EUROCAE ED-154A PDF

This standard provides:

a) Interoperability requirements for the ATN B1 ground system to provide FANS 1/A aircraft data link services, as defined by the Continental SPR Standard.

b) Interoperability requirements to ensure seamless transition of ATS communications for bilingual aircraft (i.e. aircraft equipped with FANS 1/A and ATN B1 data link technologies) transitions from a FANS 1/A ground system to an ATN B1 ground system or vice versa (e.g. FANS 1/A ground system providing data link services in an oceanic airspace and an ATN B1 ground system providing data link services in a domestic airspace).

NOTE 1: This standard provides a separated set of requirements for each of these two capabilities, which can be implemented and qualified independently.

NOTE 2: Some ATN B1 ATSUs might elect to comply with section 3 only, with section 4 only or with both section 3 and section 4. Some FANS 1/A ATSUs might elect to comply with §4. FANS 1/A and ATN B1 bilingual aircraft might elect to comply with section 4.

PURPOSE

This document provides the interoperability requirements for an aeronautical telecommunication network baseline 1 (ATN B1) ground system that provides air traffic data link services to future air navigation system 1/A (FANS 1/A) aircraft in continental airspace.

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 air traffic services supported by data communications. 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.
