The internal stakeholders of the EAD are divided into two groups.

The internal clients are all those EUROCONTROL directorates, units, programmes, and services that will be clients of the Service and with which a Service Level Agreement will be established. The internal Service clients will comprise:

• the Central Flow Management Unit (CFMU), which will be the biggest service consumer of the EAD,
• Bretigny,
• the EATMP Database,
• CRCO,
• UAC Maastricht.

The EAD will also service most EUROCONTROL Agency units and programmes. An evaluation done in 1997 has shown that 12 different internal clients are clearly interested in the service.

Other EUROCONTROL directorates, units, programmes, and services that are not clients of the Service, however, will be internal stakeholders or the EAD due to the influence their deliverables have on the EAD development and further evolutions or due to the enabling function of the EAD, i.e. the Airspace Management domain (FUA, FRAP), the AIS AHEAD Programme and the Nav Programme.
