PURPOSE.

This notice provides guidance material relevant to certification of aircraft operating in High Intensity Radiated Field (HIRF) environments. Aircraft are exposed to the HIRF environments that result from high-power radio frequency transmitters such as radio and television broadcast stations, radars and satellite uplink transmitters. This notice provides a standard and uniform set of requirements for aircraft HIRF certification until a final rule can be issued. The Notice of Proposed Rulemaking (NPRM) is being developed by the FAA/JAA Electromagnetic Effects Harmonization Working Group of the Aviation Rulemaking Advisory Committee (ARAC). Aircraft electrical and electronic systems or equipment addressed by this notice may be new designs, significant modifications of existing designs, or new applications of existing systems or equipment that have not been previously certified for HIRF. This notice supersedes previous HIRF guidance.
