Typical Scope:

EAD is the world's largest Aeronautical Information System, a centralised reference database of quality-assured aeronautical information. EAD provides access to worldwide NOTAM and related static data, as well as access to AIP information in both PDF and AIXM format for the ECAC region. 

The EAD Portlet provides direct links to EAD Basic and EAD Pro:

EAD Basic is the EAD general access for private pilotes, general aviation, training schools and any member of the public searching for aeronautical information.

EAD Pro is the database's service for professional, high-volume users such as air operators, airlines, aviation service companies and Aeronautical Information Services (AIS) data providers. EAD Pro is available on a dedicated terminal (ECIT) or through a secure internet connection using SSL technology.
