EUROCAE ED-230 PDF

This standard provides:

a. interoperability requirements for the B2 ATN ground system to provide FANS 1/A aircraft with B2 data link services, as defined by the B2 SPR Standard [4]. See paragraph 1.2.1.

b. interoperability requirements to ensure seamless transition of ATS communications for bilingual aircraft (i.e., aircraft equipped with FANS 1/A and ATN data link technologies transitions from a FANS 1/A ground system to a B2 ATN ground system and vice versa). See paragraph 1.2.2.

NOTE:

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

2. Some B2 ATN ATSUs may elect only to provide data link services to FANS 1/A aircraft (CHAPTER 3), only to provide seamless transfer to FANS airspace (CHAPTER 4) or to provide both (CHAPTER 3 and CHAPTER 4). Some FANS 1/A ATSUs may elect to provide seamless transfer to ATN airspace (CHAPTER 4).

3. FANS 1/A and ATN bilingual aircraft may elect to support saemless transfer to ATN and FANS 1/A airspace (CHAPTER 4).

PURPOSE

This document provides the interoperability requirements for an aeronautical telecommunication network for Baseline 2 ATS data communication services (B2) ground system that provides B2 air traffic data link services to future air navigation system 1/A (FANS 1/A) aircraft in oceanic and continental airspaces.

NOTE: Based on ED-78A/DO-264 [1], 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.
