Air navigation and air traffic management are evolving towards advanced concepts, such as 4D trajectory management, space based navigation in the terminal area, etc. A common and accurate situational awareness is required by all actors. People and automated systems shall have access to and work with a common, up-to-date data set.

The aim of the Digital NOTAM project is to provide the standards, the framework, resources and a substantiated proof-of-concept for the full ECAC-wide implementation of the digital NOTAM concept, necessary to all ATM actors in order to support an accurate and always up-to-date common situational awareness of the aeronautical operations environment.
The digital NOTAM concept is an investment in the future, but with immediate practical benefits for the end users. It will bring new value to investments made in recent years, e.g. European AIS database, which delivers static data in digital format. It is a project with finalisation in the AIM domain when it comes to pre-flight briefing. Digital NOTAM can accommodate legacy system and improve the quality of the information provided to legacy NOTAM users.
The operational implementation is proposed to start by 2010, with an initial operational capability by end 2011.

Definition: "NOTAM - 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."
Today, temporary information in the NOTAM system is provided mainly as free text and it is loosely structured. This is incompatible with the increasingly automated aeronautical information management systems, which largely rely on timely, accurate and quality assured aeronautical data. Some of the drawbacks of the current NOTAM system are further discussed on the page linked below:

Definition: "Digital Aeronautical Information Update (Digital NOTAM) - a data set made available through digital services containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to systems and automated equipment used by personnel concerned with flight operations."
The Digital NOTAM encoding is based on the Aeronautical Information Exchange Model (AIXM) version 5, which has been developed in cooperation between EUROCONTROL and the United States Federal Aviation Administration (FAA), with the support of the international AIS community. More information about the digital NOTAM concept and its expected benefits is provided on the pages linked below:
