The bottom left softkey is the Zoom-In softkey; the second softkey
from the left is the Zoom-Out softkey. These two softkeys are active
without pressing the E key. Each time you depress one of these
softkeys, you scale by one-half or by double the graphical area. If you
look to the top ofthe screen, just right ofthepage number (PLOT 1 or
PLOT 2), you will see a number in a white square. This is the scale of
the graphic window based on the units selected in CFGl Navigation .
Now look along the left and right edge ofthe graphic window, you will
see some vertical black and white dash marks (these are harder to see
at small scales like I and 2 or at large values such as 64 or 128). Each
solid dash mark represents I nautical mile. A broken dash mark indi-
cates I /l OOth of a nautical mile when you are zoomed in at low scale.
You will find your bearing and range to the next waypoint (PLOTl) or
marker position (pWTI) just below the page number. The PLOT2
screen also provides the marker coordinates and the datum currently
in use (set in CFGl Datum).
The
CFGl
Navigation menu allows you to display fractions of the
major unit (nautical miles, statute miles, or kilometers) ranges less than
1000 in alternate units of feet or meters.
