.
Selects (flight number in cyan on MCDU) the aircraft on ND. Refer to Figure 3-13, Figure 3-19, Figure 3-21, and Figure 3-23.
3.6.5.2. TRAFFIC SELECTOR
The flight crew uses the Traffic Selector to highlight or select an ADS-B symbol on ND. There is one Traffic Selector on either side of the cockpit for each flight crew member.
3.6.5.2.1. Turn to highlight
The flight crew turns the Traffic Selector to highlight an ATSAW symbol on ND. The TCAS computer highlights aircraft as in Figure 3-13. A flight crewmember can highlight only one aircraft at a time on his ND. A quick turn of the Traffic Selector removes the highlight.

3.6.5.2.2. Pull to select
The flight crew pulls the Traffic Selector to select an ATSAW symbol on ND. Refer to Figure 3-32. The flight crew can select only one aircraft at a time on ND. The selection is shared on both NDs. The flight crew pushes the Traffic Selector to deselect an ATSAW symbol.
3.7. OPERATIONAL RECOMMENDATIONS FOR ATSAW
3.7.1. FOR THE AIRLINE
. Train your flight crews to use the ATSAW function in conjunction with ATSAW applications (ATSA AIRB, ITP, VSA).
. Pay particular attention to the flight crew training related to ATSA ITP. The flight crew must be aware of ATSA ITP basics (terminology, phraseology, ITP criteria, normal and contingency procedures, etc).
3.7.2. FOR THE FLIGHT CREW
.
Do NOT use the ATSAW function for self-separation and collision avoidance. The ATSAW function is an awareness tool that assists the flight crew for the visual acuiqistion of surrounding aircraft capable of ADS-B OUT.
.
Apply the TCAS procedures when a TA or RA occurs. Responsibilities do not change. ATC remains responsible for aircraft separations.
.
Always correlate ATSAW information with visual information out of the window. Do not maneuver with information from the ATSAW function only.
3.8. REGULATIONS FOR ATSAW
At the time of writing the present brochure, there is no mandate for the carriage of the ATSAW function.
3.9. MANUFACTURER FOR ATSAW
To fulfill the Traffic Awareness function with ATSAW, AIRBUS proposes the following two systems: the Honeywell TPA 100B (available from early 2010) and the ACSS T3CAS (available from early 2010). These TCAS computer capable of ATSAW are also compliant with TCAS II Change 7.1 (refer to 3.1.6 – TCAS II Change 7.1).
ATSAW ITP is an option of ATSAW.

3.10. FUTURE APPLICATIONS
3.10.1. ATSA SURF WITH OANS
AIRBUS is currently developing the integration of the ATSA SURF application in the OANS (refer to 5.1 – Description of OANS) for all AIRBUS aircraft. The ATSA SURF application will provide the traffic around the aircraft on the OANS moving map. The ATSA SURF application will improve taxi operations (e.g. anticipation of aircraft queue for take-off) and safety on ground (i.e. traffic awareness during taxi with low visibility).
