SAFETY AND PERFORMANCE REQUIREMENTS STANDARD FOR AIR TRAFFIC DATA LINK SERVICES IN CONTINENTAL AIRSPACE (CONTINENTAL SPR STANDARD)
|Publication Date:||1 May 2004|
This document includes the definition of data link services, the environmental conditions relevant to the implementation of those data link services in continental airspace, and the operational, safety, and performance requirements for using the data link services. The data link services are:
a) Data Link Initiation Capability (DLIC)
b) Data link services for ATC communications:
• ATC Communication Management (ACM) ·
• ATC Clearance (ACL) ·
• ATC Microphone Check (AMC)
• Departure Clearance (DCL)
• Downstream Clearance (DSC)
c) Flight Information Service (FIS):
• Data Link Automatic Terminal Information Service (D-ATIS)
d) Data link services for surveillance
• Flight Plan Consistency (FLIPCY)
NOTE 1: The scope is limited to the requirements for operational data link services and related ATS functions when operations, safety, and performance are relevant to the air traffic services. Assumptions for the environment and other ATS functions may be stated when necessary to establish the operational, safety and performance requirements for the data link services that are within the scope of the document.
NOTE 2: This SPR standard is intended to provide the basis for demonstrating that an implemented system, considering its inherent design and technologies, can meet the relevant operational, safety, and performance requirements for the data link services described in this document. It is not intended to limit the use of an implementation only to the data link services and operational context defined herein. However, in cases where it is intended to support additional or define new data link services, the operational, safety and performance requirements for such operational contexts and/or new data link services will need to be established as a basis for approval qualification of the implemented systems.
NOTE 3: Requirements related to securing data link services that would provide for protection against malicious or intentional behavior causing harm are beyond the scope of this document.
NOTE 4: Requirements related to the recording of data communications for accident/incident investigation purposes are beyond the scope of this document.
