On any given day, there are some 35,000 active NOTAM circulating in the global air transport system. In 2020, the total number of NOTAM issued exceeded 1.7 million.
Yearly totals such as this have increased steadily over the years, on average by more than 100,000 annually. Due to the COVID pandemic, however, the total number of NOTAM decreased by five percent in 2020, the first decrease in over 10 years (Source: Eurocontrol, International NOTAM statistics 2000-2020).
It is not uncommon for a pre-flight briefing package supporting a long-haul international flight to contain more than 100 pages of NOTAM information. Findings have shown that twenty percent of these will be old NOTAM, exceeding their three-month applicability period.
On 8 April 2021 at 12:00 UTC, ICAO launched a new Global Campaign on NOTAM Improvement (NOTAM2021) by kicking off Phase 1 on old NOTAM with a webinar in collaboration with its seven regional offices. The objective is the significant reduction in the number of old NOTAM still in circulation.

A NOTAM is defined as "a notice distributed by means of telecommunication containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations" (Annex 15 - Aeronautical Information Services).
How does the NOTAM2021 campaign address quality of NOTAM?
The first phase of the NOTAM2021 campaign on NOTAM improvement focusses on one quality issue affecting NOTAM, namely old NOTAM. The intent is to address the widespread misuse of NOTAM to promulgate information with validity exceeding three months. Eliminating old NOTAM does not imply that the overall quality of NOTAM is improving, nor does the global campaign replace or substitute a State's quality management system (QMS) obligation for AIS. All provisions for the quality management of aeronautical information still apply. For details see Annex 15, Chapter 3.6, Quality management system, and PANS-AIM (Doc 10066), Chapter 3, Quality management.
