National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Design and Certification of Aircraft for the HERF Environment.

N9112575

Publication Date	1990
Personal Author	Glecier, J.; Cross, J. P.
Page Count	18
Abstract	Certification authorities world-wide are in the process of amending regulations to add new standards which will provide requirements for the protection of aircraft flight critical functions from the effects of high energy radiated electromagnetic fields (HERF). In late 1989, the Federal Aviation Administration (FAA) imposed requirements on the Beech Model 2000 Starship airplane requiring qualification of the installed equipment for operation in HERF conditions. Field levels imposed for aircraft certification to the HERF threat require hardening aircraft electronic systems to a level two orders of magnitude above today's typical equipment qualification levels. Two large design challenges are thereby imposed: (1) hardening equipment requires extraordinary measures to insure performance; and (2) conventional test methods and test equipment used for qualification are not capable of adequately assessing performance at the high field levels. HERF design considerations and solutions relative to the above subjects and the experience gained by Beech Aircraft during the Starship and subsequent development programs in evaluating flight critical system performance of aircraft certification in the HERF environment are discussed.
