Standard Specification for High Intensity Radiated Field (HIRF) Protection in Small Aircraft
ABSTRACT
This specification applies to the high intensity radiated field (HIRF) protection aspects of airworthiness and design for ”small” aircraft. It establishes the Aircraft Type Code (ATC) compliance matrix based on airworthiness level, number of engines, type of engine(s), stall speed, cruise speed, meteorological conditions, altitude, and maneuvers. An ATC is defined by taking into account both the technical considerations regarding the design of the aircraft and the airworthiness level established based upon risk-based criteria. The requirements described by this specification for HIRF protection cover electrical and electronic systems that perform a function whose failure would prevent the continued safe flight and landing of the aircraft; electrical and electronic systems that perform a function whose failure would significantly reduce the capability of the aircraft or the ability of the flight crew to respond to an adverse operating condition; and the HIRF environments and equipment HIRF test levels for electrical and electronic systems.
SCOPE
1.1 This specification covers international standards for the high intensity radiated field (HIRF) protection aspects of airworthiness and design for “small” aircraft.
1.2 The applicant for a design approval must seek the individual guidance for their respective civil aviation authority (CAA) body concerning the use of this specification as part of a certification plan. For information on which CAA regulatory bodies have accepted this specification (in whole or in part) as a means of compliance to their Small Aircraft Airworthiness regulations (hereinafter referred to as “the Rules”), refer to ASTM F44 webpage (www.astm.org/committeee/F44.htm), which includes CAA website links. Annex A1 maps the Means of Compliance described in this specification to EASA CS-23, amendment 5, or later, and FAA 14 CFR Part 23, amendment 64, or later.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
