The installation of Little Navmap does not change any registry entries (in Windows) and involves a simple copy of files therefore an installer or setup program is not required.

Do not extract the archive into the folder c:\Program Files\ or c:\Program Files (x86)\ since this requires administrative privileges for some Windows versions. Windows keeps control of these folders, therefore other problems might occur like replaced or deleted files.

Extract the Zip archive into a folder like c:\Little Navmap. Then start the program by double-clicking littlenavmap.exe. See First Start for more information on the first start after installation.

In some cases you have to install the Update for Visual C++ 2013 and Visual C++ Redistributable Package. Install both 32 and 64 bit versions. Usually this is already installed since many other programs require it.

Little Navmap is a 32-bit application and was tested with Windows 7, Windows 8 and Windows 10 (32-bit & 64-bit). Windows XP is not supported.

Installing over a previous Release

rvwu ov I recommend to delete all installed files of a previous Little Navmap version before installing a new version. All files from the previous ZIP can be deleted since settings are stored in separate directories (except custom map themes). In any case do not merge the installation directories.

See Files for more information about configuration and database files. Do not delete these.

Other Simulators than FSX SP2

This program was compiled using plain FSX SP2 (no Acceleration) SimConnect version 10.0.61259.0.

You might have to install an older version of SimConnect if you use Prepar3D or FSX Steam Edition. If not sure about this simply try Little Navmap out. If it fails with an error message follow the instructions below:

Prepar3D: In the same directory as Prepar3D.exe is a redist\Interface directory (normally C:\Program Files (x86)\Lockheed Martin\Prepar3D v3\redist\Interface). There are multiple legacy versions of SimConnect available. You have to install FSX-SP2-XPACK.msi for Little Navmap.

FSX Steam Edition: The installation adds the folder C:\Program Files (x86)\Steam\SteamApps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces where you can find the legacy SimConnect interfaces.

Quick Overview

Little Navmap Overview

General Remarks

User Interface

The user interface of Little Navmap consists of a main window and several dock windows which can be detached from the main window or arranged in any order within the main window.

The docked windows can be moved around in their docked position and can be detached from the main window by simply dragging them outside of the main window, by double clicking their title bar or by clicking on the window symbol on the top right.

Double click on the docked window's title bar or click on the window symbol again to move the windows back into their docked position.

All docked windows except the map window can be closed if they are not needed. You can even drop docked windows on each other to create a tabbed view. The tabs will appear at the bottom of the dock stack in this case.

Toolbars are also movable by clicking on the left handle and can also be closed or detached from the main window.

Use the Main Menu -> Window menu to bring docked windows or toolbars back.

The Main Menu -> Reset Window Layout menu item can be used to reset the state and positions of all dock windows back to their default.

The program uses tooltips to display more information on buttons and other controls.

A more detailed description is shown on the left side of the statusbar if you hover the mouse over a menu item.

The main window title indicates the currently selected flight simulator database (FSX, FSXSE, P3DV2, P3DV3 or P3DV4), the flight plan file name and a trailing * if the flight plan has changes.

Almost all dialogs, text labels and all information windows in Little Navmap support copy and paste. You can select the text using the mouse and then either use Ctrl+C or the context menu to copy it into the clipboard. The information and simulator aircraft windows even support copying of formatted text including the icons.

The table views for the flight plan or airport/navaid search results allows copying of the results in CSV format into the clipboard which can be imported into a spreadsheet program like LibreOffice Calc or Microsoft Excel.

Translation and Locale

Little Navmap is currently only available in English. I will happily support anybody who would like to translate the user interface or manual into another language.

Despite using the English language in the user interface the locale settings of the operating system will be used. So, e.g. on a German version of Windows you will see comma as a decimal separator instead of the English dot.

Please note that some screenshots in this manual were taken using German locale, therefore a comma is used as a decimal separator and a dot as a thousands separator.

Map Legend

The legend explains all the map icons and the Flight Plan Elevation Profile icons. It is available in the Legend dock window or in this manual: Legend.

Naming Conventions used in this Manual

See the glossary for explanations of common terms in this manual.


Airports get a zero to five star rating depending on facilities. Airports that have no rating are considered boring and will be displayed using a gray symbol below all other airports on the map (Empty Airport). This behavior can be switched off in the Options dialog on the Map Display tab. The criteria below are used to calculate the rating. Each item gives one star:

  1. Add-on
  2. Parking positions (ramp or gate)
  3. Taxiways
  4. Aprons
  5. Tower building (only if at least one of the other conditions is met).

The latest navigation data can be installed from fsAerodata or FSX/P3D Navaids update. This will update the flight simulator stock data and airports which are read into Little Navmap's scenery database.

Certain navaid and procedure types are only available through fsAerodata. These are VORTAC and TACAN navaids as well as SID and STAR procedures.

Navdata updates are optional.

First Start

The Scenery Library Dialog dialog will be shown when starting Little Navmap for the first time. From there you can select all recognized Flight Simulators and load their scenery libraries into Little Navmap's internal database. One database is kept for each simulator and can be changed on the fly in the Scenery Library menu.

A warning dialog will be shown when starting Little Navmap the first time on a system without any flight simulator installations. See chapter Running without Flight Simulator Installation for more information on this.

One or more scenery library databases may need to be updated when you install a new version of Little Navmap. A question dialog will pop up prompting you to erase the now incompatible database. You can reload the scenery in the Scenery Library Dialog after erasing the databases.

I recommend to have a look at the tutorials if you use the program the first time.
