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.

Startup

Allows to customize what should be loaded and shown on startup of Little Navmap.

User Interface

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

You can also change the overall style for the graphical user interface. The user interface styles contain a Night mode that can be used for night flights in dark rooms. You can also dim the map and elevation profile display.

A restart is not needed but recommended after changing a style.

The colors for the styles Fusion and Night can be changed by editing configuration files. See Customize for more information.

User Interface

Picture above: Tab User Interface using the style Night.

Map

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

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 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.

Units

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

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 lower part of this tab allows to install the 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 a10g to p10g. The label in the dialog will show an error if the path is invalid.

Flight Plan

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

Weather

You can select the various weather sources that should be shown in the Information dock window or in the map tooltips.

Active Sky can only be selected if Active Sky Next or AS16 is 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

Scenery Library Database

Allows to configure the loading of the scenery library database.

Note that these paths apply to all Flight Simulators.

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).

Select Paths to exclude add-on recognition

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 and also considered during search for add-ons.

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 directory into this list to avoid unwanted highlighting of these airports as add-ons.

Scenery Library Database
