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 col-
lision 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.
