Information/Traffic Data Receiver
The page Traffic Data Receiver provides status information on the data connection between Enroute Flight Navigation and your traffic data receiver. To access the page, open the main menu and choose “Information/Traffic Data Receiver.”
Connection Status
To ensure reliable operation, traffic receivers emit “heartbeat messages” at frequent intervals. The text field “Connection Status” shows if heartbeat messages are received through any of the configured data channels. If yes, this field shows the data connection currently used and lists the types of data presently received.
Traffic Data Receiver Status
If heartbeat messages are received, this field shows status messages reported by the traffic data receiver, including results of internal self-tests of the traffic data receiver hardware. If no heartbeat messages are received, this field is invisible.
Position
If your traffic data receiver provides its own SatNavS position, this field shows the position reported by the traffic data receiver. If no heartbeat messages are received, or if the traffic data receiver does not provide its own SatNav position, this field is invisible.
True Altitude
If your traffic data receiver provides its own altitude information, this field shows the true altitude reported by the traffic data receiver. Otherwise, this field is invisible.
True altitude AGL or AMSL is the vertical distance from the aircraft to the terrain or to the main sea level, respectively.
Warning
True altitude is not the same as barometric altitude, which is the altitude shown on your aircraft’s altimeter. Depending on weather conditions, true altitude and barometric altitude may differ substantially. Never use true altitude to judge the vertical distance from your aircraft to an airspace boundary.
Pressure Altitude
If your traffic data receiver provides its own pressure altitude information, this field shows the pressure altitude reported by the traffic data receiver. Otherwise, this field is invisible.
Pressure altitude is the altitude in the standard atmosphere at which the pressure is equal to the current atmospheric pressure. This is the altitude displayed on the aircraft’s altimeter when set to the standard pressure of 1013.2hPa. This is also the altitude shown on the transponder.
Traffic
If heartbeat messages are received, this field lists all the traffic reported by the traffic data receiver, sorted in order of importance. If no heartbeat messages are received, this field is not shown.
Traffic opponents are classified as “Relevant Traffic” and “Irrelevant Traffic”. Traffic is considered relevant if the vertical distance to the traffic opponent is less than 1,500 m and the horizontal distance is less than 20 NM. Only relevant traffic is shown in the moving map.
Help
If no heartbeat is received from any traffic receiver, two buttons “Connect to a traffic receiver” and “Connect to a flight simulator” will become visible. A click on any of these buttons will open the appropriate page of the manual.
