Global Campaign on NOTAM Improvement

Global Campaign on NOTAM Improvement

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 objective of the campaign will be the significant reduction in the number of old NOTAM still in circulation.

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.
