Keywords: hirf /emc, test technologies, flight clearance, mobile test stations

The HIRF / EMC testing purpose is to confirm that aircraft specific equipment and subsystems can correctly operate both within their own environment and with respect to potential external electromagnetic disturbances. Test activities are performed to reach the desired degree of confidence in releasing the required aircraft flight clearances, according to international standards. Alenia Aerospazio has developed test facilities and a EMC test range which are suitable to perform conducted tests and radiated tests, also in a frequency range such that the wavelengths are in the order of ,magnitude of thee aircraft dimension. The paper describes the test facilities, mainly including Mobile Test Stations, the EMC Test Range, and fixed/mobile antennas. Some relevant examples of methodology application on actual aircraft are presented.
