ACNS.B.DLS.B1.020 Data link services
ED Decision 2022/008/R
Community Specification EN 303 214 ‘Data Link Services (DLS) System’ provides a set of test scenarios to be demonstrated using a verified ground data link system or a ground data link system simulator.
(a) Data link initiation capability (DLIC) service
The DLIC service enables the exchange of information between aircraft and ground data link equipment, necessary for the establishment of data link communications. It ensures:
(1) the unambiguous association of flight data from the aircraft with flight plan data used by an ATS unit,
(2) the exchange of the supported air–ground application type and version information,
(3) the delivery of the addressing information of the entity hosting the application.
(b) ATC Communications Management (ACM) Service
The ACM service provides automated assistance to flight crews for conducting the transfer of ATC communications (voice and data). It includes:
(1) the initial establishment of CPDLC with an ATS unit;
(2) the CPDLC ATC transfer instruction from one ATS unit to the next ATS unit;
(3) the CPDLC ATC instructions for a change in voice channel;
(4) the normal termination of CPDLC with an ATS unit.
(c) ATC Clearances and Information (ACL) Service
The ACL service provides flight crews with the ability to:
(1) send requests and reports to air traffic controllers;
(2) receive clearances, instructions and notifications issued by air traffic controllers to flight crews.
(d) ATC Microphone Check (AMC) Service
The AMC service provides CPDLC ATC instructions to flight crew(s) requesting him/them to verify the status of his/their voice communication equipment
[Issue: CS-ACNS/4]
EASA aviation regulations define data link services (DLS) for air-ground communication. These services include data link initiation (DLIC), ATC communications management (ACM), ATC clearances and information (ACL), and ATC microphone check (AMC). DLS ensures unambiguous flight data association, application exchange, automated ATC communication transfer, and efficient information exchange between pilots and controllers.
