3.9.1. VIEWING THE NEAREST WAYPOINTS
There are actually two waypoint scan lists for airports, VORs, NDBs, inter-
sections and user-defined waypoints. These two lists are the “complete”
list and the “nearest” list. The complete list contains all of the waypoints in
the database for a waypoint type (all the airports, for example). The near-
est list consists of the 20 nearest waypoints (of that type) to your present
position. Therefore, if you are in the nearest airport list, it will contain the
20 nearest airports relative to your location.
The nearest list is positioned in front of the complete list. That is, instead
of using the
G
button, you may also scan backwards (turn the right inner
knob counterclockwise while in the “pulled out” position) through the com-
plete list to reach the nearest list. You will know when you have reached
the nearest list because the top middle portion of the waypoint page will
flash the relative position of the waypoint to your position. “
1 ” indicates
nearest (figure 3-84) while “ 20 ” indicates the twentieth nearest (figure 3-
85). As you scan clockwise with the
right inner knob “
1 , 2 , 3 , ..., 20 ”, the
next scan position is the beginning of
the complete list. The nearest list can
only be reached by scanning back-
wards. It does not wrap around after
the last waypoint in the complete list.
Waypoint pages displayed in the nearest list do not contain a latitude and
longitude position as they do in the complete list. Instead, the bearing and
distance to the waypoint (or the radial and distance from the waypoint) are
displayed. In addition, nearest airport pages display the length, surface,
and lighting of the longest runway. Once the nearest waypoint is being
displayed, the other waypoint pages (for example, APT 2 and APT 3) for
that airport are available for display by making sure the right inner knob is
pushed in and then turning it to select the desired airport page.
The nearest list is limited to 200 NM of the aircraft’s present position for all
nearest items except for special use airspace (SUA) which is limited to
175 NM.
3.9.1.1 Nearest Airport Criteria
The 20 airports in the nearest list are the 20 airports which meet the crite-
ria selected on the Setup 4 (
SET 4 ) page. For example, you probably
wouldn’t want to take a turboprop into a 1500 foot grass strip! The SET 4
page allows you to specify what criteria you want an airport to meet before
it is considered for the nearest airport list.
