The Fairchild Republic A-10 Thunderbolt II has superior maneuverability at low speeds and altitude because of its large wing area, high wing aspect ratio, and large ailerons. The aircraft can loiter for extended periods and operate under 1,000 ft ceilings. It typically flies at a relatively slow speed of 350 mph, which makes it a much better platform for the ground-attack role. Engine exhaust passes over the aircraft's horizontal stabilizer and between the twin tails, decreasing the A-10's infrared signature and lowering the likelihood that the aircraft can be targeted by heat-seeking missiles fired from the ground. The ailerons are at the far ends of the wings to gain greater rolling moment, as with many aircraft, but there are two distinguishing features. The ailerons are larger than is typical, almost 50% of the wingspan, providing improved control even at slow speeds. The aileron is also split, making it a deceleron. (Wikipedia)
