NOTE:
METAR information is only displayed within the installed aviation
database service area.
METAR (METeorological Aerodrome Report) is an international code used for
reporting weather observations. METARs are updated hourly or as needed. METARs
typically contain information about the temperature, dew point, wind, precipitation,
cloud cover, cloud heights, visibility, and barometric pressure. They can also contain
information on precipitation amounts, lightning, and other critical data. If METAR data
is available for an airport, a color-coded flag is shown next to the airport.
TAF (Terminal Area Forecast) is the standard format for 24-hour weather forecasts.
TAFs may contain some of the same code as METAR data. It typically forecasts
significant weather changes, temporary changes, probable changes, and expected
changes in weather conditions.
METAR and TAF text data is displayed on the Map Page and the Weather (WX) Page.
An abbreviated version can be viewed by panning over the METAR flag. Pressing the
ENT
Key will display additional information. METAR and TAF data can be displayed as
raw or decoded text.

1)
Using the Map Pointer, select the desired METAR and press the
ENT
Key; or
from the Waypoint (WPT) Page press the
