HAZARD AVOIDANCE
TAS ALERTS
NOTE:
Traffic voice alerts do not occur at or below 400' AGL (if a radar altimeter is installed) or when the
landing gear is extended (if a radar altimeter is not installed). Only visual traffic annunciations are issued
under these conditions.
When the GTS 820 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 (Table 6-34). The voice alert
“
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, flashes for five seconds and
remains displayed until no TAs are detected in the area (Figure 6-172).
• The PFD Inset Map is automatically displayed with TA traffic.
If the bearing of TA traffic cannot be determined, a yellow text banner will be displayed in the center of the
Traffic Map 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.
A TA will be displayed for at least eight seconds, even if the condition(s) that initially triggered the TA are no
longer present.
