The FAA has issued an airworthiness directive (AD) for the Bombardier Challenger 300 prompted by reports of deformation found at the neck of the pressure regulator body on the oxygen cylinder and regulator assembly (CRA). The AD requires an inspection to determine if a certain oxygen CRA is installed and the replacement of affected oxygen CRAs.
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 U.S. Air Force approved a resumption of flight operations by the Lockheed Martin F-22 Raptor, ending a four-month standdown ordered after pilots experienced symptoms of hypoxia. The suspected source of the problem, the aircraft’s onboard oxygen generation system (Obogs), remains under study.
The U.S. Air Force’s F-22 Raptor fleet remains grounded into a fourth month as the Air Force Scientific Advisory Board conducts a study of the F-22 and other aircraft using onboard oxygen generation systems (Obogs).
The FAA is abdicating its safety responsibility.
Embry-Riddle Aeronautical University has taken delivery of a Mentor advanced aircraft training device built by Frasca. The trainer will be used in studies of hypoxia, or oxygen deprivation, in the university’s Normobaric lab. The Mentor replicates a Cessna 172 cockpit complete with Garmin G1000 avionics and a Truvision visual system.
Oxygen bottle levels are an important preflight item, but even with a full bottle, pilots still need to do some calculating to determine if there is enough oxygen for a planned flight and in case of a diversion. Aeronautical Data Systems (ADS), exhibiting at the Pacific Precision Products booth (No.
How much oxygen do you need to make sure you’re not only legal for a planned flight but can also safely provide for crew and passengers in the event of a diversion? Aeronautical Data Systems (ADS), based in Upper Saddle River, N.J., has developed Web-based software that helps answer this question easily and comprehensively.
In recent months FAA Administrator Babbitt has promoted specific tailored hypoxia training, along with high-altitude handling, for commercial and private pilots who want to fly at high altitude. Indeed, FAA Title 14 of the Code of Federal Regulations (14CFR) establishes mandatory requirements for high-altitude training using military altitude chambers at 15 U.S.
More than 60 percent of business jet pilots do not use oxygen masks when required to by FAA regulations, according to a survey conducted by corporate pilot Chris Shaver for his master’s thesis at Embry-Riddle Aeronautical University.
