Garmin 496 Manuale Proprietario

The GPSMAP 496 supports TIS input from a Garmin Mode S 

transponder, such as the GTX 330. 

1.  Press 

MENU twice. The Main Menu appears.

2.  Highlight the 

Setup tab.

3.  Use the 

ROCKER to select the Interface sub tab.

4.  Highlight the 

Serial Data Format field, and use the ROCKER 

to select 

TIS In. 

The status field indicates one of the following messages:

•  Waiting For Data—searching for a valid TIS data stream. 

•  Data Available—receiving TIS data from the transponder.

•  Data Unavailable—connection to transponder established, 

but TIS service is unavailable.

•  Lost Connection—an error occurred or the connection to the 

transponder was lost.

TIS traffic is shown on the GPSMAP 496 according to TCAS 

symbology, graphically shown on an alert window, and on the 

moving Map Page. A Traffic Advisory (TA) symbol appears as a 

solid yellow circle. All other traffic is shown as a hollow white 

diamond. Altitude deviation from own aircraft altitude is shown 

above the target symbol if traffic is above own aircraft altitude, and 

below the symbol if they are below own aircraft altitude.  Altitude 

trend is shown as an up arrow (>+500 ft/min), down arrow (<-500 

ft/min), or no symbol if less than 500 ft/min rate in either direction. 

A TIS audio alert is generated whenever the number of Traffic 

Advisories on the GPSMAP 496 screen increases from one scan to 

the next. Limiting Traffic Advisories only reduces the “nuisance” 

alerting due to proximate aircraft. For example, when the first Traffic 

Advisories appear on the TIS display, the user is alerted audibly. 

So long as a single aircraft remains on the TIS display, no further 

audio alert is generated. If a second (or more) aircraft appears on the 

screen, a new audio alert is sounded.
