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. These only apply when the weather layer is turned on:

Metar Icons – Turns the ability to depict airports as color-coded Metar icons on or off.

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 depict weather on top of any of the other layers. The terrain
highlighting is always displayed, but in muted tones, to allow the NEXRAD weather / TFR
