aircraft

Aircraft power systems endure dramatic electrical events—voltage surges, frequency shifts, and sudden dropouts during engine transitions. Power line testing ensures avionics can withstand these harsh conditions, from flight-critical computers that must survive 50ms power failures to everyday equipment that keeps passengers comfortable at 30,000 feet.

Can you use everyday electronics on an aircraft, or do they need special military-grade testing? Patrick Andre examines when commercial off-the-shelf equipment works fine versus when it could fail catastrophically in demanding environments like military aircraft and helicopters.

This article explains HIRF certification testing for aircraft, detailing transfer function measurement methods like LLDD and LLSF. It outlines how induced current measurements determine airframe attenuation and how test limits vary based on equipment criticality and aircraft size.RetryClaude can make mistakes.

Part 3 of our HIRF series examines four electromagnetic test environments protecting aircraft, explains certification levels based on failure severity, and demonstrates how understanding aircraft shielding can reduce cost and weight while maintaining safety standards.

The FAA has published requirements that require testing for all battery devices that are a part of the aircraft itself.

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.

SAE International has recently published ARP60493, a Guide to Civil Aircraft Electromagnetic Compatibility (EMC). The guide details information, guidance, and methods for demonstrating EMC on civil aircraft.

Manufacturers supplying the aerospace industry face the decision whether to become AS 9100 certified.

The Council of the International Civil Aviation Organization (ICAO) has endorsed a proposal that...
