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.

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.

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.
