FAA mandates 5G-compatible altimeter retrofits for US airlines with $2.2B reimbursement program

The FAA has mandated that all U.S. aircraft altimeters be upgraded by 2030 to mitigate interference from C-band 5G signals. The $2.2 billion reimbursement program, funded by spectrum auction proceeds, aims to offset the financial burden on carriers while ensuring flight safety against inaccurate altitude readings.
