A fighter pilot or combat pilot is a military aviator trained to engage in air-to-air combat, air-to-ground combat and sometimes electronic warfare while in the cockpit of a fighter aircraft. Fighter pilots undergo specialized training in aerial warfare and dogfighting (close range aerial combat). A fighter pilot with at least five air-to-air kills becomes known as an ace.
Recruitment
Fighter pilots are one of the most highly regarded and desirable positions of any air force. Selection processes only accept the elite out of all the potential candidates. 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. Candidates are also expected to exhibit strong leadership and teamwork abilities. As such, in nearly all air forces, fighter pilots, as are pilots of most other aircraft, are commissioned officers.
Fitness
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. One "G" is equal to the force of gravity experienced under normal conditions, two "G"s would be twice the force of normal gravity. Some fighter aircraft can accelerate to up to 9 G’s. Fighter pilots also require strong muscle tissue along the extremities and abdomen, for performing an anti-G straining maneuver (AGSM, see below) when performing tight turns and other highly accelerated maneuvers. Better-than-average visual acuity is also a highly desirable and valuable trait.
Tactics
Offensive
Modern medium and long range active radar homing and semi-active radar homing missiles can be fired at targets outside or beyond visual range. However, when a pilot is dogfighting at short-range, his position relative to the opponent is decidedly important. Outperformance of another pilot and that pilot's aircraft is critical to maintain the upper-hand. A common saying for dogfighting is "lose sight, lose fight".
If one pilot had a greater missile range than the other, he would choose to fire his missile first, before being in range of the enemy's missile. Normally, the facts of an enemy's weapon payload is unknown, and are revealed as the fight progresses.
Some air combat maneuvers form the basis for the sport of aerobatics:
Basic
Split S
Immelmann turn
Thach Weave
The Scissors
Chandelle
Complex
Pugachev's Cobra
Herbst maneuver
Defensive
Pilots are trained to employ specific tactics and maneuvers when they are under attack. Attacks from missiles are usually countered with electronic countermeasures, Flares and chaff. Missiles like the AIM-120 AMRAAM, however, can actively home in on jamming signals.
Dogfighting at is considered "close". Pilots perform stressful maneuvers to gain advantage in the dogfight. Pilots need to be in good shape in order to handle the high G-forces caused by aerial combat. Pilots flex their legs and torso to keep blood from draining out of the head. This is known as the AGSM or the M1 or, sometimes, as the "grunt".
Defense against missiles
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. These missiles could be avoided by simply turning sharply, which essentially caused the missile to lose sight of the target aircraft. Another tactic was to exploit a missile's limited range by performing evasive maneuvers until the missiles had run out of fuel.
Modern infrared missiles, like the AIM-9 Sidewinder, have a more advanced guidance system. Supercooled infrared detectors help the missile find a possible exhaust source, and software assists the missile in flying towards its target. Pilots normally drop flares to confuse or decoy these missiles by creating more multiple heat signatures hotter than that of the aircraft for the missile to lock onto and guide away from the defending aircraft.
Radar homing missiles could sometimes be confused by surface objects or geographical features causing clutter for the guidance system of either the missile or ground station guiding it. Chaff is another option in the case that the aircraft is too high up to use geographical obstructions. Pilots have to be aware of the potential threats and learn to distinguish between the two where possible. They use the radar warning receiver (RWR) to discern the types of signals hitting their aircraft.
