UPDATE: The FAA has announced it will miss its December 2024 target for ICAO-format NOTAMs, with implementation now expected in late 2025.
The FAA is making a significant shift in how Notices to Air Missions (NOTAMs) are formatted, aligning with International Civil Aviation Organization (ICAO) standards. This transition, set for implementation in Winter 2024, aims to enhance global standardization, improve flight planning, and ensure pilots receive accurate and actionable NOTAMs in a consistent format.
What’s Changing?
Currently, FAA NOTAMs follow a domestic format that differs from the ICAO structure used internationally. While the FAA has already been providing ICAO-formatted NOTAMs for familiarization, this transition will make the ICAO format the official standard for all U.S. NOTAMs.
Benefits for Pilots & Operators
- Standardization: NOTAMs will now have the same format for both domestic and international flights, reducing confusion for pilots flying across different regions.
- Improved Access: Enhanced sorting and filtering capabilities will help flight planning service providers deliver more relevant NOTAMs.
- Global Integration: Aligning with ICAO standards promotes seamless coordination with other Air Navigation Service Providers (ANSPs).
Preparing for the Transition
Pilots, dispatchers, and operators should familiarize themselves with the ICAO NOTAM format, which includes structured fields for NOTAM type, location, and validity. Resources, including monthly stakeholder meetings, are available via the FAA's NOTAM website.
