The enroute map provides the required information for enroute navigation. The enroute map lets you see all regions of the earth, including the North and South Pole. There are three map
CTR Track Up
CTR North Up
The ribbon tile located on the right hand side provides several options to control the display and functionality of the map:
Scale - controls the width of the map displayed in nautical miles (NM).
AWY (Airway) - controls whether to display high or low airways and related information on the enroute map.
COM (Communication) - controls the display of radio communication frequencies.
ERA (Enroute Alternate) - controls the display of aerodromes in your terminal chart library that may serve as enroute alternatives.
■ Map - three possible options PAN, CTR North Up and CTR Track Up.
Let's have a look at these in more detail.
Here is the ribbon tile located on the right hand side of the map. We shall now go through each of the tiles in more detail.
Click the Scale menu item.
The scale controls the width of the map displayed in nautical miles (NM). The widths assigned to the OCEANIC, WIDE, NORM and NARROW options are by default set to 300NM (OCEANIC), 150NM (WIDE), 75NM (NORM) and 50NM (NARROW)., however, your system administrator may define custom zoom levels. If you pinch zoom or use your mouse wheel to zoom in or out it will change to CUSTOM with the relevant distance in NM showing, as it is currently showing custom 642NM. We will zoom into NORM 75NM.
Click the NORM 75NM list item.
The map has now zoomed in to NORM 75NM as shown in the ribbon tile.
Currently we are viewing low airways on the map these are indicated on the map as cyan color
High airways are displayed in black in day mode and white in night mode while low airways are displayed in cyan in both day and night mode.
Let's change the airway to high.

Click the ERA menu item.
When ERA goes to POS mode this will indicate all the aerodromes that are part of your terminal chart library in the following dedicated color.
When in ERA is set to POS, tapping an aerodrome that is contained in your terminal chart library will ask you whether you want to add the aerodrome to your ALTN chart screen.
