scope:

This document provides the operational, safety, and performance requirements for data link services that support specific ATS functions in oceanic and remote airspace. Figure 1-2 provides an overview of the scope of the ATS functions and data link services as it relates to the air traffic services and communication, surveillance, and navigation components.

PURPOSE

This document defines and allocates the set of minimum requirements for the operational, safety, and performance aspects for implementations of air traffic data link services in oceanic and remote airspace. Allocation is done by this SPR standard to the necessary elements of the CNS/ATM system.

This SPR standard is intended for use with interoperability requirements (INTEROP) standards, and the guidelines described in ED-78A/DO-264.

NOTE: Based on ED-78A/DO-264, INTEROP and SPR standards provide recommendations intended for government organizations, conference of governments, or agencies having statutory jurisdiction over the use and provision of data link services. These recommendations are for use by such government organizations to enunciate official policy related to such matters in aeronautical information publications (AIPs), notices to airmen (NOTAMs), airplane flight manuals (AFMs), and operator specifications.
