SUA alert messages for class B, class C, MOAs,
restricted and other areas may be turned off to avoid
nuisance alerts, and may also be removed from the map
to avoid excess clutter at higher map scales. For com-
plete information and definitions on SUAs, see page 52.
The GPS 90’s nearest function will also provide you
with a list of the nine nearest airports, VORs, NDBs,
intersections and user waypoints to your present posi-
tion. The internal Jeppesen database used in the GPS 90
contains information about thousands of waypoints,
which are divided into specific categories for your con-
venience. For more on waypoint categories and the
internal database, please see page 17-27 after completing
the takeoff tour.
To view the nearest waypoints of a particular category
(airports, VORs, NDBs, intersections or user waypoints),
you need to select the desired category from the category
field at the top of the nearest page. Let’s practice by
viewing the nearest airports to our present position:
1. Press the
G
key twice to display the nearest page.
2. Press
E
to begin selection of the desired category.
3. Press the
D
key repeatedly to scroll through the waypoint
categories until ‘APT’ appears in the category field.
4. Press
E
to confirm the category. The field highlight will
move to the first facility on the list.
Once you’ve selected and confirmed a category, the
GPS 90 will display the nine nearest facilities and pro-
vide the distance and bearing to each waypoint in the
list. To scroll and review the nearest waypoints list:
1. Press the
D
key to highlight to the desired waypoint.
2. Press
E
to review the waypoint page(s).
3. Press
E
again to return to the nearest list. The field
highlight will sequence to the next waypoint on the list.
4. Press
Q
to exit the nearest function and return to the
previously viewed page.
