weather deterioration or improvement is aggregated into SkyView’s weather reporting

capability.

TAFs (Terminal Area Forecasts)

TAFs are future weather forecasts, centered on many (but not all) airports and include the

predicted future weather conditions.

Winds Aloft Forecast

The most recent winds aloft forecast from the nearest station for your airport (or the closest

within 200mn that has a forecast) is displayed in SkyView’s Airport WX Info window. The winds

and temperature aloft forecasts wind direction relative to true north, wind speed (knots), and

temperature (Celsius) for specific altitudes in feet above mean sea level.

NEXRAD Radar Imagery

NEXRAD radar transmits short high-frequency beams of radio energy into the atmosphere from

the ground at various angles and receives reflections of that energy back at the original site.

The return signal is then amplified, processed, and colorized for easy interpretation. Based on

the time it takes to receive the reflected energy, the radar data product is able to convey the

approximate location and density of precipitation at a specific location. This is then depicted

graphically on the SkyView map page.

NEXRAD radar provides high resolution local regional imagery and lower resolution imagery

that covers the entire continental US (CONUS). The FAA’s ADS-B system transmits both of these

periodically, limiting the high resolution regional weather imagery to your locale to preserve

available ADS-B data link bandwidth. SkyView presents all of this data seamlessly.

TFRs (Temporary Flight Restrictions)

SkyView can graphically depict FAA temporary flight restrictions (TFRs) that restrict GA aircraft

movement.

Weather options

Go to MAIN MENU > MAP > MAP MENU> WEATHER OPTIONS to adjust the following weather

preferences and options:

 NEXRAD – Turns the ability to display NEXRAD imagery on and off

 METAR/TAF Text – Sets whether the METAR and TAF reports that are displayed are in

their raw form, or are decoded per FAA standard abbreviations. Reports that use non-

standard codes (such as those used by military installations) will be shown in their raw

textual format.

Displaying NEXRAD Weather / TFRs

When an SV-ADSB-470 is connected and configured, MAIN MENU > MAP > LAYERS opens the

layers menu that allows you to select Terrain, or Enroute charts and weather on the map page.

You can select weather only, enroute charts or Terrain only, or depict weather on top of any of

the other layers. The terrain highlighting is displayed, but in muted tones, to allow the NEXRAD
