GRAPHICAL METAR
The graphical METAR is
derived from the most cur-
rently received textual
METAR or SPECI data from
reporting sites. This is dis-
played on a map back-
ground to enhance situa-
tional awareness as shown
on Figure 20.
The graphical METAR icon
is gray when the textual
METAR or SPECI report
exceeds 75 minutes (AGED),
but is less than the textual METAR expiration time of 120 minutes.
Look at the textual report for ceiling and visibillty information.
CAUTION: Graphical METAR data must be used for strategic plan-
ning purposes only. Due to inherent delays, areas of coverage
and relative age and availability of the data that can be experi-
enced, Graphical METAR data cannot be viewed as an absolute
depiction of conditions at a specific location.
Graphical METARs are shown using two color coded boxes, one indi-
cating ceiling (upper box), the other visibility (lower box). Next to the
boxes is the ICAO station identifier for the airport to which the METAR
pertains. Color coding for the boxes is specified in the table below:
Moving the joystick pointer to an area that will not highlight a specific
report then pressing the MORE INFO softkey will display the graphical
METAR legend as shown in Figure 21.
