US Aviation Regulator Mandates Upgrade to Protect Against 5G Interference
The FAA has published its final rule requiring aircraft operating in US airspace to use interference-tolerant radio altimeters, capable of withstanding 5G wireless signals. The rule mandates the replacement or upgrade of approximately 58,500 radio altimeter units across roughly 40,700 aircraft, with Part 121 airlines and large foreign carriers needing to comply by the end of 2030, and other operators by roughly 2034. The move aims to resolve the long-standing conflict between 5G expansion and aviation safety, as reported by Skyfarer.
