DATA-LINK APPLICATION SYSTEM DOCUMENT (DLASD) FOR THE "OCEANIC CLEARANCE" DATA-LINK SERVICE
|Publication Date:||1 March 2004|
This DLASD deals with the "Oceanic Clearance" ATS datalink service implementation as per the operational requirements as described in Ref 1.
It does not cover those experimental implementations of the "Oceanic Clearance" ATS datalink service, which are based on free text as well as on different ACARS message formats.
The OCL service is an "Enroute Control Service", a direct communication from Aircrew to OACC Traffic Controller, as defined in Ref 11.
This document does not capture any communication requirement which would be applicable to the specific interface between Communication and ATS domain (e.g. X25), even if the low level interface characteristics may transcend a domain boundary (c.f. Section A.1 in ANNEX A ). It however identifies, 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 one or more communication service provider,
• which rely partially on services proposed by other communication service providers.
