SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS AUDIO & CNS FLIGHT MANAGEMENT 6.7 GTS 800 Traffic Hazard Avoidance WARNING: Do not rely solely upon the display of traffic information for collision avoidance maneuvering. The traffic display does not provide collision avoidance resolution advisories and does not under any circumstances or conditions relieve the pilot's responsibility to see and avoid other aircraft. WARNING: Do not rely solely upon the display of traffic information to accurately depict all of the traffic information within range of the aircraft. Due to lack of equipment, poor signal reception, and/or inaccurate information from other aircraft, traffic may be present but not represented on the display. The Garmin GTS 800 is a Traffic Advisory System (TAS). It enhances situational awareness by monitoring the airspace for transponder-equipped aircraft. The system also provides visual annunciations and voice alerts to assist the pilot with visual acquisition of traffic. The system can display a maximum of 30 aircraft with the highest threat potential simultaneously. The system provides no surveillance information for aircraft without operating transponders, or if the system does not receive this transponder information for any reason. Theory of operation When the system is in Operating Mode, the traffic system interrogates the transponders of other aircraft in the vicinity while monitoring for transponder replies. The system uses this information to derive the distance, relative bearing, and if reported, the altitude and vertical trend for each aircraft within its surveillance range. The system then calculates a closure rate to each intruder based on the projected Closest Point of Approach (CPA). If the closure rate meets the threat criteria for a Traffic Advisory (TA), the system provides a visual annunciation with voice alerting. TAS surveillance VOLUME and Symbology The GTS 800 TAS monitors the airspace within ±10,000 feet of own altitude, and up to 22 nm in the forward direction. Range is somewhat reduced to the sides and aft of own aircraft due to the directional interrogation signal patterns. The system displays TAS-detected traffic using the symbology shown in Table 6-21. In addition, if a 1090 MHz Extended Squitter transponder is installed, and the GTS 800 detects airborne traffic providing 1090 MHz Automatic Dependent Surveillance - Broadcast (ADS-B) information, the system will display the TAS-detected traffic using the ADS-B symbology shown in Table 6-22. NOTE: Do not confuse this functionality with full ADS-B capability, which can provide traffic information from ADS-B Ground-Based Transceivers (GBTs) and ADS-B traffic outside of the TAS surveillance volume. This system is limited to displaying ADS-B information from suitably equipped airborne aircraft within the TAS surveillance volume.
