For aerial decoy flares magnesium rich compositions are used with Mg contents between 55 and 65 wt%. At these stoichiometries only a part of the applied Mg reacts with the PTFE. The surplus Mg is vaporised and reacts with the atmospheric oxygen; likewise the thermally excited soot reacts with the atmospheric oxygen:
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.
The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile. Conventional man-portable air defense systems ( MANPADS )-launched missiles include an infrared sensor that is sensitive to heat, for example the heat emitted from an aircraft engine.
Strontium nitrate – most common oxidizer/colorant for red colors in flares, fires, and stars; strontium also serves as a stabilizer for the mixtures. [4] At lower temperatures (with organic fuels) produces strontium nitrite ash which can smother the flame; decomposes completely at higher temperatures (with magnesium).
This particular model uses 26.5-millimeter (1.04 in) flares (manufactured by Patel Ballistics). In the civilian world, flares are commonly used as signals, and may be ignited on the ground, fired as an aerial signal from a pistol-like flare gun, or launched from a self-contained tube. Flares are commonly found in marine survival kits.

If an aircraft needed to loiter over a high risk area or was flying slowly (as helicopters do), it would require a large number of flares to decoy any missile fired at it. The IRCM provided constant protection against infra-red guided missiles. The ALQ-144 and ALQ-147 were first delivered to the US military in 1981. Currently there are over ...
An environmentally friendly red-light flare was a pyrotechnic (firework) flare which used lithium-based formulations that emitted red light. A flare is used for signaling, illumination, or defensive countermeasures in civilian or military applications. It is based on a non-hygroscopic (not absorbing air) dilithium nitrogen-rich salt that served ...
