The Global Campaign on NOTAM Improvement (NOTAM2021) was launched on 8 April 2021 with Phase 1 on old NOTAM. The virtual launch was in English only. The objective was to eliminate the number of old NOTAM still in circulation. 

Additional webinars will be conducted on a bi-monthly basis to monitor progress and share experiences and lessons learned. The overall schedule for these webinars is below.  To register for an event, please click on any of the dates below: 
All webinars will be conducted at 12:00 UTC to optimize global participation options. 


On any given day, there are some 35,000 active NOTAM in the global air transport system. In 2020, the total number of NOTAM issued exceeded 1.7 million. Findings have shown that twenty percent of these are old NOTAM, exceeding their three-months applicability period as per Annex 15 - Aeronautical Information Services. 

The NOTAMeter, a web-based software tool developed by ICAO, will be introduced during these webinars. The NOTAMeter distinguishes between current NOTAM, i.e. less than three months duration, old NOTAM, i.e. those exceeding three months but less than one year, and very old NOTAM, i.e. those NOTAM exceeding one year duration. The NOTAMeter will be used throughout the campaign to monitor progress.
