ED Decision 2016/029/R
A2.1 Introduction
This Appendix amends ED-194A/DO-317B to address specific issues raised since publication of the document.
A2.2 TCAS II Integration with TSAA
TCAS integration is addressed in ED-194A/DO-317B section 2.2.4.5.3.3, titled ‘TSAA Traffic Caution alerts on Correlated TCAS Tracks’. Replace the current section 2.2.4.5.3.3 with the following text:
The TSAA application may be integrated with TCAS I, TCAS II, or TAS systems.
If an ADS-B/ADS-R/TIS-B track is correlated with a TCAS track, then the alerts shall (2223) only be presented from either the TSAA application or the TCAS system (i.e., not both).
If TSAA and TCAS II are installed on the same aircraft, TCAS II resolution advisories (RAs) shall (####) have priority over all other alerts.
If TSAA and TCAS II are installed on the same aircraft, TCAS II traffic advisories (TAs) shall (####) be generated for the TCAS tracks by the TCAS II TA function. TSAA may generate traffic alerts for ADS-B only traffic not correlated with a TCAS track.
TSAA alerts should take precedence over TCAS I or TAS traffic alerts (TAs) when the TCAS track is correlated with an ADS-B or ADS-R track; but, TCAS traffic alerts should take precedence over TSAA alerts when the TCAS track is correlated with a TIS-B track.
A2.3 TCAS Validation of ITP Traffic
TCAS validation of ITP traffic is addressed in ED-194A/DO-317B section 2.2.4.4.2.1, titled ‘Validation of Traffic Position with TCAS Data’. Add the following text to the end of the second paragraph.
ASSAP is not required to support ADS-R or TIS-B traffic for use with the ITP application.
A.2.4 TCAS Validation of CAVS Traffic
TCAS validation of CAVS traffic is addressed in ED-194A/DO-317B section 2.2.4.6.2.1, titled ‘Validation of Traffic Position with TCAS Data’. Remove all instances of the text ‘/ADS-R’ from this section and add the following text to the end of the second paragraph.
ASSAP is not required to support ADS-R or TIS-B traffic for use with the CAVS application.
[Amdt ETSO/12]
This Appendix amends ED-194A/DO-317B to specify TCAS II integration with TSAA, including alert precedence rules and ASSAP support exclusions for ITP and CAVS traffic.
