2 Detailed Explanation
Adjusting the Map
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 modes:
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).
AIRSPACE - 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, NORTH UP and TRK UP.
Let's have a look at these in more detail.
The ribbon tile is located on the right hand side of the map. Let's have a look at each tile in more detail.
The scale controls the width of the map displayed in nautical miles (NM). The widths assigned are OCEANIC and CUSTOM, however your system administrator may define custom zoom levels. If you pinch zoom or use your mouse wheel to zoom in and out it will change to custom with relevant distance in NM showing, as it is currently showing CUSTOM 269NM. Clicking the scale button will zoom you out to 3000NM and OCEANIC.
Click the Scale button.
Currently we are viewing low airways on the map these are indicated on the map as teal
High airways are displayed in black in day mode and white in night mode while low airways are displayed in teal in both day and night mode.
Let's change the airway to high.
Click the Airspace button.
You can now see that the airways have changed to white. When selecting AWY HIGH, only information that relates to the high level airways structure is displayed, including Waypoints, Navaids, Special Use Airspace, Holdings and Control Area information.
Let's have a look at the communications feature on the ribbon tile.
Click the COM menu item.
You can see that the communication features controls the display of radio communication frequencies box in the bottom right corner. Frequencies shown are those applicable to the center of the Enroute display, indicated by the cross hair symbol in the center of the screen.
ERA (enroute alternate) From 19.1 version, all ADs that in your subscription are always displayed in teal color. ERA button is only used to display 4 closest ADs currently available in your subscription that may serve as an Enroute alternates.
With ERA in the OFF mode, the 4 closest ADs are hidden.
When in ERA is set to REL or OFF, 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.
The map is currently set to PAN mode, allowing you to move freely around the map. Let's have a look at changing this option.
Click the Map button.
Let's first look at NORTH UP. Notice how the north arrow is blue.
Click the NORTH UP list item.
NORTH UP is available when your system
is receiving location from location services or receiving both GPS location and track data.
The map screen does not rotate and remains centered on the current position in
You can now see the arrow has now changed to yellow
Click the ERA button.
Let's have a look at what happens when we change the ERA.
Click the REL list item.
Changing the ERA to REL will present you with arrows showing your up to four alternate aerodromes nearest to your current aircraft region that belong to your subscription.
Click the Map button.
Let's now have a look at TRK UP mode.
Click the TRK UP list item.
TRK UP is only available when you are receiving
both location and track data, with enough accuracy.
The map screen remains centered on the current position and rotates to follow the
track of the aircraft using the location position feed.
The current aircraft symbol will be shown – please verify the use of this mode against your operational approval.
In Charts+ iOS App Settings, you can modify "Position Feed HIGH/LOW Accuracy Threshold" parameter to set the threshold below which accuracy is declared LOW: 50m, 100m, 500m, 1000m. The own-ship symbol is displayed only if HIGH Accuracy is available.
For Charts+ Windows this parameter is available in C:\Program Files (x86)\Navtech\Navtech Charts\eCharts.Settings.ini file, with the parameter “Accuracy Threshold”.
Position Feed / track loss:
In App Settings, you can choose the position feed timeout period after which the own-ship symbol will be removed from the map. A "Navigational Data unavailable" pop-up will appear after this timeout period.
If only Track parameter is lost, a "Course unavailable" pop-up will appear (iOS only), and own-ship symbol will be removed from the map.
Let's have a look at the North symbols and their meanings and presentation in the different day and night modes.
In pan modes the map is rotated, or non-true North Up orientated, the map symbol rotates to point at the map's True North. Tapping on the north symbol will automatically re-orientate the map to North Up.
