It’s a simple concept: if you can flight plan a higher altitude to use during an overwater emergency, then you might not need as much extra fuel to reach an alternate airport. Most airlines and business jet operators flight plan for an emergency altitude of 10,000 feet, because supplemental oxygen isn’t needed at that altitude, when flying from the equal-time point to an alternate airport.
Sherwin-Williams Aerospace Coatings (Booth No. 4547), located in Andover, Kan., introduced several new products during NBAA’12. Its new urethane primer and sanding surfacer (CM0481827) can double as either a traditional sanding surfacer or as a primer. MROs and paint shops can now use one product for two purposes. And the product dries twice as fast as traditional epoxy surfacer technologies. The corrosion-inhibitive urethane primer is also chromate hazard-free and is intended for use on all aircraft.
Duncan Aviation of Lincoln, Neb. (Booth No. 5580), a provider of airframe inspections, engine maintenance, cabin and cockpit systems retrofits, painting and interior work, as well as pre-owned aircraft sales and acquisitions, has acquired several examples of a dry-ice blasting machine to accomplish a specific service bulletin for its Bombardier Challenger customers.
Bauhaus Luftfahrt, a Germany-based aerospace think tank, has outlined its vision of an electrically powered, emission-free airliner–relying on batteries–that it believes could be in service by 2035. The most obvious aspect of the design is a C-shaped wing for greater lift. Another major feature is the use of superconductivity for better power transmission and greater motor power density.
Skyscapes, a new basecoat/clearcoat exterior paint developed by Sherwin-Williams Aerospace, now has two complete coatings, including pretreatment, corrosion protective primer, topcoat and clearcoat. Both are certified with SAE International’s Aerospace Material Specification 3095 (AMS 3095). One system includes Alodine, 483987 primer and Skyscapes basecoat/clearcoat. The second system is Alodine, 483787 chrome hazard-free primer and Skyscapes basecoat/clearcoat.
The U.S. Air Force will gradually lift flight restrictions placed on its Lockheed Martin F-22 Raptor fleet in response to unexplained incidents of hypoxia, or oxygen deprivation, experienced by pilots dating as far back as 2008.
The FAA has issued an airworthiness directive for certain Bombardier Challenger 300s as a result of reports of deformation found at the neck of the pressure regulator body on the oxygen cylinder and regulator assembly (CRA). It requires an inspection to determine if a specified oxygen CRA is installed and to replace affected oxygen CRAs.
Russia’s VSMPO-AVISMA Corp., specialist manufacturer of products made of titanium and aluminum alloys, steel and nickel, and Shanghai Aircraft Manufacturing Co. (SAMC), have signed a long-term purchase contract for titanium forging products for the Comac C919 aircraft program.
A seven-month investigation by the U.S. Air Force Scientific Advisory Board into unexplained hypoxia, or oxygen deprivation, incidents experienced by F-22 pilots has not determined the root cause of the problem, the service said March 29. The investigation did produce a number of safety recommendations, and the Air Force continues to study the problem.
The photo of a badly burned Apple iPhone that circulated after the phone caught fire during a Regional Express flight has raised important questions about lithium-ion battery safety among a wide aviation audience. The incident occurred after the Regional Express Saab 340B landed in Sydney, Australia, on Nov.
