SkyView HDX Pilot’s User Guide – Revision B 5-27
o An ADS-B system is reporting that it does not know about radar
traffic targets, or that it is not receiving information from any ADS-B ground
station (in this case, you may still see aircraft that are equipped with 978 MHz
ADS-B out devices via the ADS-B receiver). Although you are receiving ADS-B
traffic from other ADS-B equipped aircraft, you are not receiving all detectable
traffic because you are not currently in a radar service volume and ADS-B service
volume. Thus, the traffic portrait may be incomplete.
• TIS: Traffic provided from an SV-XPNDR-261/262, Garmin GTX 330, or any other device
that is configured to output traffic information in the Garmin TIS format.
o SkyView is receiving traffic data from the device which is
providing traffic to the best of its ability.
o SkyView is connected to a TIS traffic device, but you are not in
a TIS service volume (actual TIS devices such as the SV-XPNDR-261/262 or GTX
330 only).
• ZAON: A Zaon XRX.
o SkyView is receiving traffic data from the device which is
providing traffic to the best of its ability.
• FLARM: A device outputting FLARM format data (predominantly in Europe)
o SkyView is receiving traffic data from the device which is
providing traffic to the best of its ability.
• SkyView is configured for Traffic but there are no devices that are
currently capable of providing traffic to SkyView. This could be due to failure of traffic
devices, or an external device that is turned off.
Traffic Receiver Priority
Only one device can provide traffic information to SkyView at any moment. If you have more
than one device capable of providing traffic, these traffic sources are priority ordered based on
the completeness of the traffic portrait they provide:
3. SV-ADSB-470/472 with a full traffic portrait (ADS-B OK): Means that you have an ADS-B
ground station reporting, and that ground station is receiving radar traffic. This is only
possible if you are equipped with an ADS-B Out device such as a SV-XPNDR-261/262 or
Garmin GTX 330 ES transponder. In this case the ADS-B system delivers all known ADS-
B equipped traffic and all radar targets that FAA radar system can see.
