Use the Clear OBS Hold command to resume navigation. The HSI Navigation
displays will point to your original destination again. At right, you can see the
pilot's diversion in his trail on the map page.
You can turn off OBS Hold at any time using the HSI Page menu. Press
MENU| to CLEAR OBS HOLD|ENT. The navigation data will once again
direct you to your destination, or the next waypoint in the route you're
navigating. Beginning navigation to a new destination will automatically
clear OBS Hold, as well.
Map Page
The map screens (including the Airport Orientation Page) show your
course and track from a "bird's-eye" view. By default, this unit shows
the Map Page map with north always at the top of the screen. (This can
be changed using options described in the topic Map Orientation, in
Sec. 5.) If you're navigating to a waypoint, the map also shows your
starting location, present position, course line and destination.
NOTE:
When our text says "navigating to a waypoint," we really mean navi-
gation to any selected item, whether it is a waypoint you made, a
map feature or an item (like a VOR) from the Jeppesen database.
Using the map is as simple as pressing the
PAGES key. A screen similar
to those in the following images appears. The aircraft in the center of
the screen is your present position. It points in the direction you're
traveling. A solid line extending from the plane's tail is your plot trail,
or path you've taken. (Remember, a flashing question mark on you
plane symbol or flashing text displays means AirMap has not yet cal-
culated a position.)
The map zoom range is the distance across the screen. This number
shows in the lower left corner of the screen. In the first example below
left, the range is 4,000 nautical miles from the left edge of the map to
the right edge of the map.
