Data link technology improves the efficiency of communications between controllers and pilots through supplementing voice communications with air-ground data link communications. On 30 September 2008 the Single Sky Committee has given a favourable opinion on the Implementing Rule on Data Link Services (DLS) in which the coordinated introduction of data link based on air-ground point-to-point data communications is described from 2011 onwards. The deployment of data link will also be the first major achievement that contributes to the first implementation  package (IP1) of the European Air Traffic Management Master Plan (the ATM Master Plan). The Implementing Rule on Data Link Services (DLS) is requiring the following services that should be operated over an ATN (Aeronautical Communication Network( and VDL (Very High Frequency Digital Link) Mode 2 infrastructure: 1.     DLIC - Data Link Initiation Capability (log on and contact) 2.     ACM - Air Traffic Control (ATC) Communications Management 3.     ACL - Air Traffic Control (ATC) Clearances 4.    AMC - Air Traffic Control (ATC)  Microphone Check The related European standards will be developed in accordance with the implementing rule on data link services and in line with the EUROCONTROL Specification on Data Link Services.
