An individual who possesses an exceptional academic record, physical fitness, healthy well-being, and a strong mental drive will have a higher chance of being selected for pilot training.
Fighter pilots must be in optimal health to handle the physical demands of modern aerial warfare.
Excellent heart condition is required, as the increased "G's" a pilot experiences in a turn can cause stress on the cardiovascular system.
Pilots need to be in good shape in order to handle the high G-forces caused by aerial combat.
[citation needed] Many early air-to-air and surface-to-air missiles had very simple infrared homing ("heat seeking") guidance systems with a narrow field of view.
Because modern jet aircraft are highly agile and have the capacity to make very sharp turns, the pilot's body is often pushed to the limit.
If the forces are great enough and over a sufficient period of time this can lead to blackouts (called G-induced loss of consciousness or G-LOC), because not enough blood is reaching the pilot's brain.
To counteract this effect pilots are trained to tense their legs and abdominal muscles to restrict the "downward" flow of blood.
Modern flight suits, called G-suits, are worn by pilots to contract around the extremities exerting pressure, providing about 1G of extra tolerance.
The exceptions being Turkey where Sabiha Gökçen became the first female fighter pilot in history in 1936 and went on to fly fast jets well into the 1950s,[4] and the USSR during the Second World War 1942–1945 where many women were trained as fighter pilots in the 586th Fighter Aviation Regiment including Lilya Litvyak who became the top scoring woman ace of all time with 12 kills and Katya Budanova a close second with 11 kills, although both were killed in combat.
