Undoubtedly cabin pressurisation and oxygen systems have allowed unhindered aviation activities, with a caveat though – never to cross the altitude beyond the capabilities of the system on board. Thus, commercial aircraft fly maintaining a cabin pressure of 6000-8000 ft, and unpressurised small aircraft mostly operate below 10000 ft. Combat aircraft may have a higher …
The most important effects of hypoxia is on Central Nervous System (CNS) and vision. This insult to CNS which affects the performance in flight varies as per the altitude and the resulting stages of hypoxia. The effects are discussed as per the stages of hypoxia.
Technological improvements in reliability and performance of cabin pressurisation and Oxygen delivery systems has greatly reduced the incidents and accidents due to hypoxia. Yet, incidence of hypoxia in flight still occurs due to lack of vigilance, mechanical failure of equipment, improper indoctrination or improper use of oxygen equipment.
On a flight in 2010, the aircrew – two pilots and five flight attendants, smelt a kind of dirty socks odour while boarding their flight. Not knowing about the source or cause of this foul odour, they undertook the flight. But on landing the entire crew and few passengers needed emergency medical care. Both the …
