A thermal imaging sensor where sensor output is based on [[infrared]] [[radiation]] (usually between 3-5 or 8-12 micron spectral range) generated by the external scene. FLIRs are used for [[targeting acquisition]] and aircraft pilotage on both the AH-64 Apache and the newly developed RAH-66 Comanche.
