Traffic Symbol Other Proximate TA RA
TCAS Only
Thanks to the different ATSAW controls (refer to 3.6.5 – ATSAW Controls), the ATSAW symbols get different states (refer to Figure 3-12).
The extended label shows the flight number of the traffic. The full label shows the flight number, the ground speed, and the wake
vortex category (L: Light, M: Figure 3-12: ATSAW symbol labels
Medium, H: Heavy).
Note: The wake vortex category complies with the ICAO PANS-ATM definitions
(see References): LIGHT – aircraft with a MTOW less than 7 000 kg MEDIUM – aircraft with a MTOW between 7 000 kg and 136 000 kg HEAVY – aircraft with a MTOW more than 136 000 kg.
When a piece of information is missing in ADS-B messages (e.g. ground
speed), the piece of information is not displayed on ND.
When the position or the track is not available in ADS-B messages, the
corresponding ATSAW symbol:
-
For TCAS+ADS-B: Becomes a TCAS Only symbol.
-
For ADS-B Only: Is removed from ND.
Refer also to 3.6.4.2.4 – Combination of TCAS and ADS-B Information for other
cases when ATSAW symbols are not displayed.
A flight crewmember can highlight, select, or both highlight and select an ATSAW symbol. Refer to 3.6.5.2 – Traffic Selector.
