SV-MAP-270 Navigation Mapping Software
SkyView Pilot’s User Guide - Revision M
7-23
ZAON: A Zaon XRX.
FLARM: A device outputting FLARM format data (predominantly in Europe)
Possible states include:
SkyView is receiving traffic data from the device and there is at least one
target present.
SkyView is receiving traffic data from the device, and there are no targets
present.
There are no devices that are currently capable of providing traffic to
SkyView. This could be due to failure of traffic devices, or, if you are not in a TIS
coverage volume (TIS devices such as the SV-XPNDR-26X or GTX 330 only).
The following annunciations apply to TIS traffic devices only:
SkyView is in a TIS coverage area, but has not seen any traffic reports in the
last 6 seconds or longer.
You may see additional status information for some traffic devices. These include:
FULL: ADS-B devices only - This state signifies that the transponder is communicating
with the US-based ADS-B ground stations; that those ground stations are replying to the
SV-ADSB-470; and that your aircraft is in a known radar service volume. This allows the
ADS-B ground stations to report radar-only targets that are not yet ADS-B out equipped,
thus providing a “full” traffic picture.
PARTIAL: ADS-B, FLARM, and Zaon only: Sources that are passive traffic detectors such
as the Zaon XRX and FLARM devices are not able to directly interrogate aircraft or utilize
the ADS-B system to qualify the “completeness” of the traffic picture around your
aircraft. PARTIAL is annunciated to indicate that the traffic picture may not include the
entirety of the actual traffic environment around your aircraft. You will also see
PARTIAL when an ADS-B system is reporting that it does not know about radar traffic
targets, or when you are not receiving ADS-B ground station replies (in this case, you
may still see aircraft that are equipped with 978 MHz ADS-B out devices via the SV-
ADSB-470). This means that, although you are receiving ADS-B traffic from other ADS-B
equipped aircraft, you are not receiving non-ADS-B targets because you are not
currently in a radar service volume and/or ADS-B service volume. Therefore, the traffic
portrait may be incomplete.
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:
1.
SV-ADSB-470 with FULL traffic service: Full traffic means that you have an ADS-B ground
station reporting, and that ground station is receiving radar traffic. In this case the ADS-
