NOTE: Always refer to the traffic display documentation for details on
how traffic information is depicted on each display.
Other Traffic (OT)
Other Traffic (OT) targets are typically displayed as a hollow diamond
and do not meet the criteria for any other traffic type.
Proximity Advisories (PA)
Proximity Advisory (PA) targets are typically displayed as a solid
diamond. PAs are defined as traffic within 6 NM horizontally and
1200 feet vertically that are not a Traffic Advisory.
Traffic Advisories (TA)
Traffic Advisory (TA) targets are typically displayed as a yellow circle
and are generated when the GTS predicts that a target may pose a
collision threat. Traffic Advisory sensitivity, criteria, and types are
described in the following sections.
Sensitivity Level
To prevent nuisance TAs in the airport environment, there are two sensitivity
levels available: Sensitivity Level A (SL A) and Sensitivity Level B (SL B). The
Sensitivity Level determines what criteria will be used for TAs. SL A is less
sensitive and traffic must be closer before it will generate an alert. SL B is more
sensitive and traffic may be farther away to generate an alert. The logic for
