The Knowledge Base tool offers multiple knowledge models to access all kinds of information. As a consequence, different users might see different results when searching in the Knowledge Base.

It enables rapid knowledge-based searches to quickly resolve client's issues and can be accessed by means of the Helpdesk button on the EAD Explorer button bar.

EAD Knowledge Base

Users can search for a solution in the database by typing in keywords in the search field provided or they can browse among the Top Solutions and find an answer to their request.

A list of relevant documents according to the search criteria or keywords will then be displayed in the main panel.

Alternatively, documents can be browsed by subsystem (SDO, INO, PAMS, Charting etc.)

Service Desk

EAD Service Desk

The EAD Service Desk responds to clients' (DP & DU) enquiries for operational as well as service and general requests and to manage problems associated with any aspect of the services offered by the service provider.

It is available 24 hours a day, 7 days a week and deals with both operational and technical issues. Find it here.



SIGMA, the SDO Input Guidance Manual, provides a single point of entry to all relevant SDO data maintenance information. It is a support tool for EAD Data Providers during their migration process to the EAD as well as for operational data maintenance.

It is a CMS based system and covers complementary static data encoding rules part of AICM/AIXM rules with some additional EAD/SDO specific rules. Additionally, it gives references regarding where to find data in the AIP and other relevant information and is applicable for both ECIT and ESI clients.

As such, SIGMA addresses the EAD Data Providers need for a single access to all material supporting them in the static data maintenance, enabling them to enter AIS data and better understand the aeronautical information provision into SDO. The SIGMA gateway offers several information access gates: 

  • the SDO perspective view, with descriptions and definitions and referenced information to the AIP specimen annex SDO rules;
  • the eAIP Specimen view with links to the SDO view; 
  • the Rules view with an overview of all SDO Rules with additional information on the applied rule; 
  • and additional technical training material. 

EAD Data Users can also take full benefit from SIGMA, as a primary source in understanding harmonisation objectives and different rules applied in the EAD and AICM/AIXM data models.
