An Overview of Aerospace Battery Compliance

The United States Federal Aviation Administration (FAA) has published requirements that require testing for all battery devices that are a part of the aircraft itself. This testing is heavily based on standards published by RTCA and includes primary and secondary lithium, nickel, and sealed lead chemistries.

New Lightning Hazards to Consider for Aircraft Certification

The evolution of E and H fields on aircraft struck by lightning is a complex process. An October 2014 in-flight lightning strike is reviewed in this article as an example that inspires a fresh look at how lightning E and H fields should be considered for indirect effects certification.

Electromagnetic Compatibility Assessment of Wireless Emissions in Shipboard Spaces

Electromagnetic compatibility of wireless communications and sensor networks with mission critical electronic equipment is assessed for below-deck spaces on ships and submarines. With intentional wireless emission of radio-frequency (RF) energy into the reverberant spaces, it is necessary to measure and characterize the statistical electromagnetic environment (EME) and to predict maximum electric field strengths to a specified confidence level.
