Radio frequency susceptibility testing for RTCA/DO-160D, after change notice one

RTCA/DO-160D, Environmental Conditions and Test Procedures for Airborne Equipment, defines a series of minimum standard environmental test conditions (categories) and applicable test procedures for airborne equipment. The purpose of these tests is to provide a laboratory means of determining the performance characteristics of airborne equipment in environmental conditions representative of those which may be encountered in airborne operation of the equipment. This paper is a follow-up to the paper covering DO-160D given by the author at the 1998 DASC, and provides a detailed description of the Radio Frequency susceptibility requirements in Change Notice One for Section 20 of RTCA/DO-160D. Background and rationale for the changes in Section 20 are also discussed from the author's perspective as a member of RTCA/Special Committee 135, Working Group 20 (WG-20), which is responsible for producing Change Notice One for DO-160D, Section 20.
