NOTICE: Part VI
DOCUMENT ACTION: Notice of availability and request for public comment.
SUBJECT CATEGORY:
Proposed Advisory Circular (AC) 20-HIRF, The Certification of Aircraft Electrical and Electronic Systems for Operation in the High Intensity Radiated Field (HIRF) Environment
DATES: Comments must be received on or before May 2, 2006.
DOCUMENT SUMMARY:
This notice announces the availability of, and requests comments on proposed Advisory Circular (AC) 20HIRF, The Certification of Aircraft Electrical and Electronic Systems for Operation in the High Intensity Radiated Field (HIRF) Environment. This proposed AC provides information and guidance concerning an acceptable means, but not the only means, of showing compliance with the High Intensity Radiated Field (HIRF) Notice of Proposed Rulemaking (NPRM) published in the Federal Register on February 1, 2006, regarding the operation of electrical and electronic systems on an aircraft when the aircraft is exposed to an external HIRF environment.
SUMMARY:
Transportation Department, Federal Aviation Administration,
SUPPLEMENTAL INFORMATION
Comments Invited
Interested persons are invited to comment on the proposed AC listed in this notice by submitting such written data, views, or arguments as they desire to the above specified address. Comments received on the proposed AC may be examined, before and after the comment closing date, in Room PL401 on the plaza level of the Nassif Building, 400 Seventh Street, SW., Washington, DC, between 9 a.m. and 5 p.m. Monday through Friday, except Federal holidays, or on the DOT DMS Web site http://dms.dot.gov at any time. All communications received on or before the closing date will be considered by the Manager of the Aircraft Engineering Division, Aircraft Certification Service, before issuing the final Advisory Circular.
Background
The external HIRF environment exists because of the transmission of electromagnetic radio frequency (RF) energy from radar, radio, television, and other groundbased, shipborne, or airborne RF transmitters. Because of the vulnerability of aircraft electrical and electronic systems to interference from the electromagnetic RF energy generated by these transmitters, the FAA proposes to add airworthiness standards to protect these systems from this external HIRF environment. This proposed AC provides designers, manufacturers, and installers, with general information and acceptable means to show compliance with the FAA's proposed HIRF airworthiness regulations.
