FAA Orders U.S. Airlines to Upgrade Aircraft Altimeters by 2030
The Federal Aviation Administration (FAA) has ordered major U.S. airlines to retrofit aircraft with upgraded radio altimeters by the end of 2030 to reduce the risk of interference from expanding wireless spectrum used for 5G services.
The move comes ahead of a planned auction of additional wireless spectrum and is designed to ensure aircraft navigation systems continue to provide accurate altitude readings during critical phases of flight.
Up to $2.2 Billion in Government Rebates
To help offset the cost of the required upgrades, eligible airlines can receive up to $2.2 billion in government rebates.
The funding is intended to support carriers as they replace or modify existing equipment to meet the FAA's next-generation performance standards.
Why the Upgrades Are Needed
Radio altimeters measure an aircraft's height above the ground and play a vital role during takeoff, landing, and low-visibility operations.
According to the FAA, older altimeters may be vulnerable to interference from certain 5G wireless signals, potentially leading to inaccurate altitude readings.
The updated standards are designed to improve resistance to signal interference and enhance overall aviation safety.
Industry Deadline Set for 2030
The FAA has given airlines until December 31, 2030, to complete the retrofits across their fleets.
The long implementation period is expected to allow carriers sufficient time to schedule maintenance, install upgraded equipment, and minimize operational disruptions.
