SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS AUDIO PANEL & CNS FLIGHT MANAGEMENT AVOIDANCE HAZARD AVOIDANCE TA ALERTING CONDITIONS The GTS 800 automatically adjusts its TA sensitivity level to reduce the likelihood of nuisance TA alerting during flight phases likely to be near airports. The system uses Level A TA sensitivity when the groundspeed is less than 120 knots; Level B TA sensitivity applies in all other conditions. Sensitivity Intruder Altitude Level Available TA Alerting Conditions Intruder closing rate provides less than 20 seconds of vertical and horizontal separation. Or: A Yes Intruder closing rate provides less than 20 seconds of horizontal separation and vertical separation is within 600 feet. Or: Intruder range is within 0.2 nm and vertical separation is within 600 feet. A No Intruder closing rate provides less than 15 seconds of separation. Intruder closing rate provides less than 30 seconds of vertical and horizontal separation. Or: B Yes Intruder closing rate provides less than 30 seconds of horizontal separation and vertical separation is within 800 feet. Or: Intruder range is within 0.55 nm and vertical separation is within 800 feet. B No Intruder range is less than 20 seconds. Table 6-28 TA Sensitivity Level and TA Alerting Criteria TAS ALERTS NOTE: Aural traffic alerts do not occur when the landing gear is extended. Only visual traffic annunciations are issued. 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 (Table 6-29). 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 (Figure 6-162). • The PFD Inset Map is automatically displayed with TA traffic.
