However, the Low level test requires a complex analytical modeling approach to ensure compliance. An applicant may elect to establish an alternative method of compliance that is acceptable to the cognizant airworthiness authorities.
This process uses a direct drive method up to the first airframe electrical resonance, and a radiated field test methods above the first airframe resonance. While this document is generally consistent with AC and draft HIRF AMJ, users of this document should verify that the guidance in this document is acceptable to the cognizant airworthiness authorities. Generally, 2-D and 3-D computational models of the airframe up to the first electrical resonance are required. This requires several factors to be considered prior to testing such as the need for specialized high power test equipment, aircraft system instrumentation and flight emulation, RF hazards regarding fuel ignition and personnel exposure and adherence to national RF transmission rules and regulations.
HIRF Testing of Aircraft Systems
Often times the aircraft size prohibits the use of conventional anechoic lined EMI test chambers and special permits are 55883 for performing the testing process outdoors.

Your Alert Profile lists the documents that will be monitored. This approach is preferred over high aep testing for its reduced RF exposure levels and RF hazard considerations.

Models are required to estimate the level of influence ground plane coupling will have on low level swept current test results, especially where it is impractical to elevate the aircraft safely due to its size. However, these changes give rise to myriad new concerns related to electromagnetic interference EMI of critical on-board electronic systems.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. High Level Tests are performed using peak and average field levels determined for one of three particular HIRF environments over a test frequency range up to 18 GHz.
These concerns are based on the phenomena where electronic circuitry fails to operate as intended i. Subscription pricing is determined by: This guide is neither mandatory nor regulatory in nature and does not constitute a regulation or legal interpretation of the regulation.

HIRF Testing of Aircraft Systems April 5, Early aircraft designs typically consisted of a series of cables, chains, cranks and various other mechanisms to operate the systems which made the aircraft fly.
Due to increasing advancements in the field of electronics over the last 60 years, mechanical flight control devices are being replaced or augmented with electronic circuitry for enhanced accuracy, reliability and, most of all, human safety. Need more than one copy?
