wards the destination, from the start, then the line stays in the center. If
you drift off course to the right, the line moves to the left . This signifies that
you need to steer to the left to get back on course. This is called "chasing
the needle". If you steer towards the line (needle), you'll always be head-
ing in the correct direction to get back on course.
The CDI's range shows beneath the CDI label. On the
screen at right, the CDI range is .20 mile, which is the
default. You can adjust the range by selecting the
"ALARMS/CDI" label on the main menu. This is also
shown by the dotted lines at the far left and right side of
the CDI. If the solid line is on either of the dotted lines,
then you are 0.20 mile off course. Remember, if the
line moves to the left, then you are too far to the right of
the desired course line and vice-versa.
Using the CDI with a mapping screen helps you visu-
alize your position in relation to the course. The map
screen on the right shows that we are off course to the
right. The vertical bar on the CDI shown above has
moved to the left side, showing the direction to the de-
sired course line. The CDI gives you a quick, easy to
read visual indicator of your relationship between your
direction of travel and the desired direction.

Map

The AirMap 100 has a ground map of the world built inside. This map has
the majority of its detail in far southern Canada, the continental United
States and Hawaiian islands, northern Mexico, the Bahamas, and Ber-
muda. The map screens show your course and track from a "birds-eye"
view. If you're navigating to a waypoint, the map shows your starting loca-
tion, present position, course line, and destination. You don't have to navi-
gate to a waypoint, however, to use the map.
A complete aviation database is included using Jeppe-
®
sen data . Airports, NDBs, VORs, and other airspace
information (including obstructions such as radio and
TV towers) are overlaid onto the ground map.
Using the map is as simple as pressing the PAGES
key, then highlighting "MAP 1". A screen similar to the
one at right appears. The airplane symbol in the center
of the screen is your present position. It points in the
direction you're travelling. The solid line extending from
