METARS AND TAFS
NOTE:
Atmospheric pressure as reported for METARs is given in hectopascals (hPa), except for in the United
States, where it is reported in inches of mercury (in Hg). Temperatures are reported in Celsius.
NOTE:
METAR information is only displayed within the installed navigation database service area.
METARs (METeorological Aerodrome Reports) typically contain information about the temperature,
dewpoint, wind, precipitation, cloud cover, cloud heights, visibility, and barometric pressure at an airport or
observation station. They can also contain information on precipitation amounts, lightning, and other critical
data. METARs reflect hourly observations; non-routine updates include the code “SPECI” in the report.
METARs are shown as colored flags at airports that provide them.

Viewing METAR
and TAF Text
Selected Airport
TAFs (Terminal Aerodrome Forecasts) are weather predictions for specific airports within a 24- hour period,
and may span up to 36 hours. TAFs typically include forecast wind, visibility, weather phenomena, and sky
conditions using METAR codes.
METAR and TAF text are displayed on the Weather Information Page. METAR data is displayed first in a
decoded fashion, then as raw text. TAF information is displayed only in its raw form when it is available.
Displaying METAR and TAF text:
1)
On the Weather Data Link (XM) Page, press the
METAR
Softkey.
2)
Press the
RANGE
Knob and pan to the desired airport.
3)
Press the
ENT
Key. The Weather Information Page is shown with METAR and TAF text.
4)
Use the
FMS
Knob or the
ENT
Key to scroll through the METAR and TAF text. METAR text must be completely
scrolled through before scrolling through the TAF text.
