TIS Symbology

TIS Symbol
Non-Threat Traffic
Proximity Advisory (PA)
Traffic Advisory (TA)
Traffic Advisory Off Scale
A Traffic Advisory (TA) alerts the crew to a potentially hazardous intruding
aircraft. Closing rate, distance, and vertical separation meet TA criteria. A Traffic
Advisory that is beyond the selected display range is indicated by a half TA
symbol at the edge of the screen at the relative bearing of the intruder.
TIS also provides a vector line showing the direction in which the traffic
is moving, to the nearest 45º. Traffic information for which TIS is unable to
determine the bearing (non-bearing traffic) is displayed in the bottom center of
the Traffic Map Page or in a banner at the lower left corner of other map pages
on which traffic can be displayed.
The altitude difference between the requesting aircraft and other intruder
aircraft is displayed above/below the traffic symbol in hundreds of feet. If the
other aircraft is above the requesting aircraft, the altitude separation appears
above the traffic symbol; if below, the altitude separation appears below. Altitude
trend is displayed as an up/down arrow (for speeds greater than 500 fpm in
either direction) to the right of the target symbol. Traffic symbols for aircraft
without altitude reporting capability appear without altitude separation or
climb/descent information.
