Options Options Dialog

Most options are self-explaining and tooltips contain more detailed explanations if applicable.

You can immediately check the effect of your changes on the map display by moving the dialog Options to the side and pressing Apply.

The button Restore Defaults only restores the options of this dialog back to default. Other settings like map display, table views or dock window positions are not affected. To reset all saved settings completely see Troubleshoot.


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.

User Interface

Has options for text sizes in information windows and flight plan as well as the search result table.

This tab 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.

User Interface

Picture above: Tab User Interface using the style Night.


Has map related customization options. Allows to set the click sensitivity, zoom distances and more.

Avoid blurred map display by zooming out to next best step

Checking this helps to get a sharp background image for online maps (e.g. from OpenStreetMap) when Little Navmap zooms to or centers map features like airports, the active flight plan leg and others. This works best with the map projection Mercator.

As a result the map might be zoomed out farther than expected in some cases.

Map Display

This tab contains options for symbol and text sizes, flight plan and aircraft trail colors and more.

The right side of the tab contains a tree view that allows to select the text labels that should be shown at airports, user aircraft and AI/multiplayer aircraft.

Map Display

Picture above: Tab Map Display.


You can change all units that are used by Little Navmap on this tab 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 have 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.

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.

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.

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.

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.

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.

Allow scrolling and zooming in the map

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 the Flight Plan Elevation Profile.

Note if you use the default aircraft centering mode or if Little Navmap falls back to this mode (see above):

  1. Using the mouse wheel or the + and - key to zoom will change and keep the zoom distance. The aircraft is still centered but the new zoom distance is used.
  2. 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 link.

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

This option is also used in the Flight Plan Elevation Profile.

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.

Cache and Files

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, OpenMapSurfer 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.

Flight Plan Elevation Profile

The bottom part of this tab allows to install the the freely downloadable GLOBE - Global Land One-km Base Elevation Project elevation data.

Look for posts in the support forum at AVSIM if the original download is not available.

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 a10g to p10g. The label in the dialog will show an error if the path is invalid.

GLOBE Elevation Data

Picture above: Tab Cache and Files with properly selected GLOBE elevation data.

Flight Plan

Here you can set preferences for flight plan calculation or adjust the rule of thumb for the top of descent display.


You can select the various weather sources that should 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 the NOAA and VATSIM weather can be modified if you like to use another source or the services change the URLs.

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.

Weather Options

Picture above: Tab Weather with manually selected Active Sky weather file on a network share.

Online Flying

This tab allows to change settings for online networks.

Note that all related window tabs, menu items and toolbar buttons are hidden if this is set to None.

See Online Networks for an overview.

Not all networks might be enabled depending on release.

Online Network Options

Picture above: Tab Online Flying with VATSIM network enabled.

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.

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 whazzup.txt file.


This option allows to connect to a private network and will periodically download a whazzup.txt file which contains information about online clients/aircraft and online centers/ATC.


Status File URL

URL of the status.txt file. You can also use a local path like C:\Users\YOURUSERNAME\Documents\status.txt.

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 local paths.

The status file format is explained in the IVAO documentation library: Status File Format.

Whazzup File URL

URL of the whazzup.txt file. You can also use a local path like C:\Users\YOURUSERNAME\Documents\whazzup.txt.

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.

Example for a whazzup.txt file:

UPDATE = 20181126131051


Update Every

Sets the update rate that defines how often the whazzup.txt file is downloaded.

Allowed values are 30 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 if downloads are excessive.


IVAO or VATSIM. Depends on the format used by your private network. Try both options if unsure.

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.

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 BGL or 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.

Select Paths to exclude 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 folder 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 variance 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.

Scenery Library Database

Picture above: Tab Scenery Library Database with three directories and three files excluded from loading and two directories excluded from add-on recognition.


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

ORBX Vector

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

Flight1 Ultimate Terrain Europe

Exclude these directories from loading to speed up the process:

  • C:\Games\FSX\Scenery\UtEurAirports
  • C:\Games\FSX\Scenery\UtEurGP
  • C:\Games\FSX\Scenery\UtEurLights
  • C:\Games\FSX\Scenery\UtEurRail
  • C:\Games\FSX\Scenery\UtEurStream
  • C:\Games\FSX\Scenery\UtEurWater
ORBX Regions

Exclude these directories from loading:
