SECTION 11 ADDITIONAL FEATURES Switching Between Standby and Operating Modes The 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 confirmed by the display of 'OPER' in the upper righthand corner of the Traffic Page (Figure 11-23). 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 8XX in operating mode, the GTS 8XX switches out of standby into the 6-nm display range. Traffic Page Traffic can be displayed both on the Map Page (only if heading is available) and on the Traffic Page (Figure 11-23). The orientation source shown at the top of the display first uses heading ('HDG'), then GPS Track ('TRK') if no heading is available, to orient the display. If the GTS 8XX does not have bearing information for an active TA, 'TA' followed by range, relative altitude, and altitude trend is displayed in the lower right corner. The Traffic Banner is displayed if more than one TA with no bearing info is active, while the TA of most immediate threat is displayed in text below the banner. Display Range Traffic Orientation Source Operating Mode Traffic Banner NOTE: The GTS 8XX will automatically switch out of standby 8 to 10 seconds after takeoff, which is determined by ground speed or by a transition of the aircraft squat switch (if connected). 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 8XX in standby mode. NOTE: The GTS 8XX goes into standby mode 24 seconds after landing, which is determined by ground speed or by a transition of the aircraft squat switch (if connected). This delay allows the GTS 8XX to remain out of standby during a touch-and-go maneuver.
