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).
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.
Sunday marked the 10th anniversary of the Payne Stewart accident, in which the 42-year-old professional golfer and five others aboard a chartered Learjet 35 lost their lives after the jet suffered a loss of pressurization during a flight from Orlando, Fla., to Dallas. All aboard the Learjet fell unconscious from the effects of hypoxia about 15 minutes after departing Orlando International Airport.
October 25 marks the 10th anniversary of an event that shocked the worlds of aviation and golf when one of the game’s greats–Payne Stewart–lost his life after the Learjet in which he was traveling suffered a loss of pressurization during a flight from Orlando to Dallas.
The National Transportation Safety Board has dispatched investigators to examine a Southwest Airlines jet after it made an emergency landing in West Virginia yesterday after a hole opened in the body of the airplane and the cabin lost pressure.
Altitude chamber training is now being offered by MedAire at Arizona State University. The Tempe, Ariz.-based medical emergency response firm said the stand-alone, five- to six-hour course–available on demand–costs $995 per person and covers physiology, hypoxia, oxygen systems, altitude sickness and the physical effects of flight and decompression.
For aviators and their passengers, oxygen means life at the high altitudes traversed by modern aircraft. True high-altitude passenger flight wasn’t really practicable until large-cabin pressurization was introduced during the halcyon days of aeronautical development surrounding World War II, most notably aboard the Boeing 307 Stratoliner and Lockheed Constellation transports and Boeing B-29 bomber.
A proposed AD calls for inspections of the front and aft surfaces of the pressure dome on Pilatus PC-12s for cracking and other damage that would have to be repaired. The proposal is based on 19 reports of nicks and scratches on pressure domes on the turboprop single caused by drill or rivet tools. The FAA said the damage could lead to rapid decompression. The AD would apply to 280 U.S.-registered PC-12s.
