Can’t breath in the F-22 ? This may happen…

News broke that the F-22 fleet is standing down until further notice. The reason? A pilot nearly collapsed due to the lack of oxygen… Other pilots complained about hypoxia and decompression sickness, demonstrating they were not getting enough oxygen. Worse, this lack of oxygen may be the reason one F-22 crashed in November, killing the pilot. Whilst the fleet of F-22 is standing down, numerous testing are been done. The surprising thing is that this was not detected before, during previous tests, both in flight and in simulators. One of the arguments put forward is that testing could have been done mainly in simulators.

However Tom Christie, former DOT&E Director said “”It’s not something you simulate. It either works or it doesn’t.” Even when these systems are working, an interview with aerospace and operational physiologist Capt. Matthew Taranto at the Las Vegas Sun explains that pilots must train their bodies to be able to tolerate 15 seconds of intense acceleration pressing down on them (9 G-forces) to resist oxygen deprivation to their brain.
