The setting is applied immediately. Press Cancel or Reset Font to Default to revert back to previous.

The font for map display is not affected by this value and can be set separately on page Map Display.

Note

Little Navmap remembers the size of dialog windows. In some cases you have to resize dialog windows after changing to a larger font to see all content.

Warning

Keep in mind that using a wrong or too large font can result in display issues.

Tip

Try out the B612 Font family which is an open source font family designed and tested to be used on aircraft cockpit screens.

57.6.2. Enable high DPI monitor support

Toggle this is you have problems with scaled fonts or symbols on Windows, cannot shrink the main window or other issues.

You have to restart Little Navmap after changing.

57.6.3. Use FreeType font engine on Windows

This option is only available on Windows.

Disable this if you think the overall appearance of text in Little Navmap on Windows is blurry. Enabling this option results in better and faster text display on the map, especially for rotated labels.

But as a result, the text will appear slightly blurred throughout the whole application. Deselect this to avoid the slightly blurred text in menus and application windows.

Note

A restart is required after changing the font engine.

• Show other fuel units too: Shows kilogram and liter as small text besides main units if lbs and gallon are selected and vice versa. This is applied only to the most important fuel values like block and trip fuel, for example.

• Show true course and heading besides magnetic course in information displays: Add true heading as small text besides magnetic heading displays. This applies to information, progress as well as map display (traffic patterns and holds).

Note

See Signed Decimal Formats for more information when using Latitude and Longitude with sign or Longitude and Latitude with sign since these modes also affect coordinate input.

The format Degree, Decimal Minutes for Google is useful for input into Google Maps or Google Earth.

Warning

Note that any numbers used in the program are not converted when changing units.

That means that you will get a minimum altitude buffer of 1,000 meter after changing the setting Altitude and Elevation from feet to meter. This also applies to flight plan altitude. Therefore, do not forget to adapt these numbers after changing units.

57.8. Files

Various settings for loading and saving files.

57.8.1. Center flight plan or aircraft trail on the map after loading

Zooms to the loaded plans or trails after loading from the menu File or after using drag and drop from a file manager like Windows Explorer.

57.8.2. Avoid overwriting Flight Plan with not matching departure and destination

Check this option to avoid overwriting LNMPLN files with wrong flight plans after changing, departure, destination or any other parameter used in the flight plan file.

The dialog Save Flight Plan as LNMPLN will show up instead of overwriting the current flight plan when you reverse the route, for example.

57.8.3. Pattern for default LNMPLN flight plan names

Allows to customize the default file name which is proposed on first save of LNMPLN files ( Save Flight Plan and Save Flight Plan as LNMPLN).

See Flight Plan Multiexport for more information about how to customize the default file names for other flight plan formats which can be exported.

Error messages and an example is shown below the input field.

This pattern applies to new filenames when saving LNMPLN flight plans. The file suffix .lnmpln is added automatically.

The default value is PLANTYPE DEPARTNAME (DEPARTIDENT) to DESTNAME (DESTIDENT).

The input field falls back to the default if it is left empty or has errors.

The following variables are recognized:

• PLANTYPE: Text IFR or VFR depending on Flight Plan Type.

• DEPARTIDENT: Departure airport ident

• DEPARTNAME: Departure airport name

• DESTIDENT: Destination airport ident

• DESTNAME: Destination airport name

• CRUISEALT: Cruise altitude in selected unit (meter or feet).

All variables have to be entered in upper case letters. Other characters are used as entered.

57.8.3.1. Short

This button sets the flight plan file pattern to the short name DEPARTIDENT DESTIDENT.

Example: EDDF LIRF.lnmpln.

57.8.3.2. Long

This button sets the flight plan file pattern to the long name PLANTYPE DEPARTNAME (DEPARTIDENT) to DESTNAME (DESTIDENT).

Example: IFR Frankfurt am Main (EDDF) to Fiumicino (LIRF).lnmpln.

57.9. Map

Has map related customization options.

Hover the mouse above buttons and input fields to see more information.

57.9.1. Allow to undock the map window

Allows to undock and put the map window into a floating state which also results in more flexibility when positioning other dock windows.

This can cause several unwanted effects when arranging dock windows. Deselect this if you do experience problems when resizing dock windows.

You have to restart the program after changing this option.

See Window Layout for more information about window layouts which might be affected by this option.

• By airspace name vs. callsign: Use the airspace name within a file to assign the geometry to a center by callsign.

• By airspace file name vs. callsign: Use the airspace filename minus the .txt extension to assign the geometry to a center by callsign.

See chapter Loading Airspaces for more information.

57.19. Simulator Aircraft

Allows to change various aspects around the display of the user aircraft

57.19.1. Simulator Aircraft Updates

Settings resulting in a more fluid aircraft display will use more CPU and can potentially induce stutters in the simulator.

57.19.2. Aircraft Centering Options

This chapter explains the various options to modify the map updates while flying. The idea is to reduce manual scrolling or zooming as much as possible while piloting the aircraft.

Read the chapters below if you find the behavior confusing (i.e. map jumping unexpectedly). Otherwise leave the default values.

See User Aircraft Centering for general information about aircraft centering while flying.

57.19.2.1. Center map on aircraft and next flight plan waypoint

The map is zoomed to show both the aircraft and the next active waypoint on the flight plan if this is enabled while flying. Little Navmap uses several criteria to minimize map updates in this mode.

The map will fall back to the default mode of simply centering the aircraft if one of the conditions below is true:

• No flight plan loaded.

• Aircraft is on ground (no active magenta leg).

• Aircraft distance to flight plan is more than 40 NM (active magenta leg disappears).

You can change the zoom freely if the fall back is active.

57.19.2.2. Do not use box mode for following the aircraft. Move the map constantly.

Map will follow the aircraft constantly when checked. This is also used for Center map on aircraft and next flight plan waypoint.

This option will cause Little Navmap to consume more CPU resources while flying.

57.19.2.3. Simulator aircraft scroll box size (percent of map window size)

Smaller values keep the aircraft centered and will move the map more often. Larger values will update the map only when aircraft reaches map boundary.

This setting is only applicable if Center map on aircraft and next flight plan waypoint above is disabled.

57.19.2.4. Allow scrolling and zooming in the map and jump back to aircraft after

This setting allows an user to move around in the map without the need to manually disable the aircraft centering.

Time until aircraft following is activated again after any manual map interaction like scrolling or zooming.

You cannot move the user aircraft out of view if this option is disabled. The map will jump back immediately.

This option is also used in the Elevation Profile.

Allow scrolling enabled:

The map will stop following the aircraft for the given time if the user does any interaction with the map like scrolling or zooming. You can quickly check out the destination or your overall progress, and after you stop moving around, Little Navmap will return to following your aircraft.

This option is also used in Elevation Profile.

Toggle Center Aircraft on and off if you find that the map jumps back to the wrong position.

Allow scrolling disabled:

Map will constantly follow the aircraft and will not allow moving away from it.

The aircraft centering will be switched off only when using one of the following functions:

• Double-click into a table view or map display to zoom to an airport or a navaid.

• Context menu item Show on map.

• Goto Home or Goto Center for Distance Search.

• Map link in Information dock window.

• Show Flight Plan, when selected manually, or automatically after loading a flight plan.

• Centering a Google Earth KML/KMZ file after loading

This allows a quick inspection of an airport or navaid during flight. To display the aircraft again use Map Position Back ( Map Position Back/Forward) or enable Map follows User Aircraft again.

57.19.2.5. Zoom out on takeoff

Zooms out to a fixed zoom distance when a takeoff is detected.

This setting is only applicable if Center map on aircraft and next flight plan waypoint above is disabled.

57.19.2.6. Zoom in on touchdown

Zooms in to a fixed zoom distance to show airport details when a takeoff is detected.

57.19.2.7. Scroll flight plan table back to active leg after

The active (magenta) leg will be moved to the top of the flight plan table when a new leg is activated or there is no interaction with the table for the given time period.

57.19.2.8. Clear selection in flight plan table after

The selection in the flight plan table and highlights on the map will be cleared after there is no interaction with the table for the given time period.

57.19.2.9. Highlight active flight plan legs

Shows active flight plan legs in magenta color (default) on the map and in the flight plan table.

57.19.2.10. Maximum number of aircraft trail points:

Limits the number or aircraft trail to avoid performance issues when showing a too large number of trail points.

57.20. Flight Plan

Here you can set preferences for flight plan cruise altitude assignment.

57.21. Weather

Choose which weather services should be used to fetch and show METAR for airports in information window and map tooltips.

The weather type Flight Simulator will either display weather from the FSX or P3D connection or from X-Plane’s weather files.

The weather for a service is downloaded or read on demand when you enable the corresponding service for tooltips or information panels.

Online weather is downloaded and updated every ten minutes.

Note

Simulator weather is not supported for Microsoft Flight Simulator 2020 since this simulator lacks the needed programming interfaces.

57.22. Weather Files

Active Sky can only be selected if either Active Sky Next, AS16, Active Sky for Prepar3D v4 or Active Sky XP are installed or the weather file is selected directly. Selecting the Active Sky weather file directly can be useful if you run a networked setup. Use Windows shares or a cloud service to get access to the file on the remote computer.

The URLs of various weather services can be modified if you like to use another source. Usually there is no need to change these values.

Note that leading and trailing spaces are removed from the web addresses.

You can change the path to the X-Plane weather files if you’d like to load it on a remote computer using a network share.

The buttons Test for the online weather services can also be used to find out if Little Navmap can connect to Internet. Check your firewall settings if these fail.

Use Reset to set a value back to default if you change something accidentally.

Note

While this happens rarely, some public services like NOAA might be interrupted for hours. Little Navmap will show error messages if this is the case.

You might want to check you internet access but otherwise ignore these if it does not happen for a longer time.

57.23. Online Flying

This page allows to change settings for online networks.

VATSIM, IVAO and PilotEdge provide pre-configured options to connect to the services.

Use Custom with status file if you have a status file pointing to whazzup.txt files. Use Custom if you’d like to load a whazzup.txt file directly.

57.23.2.4. Format

IVAO or VATSIM. Depends on the format used by your private network. Try both options if unsure or you see strange effects like all aircraft pointing to the north.

57.24. Web Server

Configuration options for the internal web server of Little Navmap.

• Document root directory: The root directory of the web server pages. Change this only if you would like to run a customized web server using your own style sheets and you own HTML templates.

• Select Directory ...: Select root directory. Little Navmap will show a warning if no index.html file is found in the root directory.

• Port number: Default 8965. That means you have to use the address http://localhost:8965/ or similar in your browser to access the web page of Little Navmap, for example. Change this value if you get errors like Unable to start the server. Error: The bound address is already in use..

• Use encrypted connection (HTTPS / SSL): Encrypted connections use a pre-computed self-signed certificate which comes with Little Navmap. A browser will show an error message if using this certificate and requires to add a security exception. The encrypted address is https://localhost:8965/, for example. Creating a self signed certificate is quite complex. Look at the various web articles by searching for How to create a self signed certificate.

• Start Server: Start or stop the server to test the changes above. The server status (running or not running) is reverted to the previous state when pressing Cancel in the options dialog.

• Label Web Server is running at http://my-computer:8965 (IP address http://192.168.1.1:8965): Shows a list of valid links using the IP address and the host name (your computer name) of the web server. Clicking on either one opens the page in your default browser. You can always try the IP addresses if the computer names does not work. Some addresses might not work depending on network configuration.

  Note that the IP address of a computer can change for every reboot depending on network or router configuration. Try to use the host name which is stable.

  The list contains all computer addresses for IPv4 (like my-computer:8965 (192.168.1.1:8965)) and IPv6 (like my-computer:8965 (fe80::c0b9:1832:abc5:d5a1:8965)).

  You might see more than one IPv4 address (e.g. one for WIFI and one for Ethernet) and several addresses for IPv6 if enabled.

See Web Server for detailed information.

57.25. Cache and Files

57.25.1. Map Display

Here you can change the cache size in RAM and on disk. These caches are used to store the downloaded images tiles from the online maps like the OpenStreetMap or OpenTopoMap.

All image tiles expire after two weeks by default and will be reloaded from the online services then.

You can delete the files manually using your file manager. You can also open the cache directory from menu Tools -> Files and Directories -> Show Map Cache or by clicking on the button Show Disk Cache in File Manager.

The RAM cache has a minimum size of 100 MB and a maximum size of 2 GB.

57.25.2. Map Display Themes

You can select a directory to lookup additional map themes for the background map layer. Each map theme has to consist of a directory containing the related .dgml and other files. See Map Themes for installation instructions.

External map themes are ignored if this field is empty.

Warning

Do not use the path .../data/maps/earth in the installation directory do install maps. This location is deprecated.

57.25.3. Install GLOBE elevation data

See GLOBE Offline Elevation Data for more information about the offline elevation data and how to download and install it.

57.26. Scenery Library Database

Allows to configure the loading of the scenery library database.

Note that these paths apply to all Flight Simulators, FSX, P3D, MSFS and X-Plane.

You have to reload the scenery database in order for the changes to take effect.

Little Navmap supports linked scenery which is linked by symbolic links (all operating systems), Windows shortcuts, Windows junctions and macOS aliases. Note that this functionality is limited to the MSFS Community and X-Plane Custom Scenery directories. Other combinations are not tested.

57.26.1. Scenery library directories to include when loading

This list shows extra directories which are loaded additionally when reading the simulator scenery library. Add-on airports in the extra directories extending MSFS Community, X-Plane Custom Scenery or FSX/P3D Addon Scenery are read when loading the simulator scenery library database.

Note that airport files in this list are always read last which can affect the display in MSFS, FSX or P3D.

Tip

The add-ons in the selected directory and will be read recursively which means you can use sub-directories to organize your add-ons.

57.26.2. Scenery library directories or files to exclude from loading

All directories including sub-directories as well as files in this list will be omitted when loading the scenery library into the Little Navmap database. You can also use this list to speed up database loading if you exclude directories that do not contain airports or navaids (landclass, elevation data and others).

You can also exclude FSX, P3D, MSFS BGL or X-Plane apt.dat files if needed.

Select one or more entries in the list and click on Remove to delete then from the list.

Tip

Note that you can select more than one entry in the file dialog to add several entries at once.

57.26.3. Scenery library directories to exclude from add-on recognition

FSX/P3D: All scenery data that is found outside of the base flight simulator Scenery directory is considered an add-on and will be highlighted on the map as well as considered during search for add-ons.

X-Plane: All airports in the Custom Scenery directory are considered add-on airports and will be highlighted accordingly.

Microsoft Flight Simulator 2020: All airports located in the Community directory and the Official\OneStore or Official\Steam are considered to be add-on airports. Exceptions are fs-base, fs-base-genericairports and fs-base-nav.

You can use this list to modify this behavior.

Add-ons, like Orbx FTX Vector or fsAerodata add scenery files that correct certain aspects of airports like elevation, magnetic declination or others. All these airports will be recognized as add-on airports since all their files are not stored in the base flight simulator Scenery directory.

Insert the corresponding directories or files into this list to avoid unwanted highlighting of these airports as add-ons.

Page Scenery Library Database with three directories and three files excluded from loading and two directories excluded from add-on recognition.

57.26.4. Examples

Provided your simulator is installed in C:\Games\FSX.

57.26.4.1. ORBX Vector

Exclude the directories below from add-on recognition. Do not exclude them from loading since you will see wrong airport altitudes.

• C:\Games\FSX\ORBX\FTX_VECTOR\FTX_VECTOR_AEC

• C:\Games\FSX\ORBX\FTX_VECTOR\FTX_VECTOR_APT

57.26.4.2. Flight1 Ultimate Terrain Europe
