![]() ![]() Better-than-average visual acuity is also a highly desirable and valuable trait. 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. Some air combat maneuvers form the basis for the sport of aerobatics: Normally, the facts of an enemy's weapon payload is unknown, and are revealed as the fight progresses. 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. ![]() ĭogfighting at 1 to 4 miles (1,600 to 6,400 m) 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". 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 RWR (radar warning receiver) to discern the types of signals hitting their aircraft. When maneuvering fiercely during engagements, pilots are subjected to high G-force. G-forces express the magnitude of gravity, with 1G being equivalent to Earth's normal pull of gravity. 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. ![]() When executing a "positive G" maneuver like turning upwards the force pushes the pilot down. The most serious consequence of this is that the blood in the pilot's body is also pulled down and into their extremities. ![]()
