o This signifies that the transponder is communicating with the
US-based ADS-B ground stations; that those ground stations are replying to the
ADS-B Receiver; and that your aircraft is in a known radar service volume. This
allows the ADS-B ground stations to report all ADS-B targets and radar-only
targets that are not yet ADS-B out equipped, thus providing a full traffic picture.
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. Therefore, the traffic portrait may be incomplete.

TIS: Traffic provided from an SV-XPNDR-26X, 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-26X 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 that is capable of providing traffic, these traffic sources are priority ordered
based on the completeness of the traffic portrait they provide:
