This guide provides detailed information, guidance, and methods related to the Federal Aviation Administration (FAA) Advisory Circular (AC) 20-158 and European Aviation Safety Agency (EASA) draft Advisory Material Joint (AMJ), both titled "The Certification of Aircraft Electrical and Electronic Systems for Operation in the High-Intensity Radiated Fields (HIRF) Environment". The AC provides acceptable means, but not the only means, of compliance with Title 14, Code of Federal Regulations (14 CFR) 23.1308, 25.1317, 27.1317, and 29.1317, High-Intensity Radiated Fields (HIRF) protection for Aircraft Electrical and Electronic Systems, and applicable FAA HIRF Special Conditions to prevent hazards to aircraft electrical and electronic systems due to HIRF produced by external transmitters. It is also intended for this guide to provide the same information, guidance, and methods to the European Aviation Safety Agency (EASA) interim HIRF policies certification requirements.
This guide is neither mandatory nor regulatory in nature and does not constitute a regulation or legal interpretation of the regulation. The information in this guide represents a collection of best engineering practices that have been used to certify aircraft HIRF protection. An applicant may elect to establish an alternative method of compliance that is acceptable to the cognizant airworthiness authorities.
This document is consistent with the guidance in FAA AC 20-158. The AC 20-158 and draft HIRF AMJ may be referenced in aircraft certification requirements such as JAA/EASA certification review items. While this document is generally consistent with AC 20-158 and draft HIRF AMJ, users of this document should verify that the guidance in this document is acceptable to the cognizant airworthiness authorities.
This revision incorporates changes throughout that are consistent with new Federal Aviation Administration HIRF certification regulations and certification guidance adopted in 2007. It also includes revised test methods that were developed after the original release of this ARP. The organization of the ARP was revised to be consistent with the certification steps described in AC 20-158.
Due to the extensive re-work and re-organization of this revision the standard ‘change bar’ indications for the changes are not shown, therefore, an ‘R’ has been placed before the document title.

AE-4 Electromagnetic Compatibility (EMC) Committee
It is the duty of the AE-4 Electromagnetic Compatibility (EMC) Committee to produce advisory materials for the aerospace community in the following areas: Electromagnetic Compatibility (EMC), Electromagnetic Interference (EMI), and High Intensity Radiated Field (HIRF) environments
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
