Avionic systems performing critical functions in modern aircraft are potentially susceptible to the hazards of electromagnetic radiation from ground and airborne transmitters. The Federal Aviation Administration (FAA) requested that the Society of Automotive Engineers (SAE) coordinate the development of procedures and guidance material which can be used during the aircraft certification process to ensure adequate protection against High Intensity Radiated Fields (HIRF). This paper addresses the technical challenge of drafting a certification procedure and guidance standard, and the management process used by the SAE subcommittee AE4R to converge a diverse range of opinions by its international membership in the shortest possible time.

The NASA-LeRC under the direction of DOE is responsible for the test and evaluation of electric and hybrid vehicle propulsion systems and components. In September 1978, a contracted effort was undertaken with the General Electric Company to design, fabricate, and deliver a propulsion system breadboard of the GE-NTEV (ETV-1). This breadboard is currently under test in the LeRC Road Load Simulator and its operational characteristics are the subject of this paper. THE ELECTRIC TEST VEHICLE-ONE (ETV-1) was built by General Electric Company and Chrysler Corporation for the U.S. Department of Energy (DOE) to represent an electric vehicle designed and built from the ground up with present state-of-the-art technology. Two vehicles were built and are presently being evaluated by NASA's Jet Propulsion Laboratory (JPL). Some results of these JPL tests are also being presented at this conference.
