TAS/TCAS Alerts When the GTS 8XX Series 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 TA is annunciated on the display as a TA symbol or annunciation. Refer to the display pilot's guide for details. If the bearing of TA traffic cannot be determined, a yellow text banner will be displayed on the Traffic Page 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.
