12.1.12 METARs
METAR (METeorological Aerodrome Report), known as an Aviation Routine
Weather Report, is the standard format for current weather observations.
METARs are updated hourly and are considered current. 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.
METARs are shown as colored flags at airports that provide them.
1. While viewing the Data Link Weather menu, touch the METAR
key. Touch an airport symbol for more METAR detail.
2. Touch the METAR key in the Menu again to turn it off.
