The force moving an ejection seat must be sufficient to enable it to clear the tail of the disabled aircraft. To achieve this, the seat must accelerate from zero velocity to about 12.2 to 24.4 m/sec (40 to 80 ft/sec). This gives a rapid rate of rise of acceleration or jolt factor, which must remain …
An ejection seat is a rigidly constructed metallic seat, which is forcibly ejected from the aircraft cockpit by means of an explosive charge.
Escape from a crippled aircraft, be it a commercial aircraft, full of passengers, or a combat aircraft with one or two aircrew, ensuring a safe exit is the first and the paramount step towards survival. Unlike the combat aircraft with its ejection seats, transport aircraft, helicopter and most of the training aircraft, except jets, do …
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.
