This space is dedicated to the further development of the Digital NOTAM Specification and of the automatic NOTAM production guidelines.
An initial version 1.0 was published in 2011 and it is available on the www.aixm.aero web site. That version was used for trials and test implementations, in particular in the context of the SESAR project 13.2.2. Based on the feedback collected from these implementations, an updated version (2.0) is now in preparation, including both improvements to the previously scenarios and new coding scenarios.
The Digital NOTAM Specification 2.0 will contain only the AIXM 5.1.1 data coding scenarios.
The NOTAM Production rules for each scenario are only guidelines, which might be adapted to local practices. Elevating the NOTAM production rules to Specification status would de-facto standardise the NOTAM messages. This was outside the mandate of the Digital NOTAM Specification working group, which has drafted these coding/decoding scenarios.
