A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust.
Alert or notification of an emergency in progress Position or location (or localization or pinpointing) of the party in distress. For example, a single aerial flare alerts observers to the existence of a vessel in distress somewhere in the general direction of the flare sighting on the horizon but extinguishes within one minute or less.

Target indicators, also known as target markers or TI's for short, were flares used by the RAF's Bomber Command during World War II. TIs were normally dropped by Pathfinders onto the target, providing an easily seen visual aiming point for the following "main force" of bombers to aim at. After their introduction, the use of TIs expanded to ...
A modern LUU-2B flare at 1,000 feet altitude illuminates the ground at 5 lux in a radius of 1500 feet. Burn time is 4–5 minutes. The flare is 36 inches long, 4.9 inches in diameter, and weighs about 30 pounds. A similar design called LUU-19B can provide covert illumination in the near-infrared (IR) spectrum with virtually no visual signature.
