TIS-B traffic information includes non-participating aircraft detected by ATC
surveillance radar. As TIS-B data is derived from ATC surveillance radar data, TIS-B
traffic position updates typically occur every three to thirteen seconds. Therefore,
TIS-B traffic may be displayed with degraded positional accuracy. Aircraft
without operating transponders are invisible to TIS-B. Aircraft operating
outside of the ATC radar coverage area are also not displayed.
Since the GDL 39 is a receive-only device, even when used onboard an aircraft
equipped with a qualifying GPS and 1090 ES transponder, a GBT may not identify it as
an ADS-B participating aircraft. The squitter of some 1090 ES transponders, including
the Garmin GTX 23ES, must be configured to communicate that the aircraft has 978
MHz receive capability in order to be identified as an ADS-B participating aircraft.
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 within range of the aircraft. Due to lack of equipment, poor signal
reception, and/or inaccurate information from aircraft or ground stations, traffic may be
present that is not represented on the display.

SYSTEM STATUS

The traffic system status is annunciated in the upper left corner of the Map Page,
as well as the lower left corner of the dedicated Traffic Page.
Full traffic services available for an ADS-B participating
aircraft (ground linked TIS-B, FIS-B and ADS-R, and Air-
to-Air ADS-B). If you are using the GDL 39 on a non-
participating aircraft you may still see this when you
are within the service area of a participating aircraft.
As a non-participating aircraft you are only receiving
TIS-B traffic information for traffic within 15 nm and
3,500' of the participating aircraft
