US Sets 2024 Deadline For 5G Signal Safeguards On Aircraft

US aviation safety regulators intend to require passenger and cargo aircraft to meet requirements by early next year for navigation gear to deal with potentially unsafe interference from 5G mobile-phone signals. Bloomberg reports: The equipment is needed because the newer wireless signals are on frequencies near those used by planes' radio altimeters, which determine altitude over ground and can cause them to malfunction, the Federal Aviation Administration has found. Wireless companies are eager for a solution because they paid the government more than $80 billion for the new airwaves. The changes would need to be made by Feb. 1, 2024, the agency said in a notice (PDF) Monday. The FAA said it couldn't rule out interference from 5G signals for about 100 incidents of aircraft navigation equipment issuing erroneous data. Such situations will increase as telecommunications providers expand 5G coverage throughout the US, the FAA said. [...] The FAA estimates that out of 7,993 US-registered aircraft that would need revisions, approximately 180 would require radio altimeter replacements and 820 would require the addition of filters to comply with the proposed order, at an estimated cost of as much as $26 million.
