Guide to Civil Aircraft Electromagnetic Compatibility (EMC)

AE-4 Electromagnetic Environmental Effects (E3) Committee
  • Aerospace Standard
  • ARP60493
  • Current
Published 2017-10-25 by SAE International in United States
This guide provides detailed information, guidance, and methods for demonstrating electromagnetic compatibility (EMC) on civil aircraft. This guide addresses aircraft EMC compliance for safety and functional performance of installed electrical and electronic systems. The EMC guidance considers conducted and radiated electromagnetic emissions and transients generated by the installed electrical and electronic systems which may affect other installed electrical and electronic systems on the aircraft. Application of appropriate electrical and electronic equipment EMC requirements are discussed. Methods for aircraft EMC tests and analysis are described. This guide does not address aircraft compatibility with the internal electromagnetic environments of portable electronic devices (PED) or with the external electromagnetic environments, such as high-intensity radiated fields (HIRF), lightning, and precipitation static.

Coaxial Test Procedure to Measure the RF Shielding Characteristics of EMI Gasket Materials

AE-4 Electromagnetic Environmental Effects (E3) Committee
  • Aerospace Standard
  • ARP1705C
  • Current
Published 2017-02-09 by SAE International in United States
The purpose of this procedure is to establish a technique for reliably and repeatedly measuring the RF shielding characteristics of EMI gasket materials and EMI gaskets against various joint surfaces. The procedure is also used to test the reliability of the gasketed joint combinations after being subjected to hostile environments.

In-House Verification of EMI Test Equipment

AE-4 Electromagnetic Environmental Effects (E3) Committee
  • Aerospace Standard
  • AIR6236A
  • Current
Published 2016-08-01 by SAE International in United States
This AIR provides guidance to the EMI test facility on how to check performance of the following types of EMI test equipment: Current probe Line Impedance Stabilization Network (LISN) Directional coupler Attenuator Cable loss Low noise preamplifier Rod antenna base Passive antennas All performance checks can be performed without software. A computer may be required to generate an electronic or hard copy of data. This is not to say that custom software might not be helpful; just that the procedures documented herein specifically eschew the necessity of automated operation.

Stripline Test Method to Characterize the Shielding Effectiveness of Conductive EMI Gaskets up to 40 GHz

AE-4 Electromagnetic Environmental Effects (E3) Committee
  • Aerospace Standard
  • ARP6248
  • Current
Published 2016-02-19 by SAE International in United States
The purpose of this procedure is to establish a technique for reliably and repeatedly measuring the RF shielding characteristics of EMI conductive gasket materials and EMI conductive gaskets. Depending on the materials used for the construction of the measuring setup, the EMI conductive gaskets can be characterized against various joint surfaces. This standard will directly provide shielding effectiveness values up to 40 GHz, and will also be applicable for small samples of conductive EMI gaskets.
