Hazard Avoidance
A Proximity Advisory (PA), displayed as a solid white diamond or triangle, indicates
the intruding aircraft is within ±1200 feet and is within a 6 nm range, but is still not
considered a TA threat.
A Non-threat Advisory, shown as an open white diamond or triangle, is displayed for
traffic beyond 6 nm that is neither a TA or PA.
Relative altitude, when available, is displayed above or below the corresponding
intruder symbol in hundreds of feet. When this altitude is above own aircraft, it is
preceded by a '+' symbol; a minus sign '-' indicates traffic is below own aircraft.
A vertical trend arrow to the right of the intruder symbol indicates climbing or
descending traffic with an upward or downward-pointing arrow respectively.
Flight IDs may also be displayed with traffic symbols; see the Flight IDs discussion in
this section for more information.
TAS ALERTS
When the GTS 800 detects a new TA, the following occur:
• A single "Traffic!" voice alert is generated, followed by additional voice information
about the bearing, relative altitude, and approximate distance from the intruder that
triggered the TA. The announcement "Traffic! 12 o'clock, high, four miles," would
indicate the traffic is in front of own aircraft, above own altitude, and approximately
four nautical miles away.
• A TRAFFIC Annunciation appears at the top right of the airspeed on the PFD, flashing
for five seconds and remains displayed until no TAs are detected in the area.
If the bearing of TA traffic cannot be determined, a yellow text banner will be
displayed in the center of the Traffic Page and in the lower-left of the PFD inset map
instead of a TA symbol. The text will indicate "TA" followed by the distance, relative
altitude, and vertical trend arrow for the TA traffic, if known.
