190-00709-04 Rev. AGarmin G1000 Pilot’s Guide for the Socata TBM 850327 HAZARD AVOIDANCE METARS AND TAFS NOTE: Atmospheric pressure reported for METARs is given in hectopascals (hPa), except 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 databas\ e 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. Figure 6-24 METAR Flags on the Weather Data Link Page Instructions for 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, select the METAR Softkey 2) Select the RANGE Knob and pan to the desired airport.
