Most options are self-explaining and tooltips contain more detailed explanations if applicable.
Restore Defaults restores only the options of this dialog
back to default. Other settings like map display, table views or dock
window positions are not affected. You can press
Cancel to close the
dialog and undo this action.
To reset all saved settings completely see Reset all Settings and Restart.
The following chapters give a brief description of each page.
You can immediately check the effect of your changes on the map display
by moving the dialog
Options to the side and pressing
40.1. Startup and Update¶
Allows to customize what should be loaded and shown on startup of Little Navmap.
You can also configure the frequency of the automatic update check and channels. See Checking for Updates for more information. Change the settings here if you wish to get notifications about beta releases.
40.2. User Interface¶
Has options for high DPI support, text sizes in information windows and flight plan as well as the search result table.
This page also contains options to force the program language and locale settings (number, date and time formats) to English if you do not want to use a translated user interface.
Has map related customization options. Allows to set the tooltips, scroll performance and more.
40.5. Map Display¶
This page contains options for symbol sizes, text sizes, flight plan, user aircraft trail colors and more.
40.6. Map Display 2¶
More display options for user features like range rings and more.
The right side of the page contains a tree view that allows to select the text labels that should be shown at airports, user aircraft, AI/multiplayer aircraft and other map features.
Tooltips give explanations for the various settings in the tree.
40.7. Map Display Online¶
This page allows to change the default center circle sizes for online centers.
Two options below
Online Center Boundary Lookup in User Airspaces
can be used to assign OpenAir airspaces from the user airspace database
to centers by matching filename or airspace name with the callsign of
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
.txtextension to assign the geometry to a center by callsign.
See Online Airspaces for more information.
You can change all units that are used by Little Navmap on this page between nautical, imperial and metric. Mixed settings like meter for altitude and nautical miles for distance are possible.
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 1000 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.
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 about the coordinate formats
Latitude and Longitude with sign
Longitude and Latitude with sign :
- Latitude: Negative is south and positive is north.
- Longitude: Negative is west and positive is east values.
Choosing these display formats will also enable input of signed decimal values. The reading order for coordinates will also change depending on the chosen format above when entering signed numbers.
40.9. Simulator Aircraft¶
Allows to change various aspects around the display of the user aircraft while flying. All settings resulting in a more fluid aircraft display will use more CPU and can potentially induce stutters in the simulator.
40.9.1. 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 no flight plan is loaded, the aircraft is on ground or the flight plan is more than 50 nm away from the user aircraft.
40.9.2. 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
Center map on aircraft and next flight plan waypoint.
This option will cause Little Navmap to consume more CPU resources while flying.
40.9.3. 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 ignored when
Center map on aircraft and next flight plan waypoint is checked and
a flight plan is set.
40.9.4. Keep active leg on top of flight plan table¶
The active (magenta) leg will be shown on top of the flight plan table when a new leg is activated.
40.9.5. Allow scrolling and zooming in the map¶
126.96.36.199. Allow scrolling Active¶
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.
Note if you use the default aircraft centering mode or if *Little Navmap* falls back to this mode (see above):
- Using the mouse wheel or the
-key to zoom will change and keep the zoom distance. The aircraft is still centered but the new zoom distance is used.
- Starting to look around by moving the map with mouse drag or cursor keys: This will remember the last position and the zoom distance. You can do any map movements and Little Navmap will jump back to the last position and zoom distance where you started the movement when time is over.
The same from point two applies if you jump to airports, navaids or
other features by double click, context menu (
Show on Map) or map
Center Aircraft on and off if you find that
the map jumps back to the wrong position.
This option is also used in Elevation Profile.
188.8.131.52. Allow scrolling not active¶
The aircraft centering will be switched off when using one of the following functions. Note that this default behavior can be modified in the options dialog.
- Double-click into a table view or map display to zoom to an airport or a navaid.
- Context menu item
Show on map.
Goto Center for Distance Search.
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 or enable
Show Aircraft again.
40.9.6. Jump back to aircraft and resume aircraft following after this time¶
Time until aircraft following is activated again after any map interaction like scrolling or zooming.
40.10. Flight Plan¶
Here you can set preferences for flight plan calculation or change the default filename for saving flight plans.
You can select the various weather sources to be shown in the
Information dock window or in the map tooltips.
The weather type
Flight Simulator will either display weather from
the FSX or P3D connection or from X-Planes
METAR.rwx weather file.
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.
You can change the path to the X-Plane weather file if you’d like to load it on a remote computer using a network share.
The test buttons 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.
40.12. Online Flying¶
This page allows to change settings for online networks.
See Online Networks for an overview.
40.12.1. Online Service¶
Disables all online services and hides all related window tabs, menu items and toolbar buttons. No downloads will be done.
Uses the predefined configuration for the VATSIM network. No other settings are needed.
The update rate depends on configuration and is typically three minutes.
Uses the predefined configuration for the IVAO network. No other settings are needed.
The update rate depends on configuration and is typically three minutes.
184.108.40.206. Custom with Status File¶
This option allows to connect to a private network and will download a
status.txt file on startup which contains further links to e.g. the
This option allows to connect to a private network and will periodically
whazzup.txt file which contains information about online
clients/aircraft and online centers/ATC.
220.127.116.11. Status File URL¶
URL of the
status.txt file. You can also use a local path like
This file is downloaded only on startup of the program.
A push button
Test allows to check if the URL is valid and shows the
first few lines from the downloaded text file. This does not work with
The status file format is explained in the IVAO documentation library: Status File Format.
18.104.22.168. Whazzup File URL¶
URL of the
whazzup.txt file. You can also use a local path like
This file is downloaded according to the set update rate.
A push button
Test allows to check if the URL is valid. The test
does not work with local paths.
The whazzup file format is explained in the IVAO documentation library: Whazzup File Format.
!GENERAL VERSION = 1 RELOAD = 1 UPDATE = 20181126131051 CONNECTED CLIENTS = 1 CONNECTED SERVERS = 41 !CLIENTS :N51968:N51968:PILOT::48.2324:-123.1231:119:0:Aircraft::::::::1200::::VFR:::::::::::::::JoinFS:::::::177::: !SERVERS ...
22.214.171.124. Update Every¶
Sets the update rate that defines how often the
whazzup.txt file is
Allowed values are 5 to 1800 seconds, 180s being the default.
You can use smaller update rates for private online networks to improve map display updates.
Do not use update rates smaller than two minutes for official online networks. They might decide to block the application or block you based on your internet address if downloads are excessive.
VATSIM. Depends on the format used by your private
network. Try both options if unsure.
40.13. 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.htmlfile is found in the root directory.
Port number: Default 8965. That means you have to use the address
http://localhost:8965/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
Cancelin the options dialog.
Web Server is running at http://my-computer:8965 (IP address http://192.168.1.1:8965): Shows two links to the web server. Clicking on either one opens the page in your default browser. You can always try the IP address link if the first link using the computer name does not work.
See Web Server for detailed information.
40.14. Cache and Files¶
40.14.1. 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 and will be reloaded from the online services then.
Note that a reduction of size or erasing the disk cache is done in background and can take a while.
The RAM cache has a minimum size of 100 MB and a maximum size of 2 GB.
The disk cache has a minimum size of 500 MB and a maximum size of 8 GB.
40.14.2. Flight Plan Elevation Profile¶
The bottom part of this page allows to install the freely downloadable GLOBE - Global Land One-km Base Elevation Project elevation data.
Download the ZIP archive from the link in the dialog and extract it.
Select the extracted directory using
Select GLOBE Directory ... so,
that it points to the files
p10g. The label in the
dialog will show an error if the path is invalid.
40.14.3. User Airspaces¶
You can select the path to the user airspaces and file extensions to read. Little Navmap reads all OpenAir files with the given extension in the selected directory recursively into the user airspace database.
You can provide more than one file extension using a space separated list.
40.15. Scenery Library Database¶
Allows to configure the loading of the scenery library database.
Note that these paths apply to all Flight Simulators, FSX, P3D and X-Plane.
You have to reload the scenery database in order for the changes to take effect.
40.15.1. Select Paths to exclude from loading¶
All directories including sub-directories 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
DAT files if needed.
Note that you can select more than one entry in the file or directory dialogs.
Select one or more entries in the list and click on
Remove to delete
then from the list.
40.15.2. Select Paths to exclude add-on recognition¶
FSX/P3D: All scenery data that is found outside of the base flight
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.
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
Insert the corresponding directories or files into this list to avoid unwanted highlighting of these airports as add-ons.
Provided your simulator is installed in
126.96.36.199. ORBX Vector¶
Exclude the directories below from add-on recognition. Do not exclude them from loading since you will see wrong airport altitudes.
188.8.131.52. Flight1 Ultimate Terrain Europe¶
Exclude these directories from loading to speed up the process:
184.108.40.206. ORBX Regions¶
Exclude these directories from loading:
