![GNS 430(A) Pilot’s Guide and Reference190-00140-00 Rev. P 12-11SECTION 12 ADDITIONAL FEATURES12.2 TRAFFIC ADVISORY SYSTEMS (TAS)IntroductionAll information in this section pertains to the display and control of the Garmin GNS 430/GTS 800 interface. NOTE: This section assumes the user has experience operating the GNS 430 and the GTS 800. NOTE: References to the GTS 800 throughout this document refer equally to the GTS 820 and GTS 850 unless otherwise noted.System DescriptionThe GNS 430 provides an optional display interface for the GTS 800 Trafc Advisory System (TAS). The GTS 800 monitors the airspace surrounding an aircraft, and advises the ight crew where to look for transponder-equipped aircraft that may pose a collision threat.Symbol Traffic Type DescriptionTraffic Advisory (TA)A TA (Traffic Advisory) is generated when the GTS 800 predicts that an intruder aircraft may pose a collision threat. A solid yellow circle represents an intruder aircraft that is on a course that projects to intercept (defined by a 0.5 nm horizontal radius and a relative altitude of ± 500 ft) the pilot’s current course within 34 seconds. A TA consists of the traffic symbol and an aural alert (e.g., “traffic, 12 o’clock, high, 3 miles”).Out-of-Range Traffic AdvisoryThis solid yellow half circle appears (on the outer range ring) under the same conditions and has the same urgency as a TA. Its appearance differs from the TA only to signify that the intruder is outside of the current range of the Traffic Page.Proximity Advisory (PA)Proximity Advisories (PA) are displayed as solid white diamonds. PAs are defined as traffic within the 6.0-nm range, within ±1200 ft. of altitude separation, and are not a traffic advisory (TA).Other Traffic SymbolThis symbol (hollow white diamond) represents traffic detected within the selected display range that does not meet the criteria for a TA or a PA and does not pose an immediate collision threat.Table 12-4 TAS SymbologyThe GTS 800 is an active trafc advisory system that operates as an aircraft-to-aircraft interrogation device. When the GTS 800 receives replies to its interrrogations, it computes the responding aircraft’s range, bearing, relative altitude, and closure rate; it then plots the traffic location and predicts collision threats.Traffic SymbologyTrafc information from the GTS 800 is displayed on the GNS 430 unit using TAS symbology (Table 12-4) on a dedicated Trafc page, and on the moving Map Page. The displayed traffic information generally includes the relative range, bearing, and altitude of intruder aircraft. The GTS 800 also generates aural announcements heard on the cockpit audio system.](https://usermanual.wiki/Garmin/0104450.Users-Manual-1/User-Guide-1159317-Page-1.png)
![GNS 430(A) Pilot’s Guide and Reference 190-00140-00 Rev. P12-12SECTION 12 ADDITIONAL FEATURESAltitude deviation (Figure 12-20) from own aircraft altitude is displayed (in hundreds of feet) for each target symbol. If traffic is above own aircraft altitude the deviation is shown above the target next to a ‘+’ symbol. If traffic is below own aircraft altitude the deviation is shown below the target next to a ‘-’ symbol.Altitude trend (Figure 12-20) is displayed as an up arrow (> +500 fpm), down arrow (< -500 fpm), or no symbol if less than 500 fpm rate in either direction.Figure 12-20 Traffic Symbol ComponentsAltitudeDeviation Altitude Trend Traffic TypeAural AlertsA TA consists of a displayed trafc symbol (solid yellow circle) and an aural alert. The aural alert announces “traffic”, followed by the intruder aircraft’s position, altitude relative to own aircraft (“high”, “low”, or “same altitude”), and distance from own aircraft; e.g. “trafc, 12 o’clock, high, 3 miles”.Power-up Self-TestCheck for the following test criteria on the Trafc Page during power-up:• If the GTS 800 passes the power-up test; and the aircraft both has a squat switch and is on the ground, the Standby Screen is displayed (Figure 12-21).• If the GTS 800 passes the power-up test and the aircraft both has a squat switch and is airborne, the Trafc Page is displayed on the 6-nm display range and in the normal altitude display mode.• If the GTS 800 passes the power-up test and the aircraft does not have a squat switch, the Standby Screen is displayed (Figure 12-21).• If the GTS 800 fails the power-up test (as indicated by a FAILED screen), the GTS 800 is inoperable, see the GTS 800 Installation Manual for detailed information on Failure Response.Figure 12-21 Standby Mode NOTE: When the system is in standby, the GTS 800 does not transmit, interrogate, or track intruder aircraft.](https://usermanual.wiki/Garmin/0104450.Users-Manual-1/User-Guide-1159317-Page-2.png)
![GNS 430(A) Pilot’s Guide and Reference190-00140-00 Rev. P 12-13SECTION 12 ADDITIONAL FEATURESTracking intruder aircraft1) Press the small right knob to activate the cursor and highlight ‘STBY’.2) Turn the small right knob to select ‘OPER’.3) Press the ENT Key to confirm operating mode and begin tracking intruder aircraft. NOTE: The FAILED message is displayed when the system detects an error that prohibits further traffic display operation.User-initiated TestIn addition to the power-up test, the GTS 800 performs self-tests during normal operation. A self-test is performed once per minute to verify that the antenna is connected. Also, a calibration is performed at varying intervals based on time and temperature. A user-initiated test of the GTS 800 interface can also be performed. NOTE: A user-initiated test can only be performed when in standby or failed mode.Performing a user-initiated test:1) Turn the small right knob to select the Traffic Page.2) From the Traffic Page, press the MENU Key to display the Page Menu.3) Turn the small right knob to select ‘Self Test?’.4) Press the ENT Key.Switching Between Standby and Operating ModesThe unit must be in operating mode for traffic to be displayed. The ability to switch out of standby into operating mode on the ground is especially useful for scanning the airspace around the airport before takeoff. Operating Mode is conrmed by the display of ‘OPER’ in the upper right-hand corner of the Trafc Page (Figure 12-22).Switching to Operating Mode from Standby Mode:1) Press the small right knob to activate the cursor and highlight ‘STBY’.2) Turn the small right knob to select ‘OPER?’.3) Press the ENT Key to confirm and place the GTS 800 in operating mode, the GTS 800 switches out of standby into the 6-nm display range. NOTE: If the aircraft has a squat switch and the pilot does not manually switch out of standby, the GTS 800 will automatically switch out of standby 8 to 10 seconds after takeoff.Switching to Standby Mode from the Traffic Page:1) Press the small right knob to activate the cursor and highlight ‘OPER’.2) Turn the small right knob to select ‘STBY?’.3) Press the ENT Key to confirm and place the GTS 800 in standby mode. NOTE: If the aircraft has a squat switch, STBY is not displayed while the aircraft is airborne but will go into standby 24 seconds after landing. This delay allows the GTS 800 to remain out of standby during a touch-and-go maneuver.](https://usermanual.wiki/Garmin/0104450.Users-Manual-1/User-Guide-1159317-Page-3.png)
