ADS-B Data Service
When connected to an SV-ADSB module, The EFIS can display NEXRAD weather and Temporary flight
Restriction (TFR) information visually on the map or sectional page. Additionally, textual METAR and TAF
weather reports are available for airports that report such information. The SV-ADSB receives traffic and
weather via the 978 MHz UAT ADS-
B frequencies, which are only utilized by the FAA’s ADS-B system.
Therefore, traffic and weather are only available in the US (and other places the FAA may have ADS-B
ground stations, including Guam, Puerto Rico, and the US Virgin Islands). The SV-ADSB will not work
outside these areas.
Weather information is transmitted continuously over a data link from the ground, but reception of weather
data is dependent on ADS-B ground station proximity/coverage, signal strength, and other environmental
conditions. Therefore, ADS-B weather reception may not be continuous.
Due to latencies that accumulate while NEXRAD weather images are created, and the way that the FIS-
B/NEXRAD services timestamp weather data, NEXRAD images are actually ALWAYS older than the age
indicated on the display. In extreme cases, this can mean that the images you see on the map may be 15-20
minutes older than the age indicated. See http://www.ntsb.gov/doclib/safetyalerts/SA_017.pdf for further
information about this phenomenon.
Never rely on NEXRAD imagery to try to “squeeze” through a weather system. Often, deadly turbulence and
wind shear are present, even in places in storm systems where there is no precipitation indicated.
The Weather and TFR information that the EFIS provides is supplemental information only. It should not be
used as your primary means of weather information. Only official FAA briefing information sources should be
used to make critical aeronautical weather decisions.

NEXRAD Data Coverage
In some circumstances, geographic areas may not have NEXRAD imagery available. This may be the
case if:
•
Data is not available for the area because there is no NEXRAD coverage in the locale. This can
be observed in the areas surrounding the US in Figure 152 above.
•
Data blocks not received for an area due to radio signal obscuration, interference, or other
radio phenomena:
Data has not yet been received for an area for which there is available coverage, due to the time it
takes for the ADS-B system to transmit information.
Areas for which no data is available will depicted with a darker background.
