Ed.] from a corn-based glycol called Susterra, developed by DuPont Tate and Lyle BioProducts, rather than the more traditional crude-oil derived glycol.
