US allocates $7B for aircraft upgrades

The U.S. Federal Aviation Administration (FAA) has announced that major American airlines must upgrade their altitude measurement devices on their aircraft by the end of 2030 to prevent interference from 5G signals, which could result in inaccurate altitude readings during landings in bad weather conditions. The costs of these upgrades will be covered with government support of up to $2.2 billion, with an expected expense of between $80,000 and $120,000 per aircraft, bringing the total cost to over $7.1 billion. The decision applies to flights operated by U.S. airlines within U.S. airspace, allowing a deadline until 2034 for civilian aircraft that are not registered domestically. The dispute began in 2022 when authorities warned of potential interference between 5G signals and altitude measurement devices, leading to flight cancellations or adjustments—particularly for Boeing 777 and 747-8 aircraft—after 5G spectrum was auctioned in 2021 for $80 billion. The measures aim to ensure flight safety during landings and prevent disruptions in air travel caused by signal interference.
