4.4.2 METAR
The METAR screen displays graphical Aviation Routine Weather Reports with a color
coded flag at weather reporting airports. A METAR is an hourly Aviation Routine
Weather Report from the reporting airport (not all airports have a forecast). US METARs
generally provide METAR information about the airport, date and time, wind direction
and speed, visibility, precipitation, current weather conditions, cloud cover and layer,
temperature, barometric pressure, and any other critical data. (
Figure 4-23
)
The EFD1000/500 MFD displays METARs as colored flags. The METAR screen displays
the flags, at the airport location from which the METAR is reported, overlaid on a basic
weather map. A legend is available that describes the colors of the METAR flags used.
(

METAR flags are de-cluttered according to the range selected as outlined in Table 4-4.
