Removing Old NOTAM

The NOTAMeter is a tool to analyse the age of NOTAM issued by the 193 Member States. It distinguishes between Current (less than 3 months), Old (more than 3 months but less than 1 year), and Very old NOTAM (more than 1 year).

The graphs and tables below can be used to analyse old and very old NOTAM by ICAO region and State.

With your help, we can reduce the total number of NOTAM by 20% in one simple step - by removing old, non-compliant NOTAM.
