AutoZoom
AutoZoom automatically changes the map scale to
keep your present position and destination on the display
at all times. Whenever a GOTO or route is activated,
AutoZoom will default to the largest map scale that will
fit your present position and ‘active to’ waypoint (up to
the 50 nm scale). As you head toward the destination, the
scale will change to the next lower scale when your pre-
sent position and the destination can be displayed on that
particular scale.
The AutoZoom feature will stop when the scale has
reached the 1.2 nm setting. AutoZoom is designed to
allow you to manually change the map scale without
turning the automatic map scaling off. In addition,
AutoZoom determines whether or not to change the scale
based upon the current status of the map:
•If the map scale is manually zoomed in before an
AutoZoom takes place, the automatic scaling will
resume once it reaches the scale you have selected.
• If the map scale is manually changed to a setting
higher than the current AutoZoom setting, auto-
matic map scaling will be cancelled unless the map
scale is manually returned to the current or smaller
AutoZoom setting.
• If the zoom field is active (it has been highlighted
and the
E
.
key has been pressed) when the map
is ready to scale down to the next level, the
AutoZoom feature will be cancelled.
The AutoZoom feature can be turned off through the
map option menu described on page 44.
Waypoint Category Viewing Scale
The map options menu’s ‘WAYPOINTS’ selection
allows you to define what waypoint types and text are
displayed on the map and the scales in which they will
appear. The categories on the setup page are: APT, INT,
NDB, VOR, User and Ident(ifier). The scale field to the
right of each category lets you designate a maximum map
scale at which the item will appear or allow you to turn
the category off altogether. Each category has 19
adjustable settings, from 0.2 nm to 500 nm and ‘OFF’.
