Trafc Status Banner
Annunciation
Description
TA OFF SCALE
A Trafc Advisory is outside the selected display range.*
Annunciation is removed when trafc comes within the selected
display range.
TA X.X ± XX ↕
System cannot determine bearing of Trafc Advisory.**
Annunciation indicates distance in nm, altitude separation in
hundreds of feet, and altitude trend arrow (climbing/descending).
AGE MM:SS
Appears if trafc data is not refreshed within 6 seconds.
If after another 6 seconds data is not received, trafc is removed
from the display.
The quality of displayed trafc information is reduced as the age
increases.
TRFC COAST
The displayed data is not current (6 to 12 seconds since last
message).
The quality of displayed trafc information is reduced when this
message is displayed.
TRFC RMVD
Trafc is removed because it is too old for coasting (12 to 60
seconds since last message).
Trafc may exist within the selected display range, but it is not
displayed.
TRFC FAIL
Trafc data has failed.
NO TRFC DATA
Trafc has not been detected.
TRFC UNAVAIL
The trafc service is unavailable or out of range.
