This DLASD deals with the "ATIS" ATS datalink service implementation as per the operational requirements as described in reference [1] and reference [11] § 4.3.5 to § 4.3.9.

It does not cover those experimental implementations of the "ATIS" ATS datalink service or "ATIS" re-transmissions by others providers than official Air Traffic Services, which are based on free text as well as on different ACARS message formats

The ATIS service is a "Flight Information Service" as defined in reference [11].

This document does not capture any requirement which would be applicable to the specific interface of communication between domains (e.g. X.25), even if that interface characteristics of low level may transcend a domain boundary (Refer to section A.1.1 in APPENDIX A). However it does identify, for information purposes, any document of relevance for the implementation of such communication interface.

This document is applicable to an operational environment where the communication services can be supported by communication links:

• which are provided by a single communication service provider,

• which rely partially on services proposed by other communication service providers.
