(ta)
TAs are issued for traffic when they are predicted to be within a specified volume of
airspace around the aircraft in a specified amount of time. The protected volume and
time interval varies based on the current geodetic altitude and groundspeed. Thus, the
protected volume of airspace increases with altitude and ground speed. Refer to the
following table for details.

Traffic Advisories
TRAFFIC ALERTS (ADS-B TIS-B)
A traffic audio alert is generated whenever the number of Traffic Advisories on the
aera display increases. Limiting Traffic Advisories only reduces the “nuisance” alerting
due to proximate aircraft. For example, when the first Traffic Advisories appear on the
display, the user is alerted audibly. So long as a single aircraft remains on the display,
no further audio alert is generated. If a second (or more) aircraft appears on the
screen, a new audio alert is sounded. Traffic Advisories can only be issued when the
weather/traffic device knows its own altitude and the altitude of the intruder aircraft.
If the number of Traffic Advisories on the traffic display decreases and then increases,
a new audio alert is sounded. The traffic audio alert is also generated whenever TIS-B
service becomes available. The following traffic audio alerts are available:
• “Traffic”—TIS-B/ADS-B traffic alert received.
• “Traffic Not Available”—TIS-B/ADS-B service is not available or out of range.
