This page holds the discussion on the information aspects of the service. It focuses on:

understanding the information offered by the service (information definition)
the filtering offered by the service.

Information Definition

The table allocates AIXM features to an ICAO digital data set (AIP, AMD, IFP, OBS). The list of features in the table comes from https://ext.eurocontrol.int/aixm_confluence/display/ACG/Feature+types+allocation+to+data+set.

It then states if the feature is required within a specific event encoding based on

The result is used to decide if the feature is in the scope of the services being defined by A3SG.

To support all services, an aeronautical information store will need the items marked as 'y'

Aeronautical Information Request Service

The service will cover the same aeronautical information that is available in the three ICAO digital data sets.

Aeronautical Aerodrome Map Request Service

The service generates maps based on AIXM features.

Digital NOTAM Subscription and Request Service

The service will allow a service consumer to subscribe to event scenarios based on https://ext.eurocontrol.int/aixm_confluence/display/DNOTAM/Coding+scenarios.

The aeronautical information made available is driven by the scenarios.

There is an OTHER Event Scenario that allows for anything even if not tied to an AIXM feature.
