GRIB routing
9.21
Checking Overlay allows you to view the wind forecast over the top of
a chart, as shown in Figure 9.15. When this is on, figures showing the
direction and strength of the wind at the position of the cursor will be
shown in the Status bar.
Note. If you wish to view the overlay without the Edit GRIBs window,
click outside the window. If you close the window, the GRIB overlay
will no longer be displayed.
However, to make changes in setup plan the Edit GRIBs window must
be closed first.
Note. To change the type of wind arrows used to represent the wind, you
must enter the Animation mode and select an arrow style – see page
3.19.
