This AIR points out that above a frequency called the “transition frequency,” variances associated with the shielding effectiveness measurements can become large. It includes the derivations to demonstrate this. This fact should be taken into account when designing shielding for use above the transition frequency.
This Aerospace Information Report (AIR) is intended to provide information relating to the construction, calibration, and usage of parallel plate transmission lines in electromagnetic compatibility susceptibility testing.
The purpose of this AIR is to acquaint the aerospace industry with problems in attaining electromagnetic compatibility on gas turbine engines, particularly as used in aircraft. It is also the purpose of this AIR to present guidelines for the application of EMC controls to the engine, to its components which of necessity must operate in very hostile environments and to its interface with the aircraft.

This SAE Aerospace Information Report (AIR) is a description of methods to be employed to achieve Electromagnetic Compatibility (EMC) of gas turbine engine accessories. Its primary objectives are to aid those system designers of gas turbine assemblies who are employing commercial accessories, which are not always EMC designed, and to outline methods of achieving EMC employing readily available test instrumentation.
This SAE Aerospace Information Report (AIR) is a description of methods to be employed to achieve Electromagnetic Compatibility (EMC) of gas turbine engine accessories. Its primary objectives are to aid those system designers of gas turbine assemblies who are employing commercial accessories, which are not always EMC employing readily available test instrumentation. Electromagnetic Compatibility (EMC) as defined for this AIR is the ability of all engine accessories to perform within their specified capabilities when subjected to an electromagnetic environment generated by adjacent engine accessories.
This checklist is to be used by project personnel to assure that factors required for adequate system electromagnetic compatibility are considered and incorporated into a program. It provides a ready reference of EMC management and documentation requirements for a particular program from preproposal thru acquisition. When considered with individual equipments comprising the system and the electromagnetic operational environment in which the system will operate, the checklist will aid in the preparation of an EMC analysis. The analysis will facilitate the development of system-dependent EMC criteria and detailed system, subsystem, and equipment design requirements ensuring electromagnetic compatibility.
This specification covers the general requirements for conventional AC and/or DC current carrying filter networks for the reduction of electromagnetic interference. A conventional filter is defined herein as a component containing definitive, lumped, R-L-C components and not employing distributed parameters as a required characteristic.
