The DLIC service shall enable the exchange of the necessary information for the establishment of data link communications between ground and aircraft data link systems.
The DLIC service shall be available to support:
the unambiguous association of flight data from the aircraft with flight plan data used by an ATS unit,
the exchange of the supported air–ground application type and version information,
and the delivery of the addressing information of the entity hosting the application.
The exchanges between airborne and ground data link systems for the execution of DLIC service shall comply with:
operating methods, time sequence diagrams and messages for the DLIC initiation and DLIC contact functions specified in Section 4.1 of the Eurocae document identified in point 11 of Annex III,
safety requirements specified in Section 4.2.2 of the Eurocae document identified in point 11 of Annex III,
performance requirements specified in Section 4.3.2 of the Eurocae document identified in point 11 of Annex III.
The ACM service shall provide automated assistance to flight crews and air traffic controllers for conducting the transfer of ATC communications (voice and data) comprising:
the initial establishment of CPDLC with an ATS unit,
the transfer of CPDLC and voice for a flight from one ATS unit to the next ATS unit, or to instruct a change of voice channel within an ATS unit or sector,
the normal termination of CPDLC with an ATS unit.
The exchanges between airborne and ground data link systems for the execution of ACM service shall comply with:
operating methods and time sequence diagrams specified in Sections 5.1.1.1.1 to 5.1.1.1.7 and 5.1.1.2 of the Eurocae document identified in point 11 of Annex III,
safety requirements specified in Section 5.1.2.3 of the Eurocae document identified in point 11 of Annex III, excluding requirements relating to downstream clearance,
performance requirements for the en route phase specified in Section 5.1.3.2 of the Eurocae document identified in point 11 of Annex III.
The ACL service shall provide flight crews and controllers with the ability to conduct operational exchanges comprising:
requests and reports from flight crews to air traffic controllers,
clearances, instructions and notifications issued by air traffic controllers to flight crews.
The exchanges between airborne and ground data link systems for the execution of ACL service shall comply with:
operating methods and time sequence diagrams specified in Sections 5.2.1.1.1 to 5.2.1.1.4 and 5.2.1.2 of the Eurocae document identified in point 11 of Annex III,
a common subset of the message elements specified in Section 5.2.1.1.5 of the Eurocae document identified in point 11 of Annex III as appropriate to the en route operational environment,
safety requirements specified in Section 5.2.2.3 of the Eurocae document identified in point 11 of Annex III,
performance requirements for the en route phase specified in Section 5.2.3.2 of the Eurocae document identified in point 11 of Annex III.
The AMC service shall provide air traffic controllers with the capability to send an instruction to several data link equipped aircraft, at the same time, in order to instruct flight crews to verify that their voice communication equipment is not blocking a given voice channel.
This instruction shall only be issued to those aircraft tuned to the frequency that is blocked.
The exchanges between airborne and ground data link systems for the execution of AMC service shall comply with:
operating methods and time sequence diagrams specified in Sections 5.3.1.1.1, 5.3.1.1.2 and 5.3.1.2 of the Eurocae document identified in point 11 of Annex III,
safety requirements specified in Section 5.3.2.3 of the Eurocae document identified in point 11 of Annex III,
performance requirements specified in Section 5.3.3.2 of the Eurocae document identified in point 11 of Annex III.
