Metar
S anD
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, dewpoint, 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. TAF information is only available from the Waypoint
Page.
METAR data is displayed on the Map Page and the Weather (WX) Page. An
abbreviated version can be viewed by touching the METAR flag. Touching the identifier
name displays additional information.
The METAR flag color is determined by the information in the METAR text.
VFR (ceiling greater than 3000 feet AGL and visibility greater than 5
miles)

IFR (ceiling 500 to below 1000 feet AGL and/or visibility 1 mile to less
than 3 miles)
Low IFR (ceiling below 500 feet AGL or visibility less than 1 mile)
