7.20 Map Page
7.20.1 Configuration
The moving map and weather pages are capable of displaying a large quantity
and variety of data. Map data is layered to ensure that data which is typically
more critical is drawn above less critical data, however at some zoom scales and
configurations the map may be cluttered with large amounts of data. Controls
are provided on the Map and Weather pages for the pilot to select which data
displayed, the declutter level, and the zoom scales at which data is added to or
removed from the display. It is the responsibility of the pilot to select settings
for the map page that will provide the display of data most appropriate to the
operation being conducted.
7.20.2 Flight Plan Depiction
The map page depicts the current active flight plan. When an off-route Direct
To is active the flight plan will no longer be depicted on the map.
7.20.3 Fuel Range Ring
The distance between the segmented green reserve ring and the yellow zero fuel
ring is 45 minutes at the current aircraft groundspeed by default. The pilot may
change the fuel reserve time value on the map setup menu. Changes to the fuel
reserve time are persisted over GTN power cycles.
Visibility of the fuel range ring may be affected by the underlying map data
selectable by the pilot. The pilot may make changes to the topographic or terrain
data in order or more clearly observe the fuel range ring at any time.
Fuel range data is derived from the interfaced fuel totalizer data. Data entered in
the Fuel Planning pages will not update the fuel range ring.
7.21 User Defined Waypoints
When a User Defined Waypoint is created a default name will automatically be
provided and the pilot is given the option to provide a different name for the
waypoint. Pages which have the autofill function will prevent some waypoint
names from being used. If it is desired to name the waypoint with a subset of
the name of an existing waypoint in the database then this must be accomplished
on the Waypoint Info / User Waypoints page.
Waypoints which are created when a Search and Rescue pattern is created are
not considered User Waypoints and therefore functions associated with User
Waypoints are not provided for these waypoints.
7.22 Times and Distances
Time and Distance data to the next waypoint is always calculated from the
present position to that waypoint and does not account for the path which may
be flown (such as intercepting a course) to reach the waypoint.
