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. Traffic TIS also provides a vector line showing the direction in which the traffic Terrain is moving, to the nearest 45°. Traffic information for which TIS is unable to determine the bearing (non-bearing traffic) is displayed in the center of the Weather Traffic Page or in a banner on maps other than the Traffic Map Page on which traffic can be displayed.

Altitude trend is displayed as an up/down arrow (for speeds greater than System 500 fpm in either direction) to the right of the target symbol. Traffic symbols for aircraft without altitude reporting capability appear without altitude separation Messages or climb/descent information.
