THE PENTAGON — The Navy has appointed former commander of Carrier Air Wing 3 and F/A-18 Hornet pilot Capt. Sara Joyner to lead the service’s effort to research and prevent physiological episodes in its fixed-wing aircraft, amid progress this summer collecting data to help understand the root cause of these PE events, Vice Chief of Naval Operations Adm. Bill Moran told USNI News on Wednesday. Read More
The following is the June 21, 2017 CRS Insight brief to Congress, Out of Breath: Military Aircraft Oxygen Issues.
The Air Force recently grounded some of its newest aircraft, F-35A strike fighters, due to incidents in which pilots became physiologically impaired with symptoms of oxygen deficiency while flying. Although the root cause of the F-35 incidents has not yet been established, the grounding has renewed attention on hypoxia, a physical condition caused by oxygen deficiency that may result in temporary cognitive and physiological impairment and possible loss of consciousness. Hypoxia has affected pilots of F-22, F/A-18, and T-45 aircraft in recent years. Read More
This post has been updated to include additional comment from Vice Chief of Naval Operations Adm. Bill Moran in a phone call with reporters.
A comprehensive review of the rising number of physiological episodes and the Navy’s response to those PEs determined the Navy’s oxygen-generation and cabin pressure systems are too complex for reliable performance, and that the process for reporting and investigating the root cause of physiological episodes is “fundamentally flawed,” according to the review released this afternoon.
