FAA Completes First Phase of NOTAM Overhaul (faa.gov)

The FAA has completed phase one of its Notices to Airmen modernization, moving the system to the cloud in April 2026 and shutting down the legacy US NOTAM System as thousands of users transitioned to the new service. The overhaul comes more than a year ahead of the late-2027 timeline previously projected. The next phase will retire the Federal NOTAM Service later this year, making the new system the single authoritative source for the more than 4 million NOTAMs issued annually.
