Key Takeaways:

The FAA's January 2023 NOTAM system outage, caused by a corrupted file, led to a U.S. airspace ground stop and prompted the House to pass the NOTAM Improvement Act, establishing a task force to enhance NOTAM presentation, accuracy, and cybersecurity.
The FAA has released a new, comprehensive Aviation Weather Handbook (FAA-H-8083-28), consolidating information from six previous advisory circulars to streamline weather guidance for pilots and operators.
The FAA issued InFO 23001 to clarify approach category guidance, stating that an aircraft's certificated approach category is permanent and does not change based on actual landing weight.

The aftereffects of the FAA’s January 11, 2023, Notam system outage continue to ripple through the industry. If you’re just joining us, you should know the FAA was forced to issue a ground-stop in U.S. airspace after Notams (notices to air missions) became unavailable during a glitchy system upgrade.

According to online sister publication AVweb.com, the system “got glitchy” during the afternoon of January 10. Troubleshooting revealed a “single corrupted file” on both the main and backup systems. Technicians were doing a reboot of the Notam system—which was taking longer than anticipated—when the decision was made to issue a ground stop early on the 11th. As AVweb noted, the ground stop “didn’t last long but the effect was far-reaching.”
