MAP 1 MAP 2 MAP 3
There are three different mapping screens available. Map screen number
3 shows by default, as shown at right. Your current position displays at the
center of the screen by a cross surrounded by a flashing diamond.
To view the other mapping screens, press the PAGES key. Press the up
or down arrow key to highlight the "MAP 1" label. Now press the right or
left arrow key to select a different mapping screen. Press the EXIT key to
erase the pages menu.
Maps 2 and 3 (as shown above) have navigation data displayed using
digital numbers. The digital displays on map 3 can be rearranged or
changed to other displays. See the “Reprogram Boxes” section for more
information.
As you move, the map slides past your present
position, which always remains at the center
of the screen. The line extending from your
position shows the path you’ve taken.
Use the Z-OUT and Z-IN keys to enlarge or
reduce the mapping area. If you have an IMS
SmartMap™ cartridge installed, it’s detail typi-
cally begins showing when you zoom in to the
10 mile range.
Jeppesen™ data shows at all zoom ranges, however, Lowrance
®
has a
unique method of displaying this data. If you were to turn on all airports,
VORs, NDBs, and controlled airspaces at the same time without filtering
the data, the map screen would become so cluttered that it would be
useless. The AirMap turns off virtually all aviation data at large ranges,
selectively turning on more data as you zoom in closer to your present
position or cursor location. See the two screens at the top of the next
page. The first one’s range is 150 NM and shows little aviation data. The
second screen is zoomed in to the 30 NM range and now shows much
more detail around the present position.
