The B412 Film Cooled Tailpipe (B412 FCT) significantly reduces IR signature at most view angles around the aircraft. The device fits within the factory cowling and installation requires no modifications to the airframe. Ease of interchangeability allows the FCT to be used as a mission kit, with less than 15 hours required for the installation. The B412 FCT is fully qualified and currently in service on B212 and B412 helicopters in five different countries.
