flare

i. A maneuver carried out just before touchdown to reduce the rate of descent, so that the aircraft settles on the runway smoothly and with the least amount of vertical speed. Normally referred to as flare-out.
ii. A magnesium candle supported by a small parachute, which was at one time carried by most aircraft operating at night. This flare was fired if it became necessary to force land. The burning flare produced sufficient light to enable a pilot to see the ground for making a landing. Flares are pyrotechnic devices used for signaling or to provide illumination.
iii. A cone-shaped expansion on the end of tubing. Tubing used in aircraft fluid lines flared at an angle of 37°.
iv. Infrared flares meant to deflect incoming infrared missiles.
v. A waveguide in which one or both transverse dimensions increase toward the aperture. Also called a horn.
vi. As it relates to aerial photography, light reaching the photosensitive emulsion, resulting from internal reflections within the lens, such as occur from a noncoated air-glass lens surface.
