This message will remain active until all new
images are viewed.
Once images are available they are displayed
in two MFD formats. For U.S. NExRAD
radar, weather returns can be displayed on a
dedicated weather format or overlayed with
the PLAN Map format. All other images can
be displayed only on the dedicated weather
format. To overlay NExRAD on the PLAN
Map format, first choose the PLAN Map for-
mat and then press MENU on the CCP (Fig-
ure 16-118). The bottom option allows for
USA NExRAD to be turned ON or OFF. This
overlay depicts the FMS course along with
NExRAD returns to help anticipate radar re-
turns along the route of flight. The age of
NExRAD information is displayed at the
upper right portion of the PLAN map and
should update every time a new NExRAD
download is requested. Changing the range is
accomplished with the DCP range knob.
Changing the position of the map is accom-
plished using the MFD ADV key on the CDU
to advance the map to each FMS waypoint.
The dedicated weather format is chosen from
the LOWER FORMAT line select key on the
MFD by choosing the GWx selection (Figure
16-119). This format is used for NExRAD and
all other Universal weather images. The image
that appears will be the last viewed weather
image. To change the selection, press the CCP
MENU key to display the Universal weather
menu page (Figure 16-120). The menu is or-
ganized with the most recently received image
at the top. Older items may be on the next
page with up to 50 total stored images. Once
an image is past a selected effective time the
entry will turn yellow to better indicate its age.
