This is a public beta release which is feature complete but might have issues. Furthermore, translations are incomplete, some help links do not work and the user manual is not adapted yet to the new features. Feel free to ask if something is not clear.

A big thank you to all who reported bugs and issues!

This version is ready MSFS SU10 and for X-Plane 12 and also supports FSX, P3D and X-Plane 11.

Some features like MSA, vertical paths or en-route holdings require either X-Plane, the included AIRAC 1801 database or a Navigraph database newer or equal than AIRAC 2201.

See here for a list of issues done. More issues are solved than publicly known on Github. This changelog lists the most important.

Please report if something does not work or does not work as expected.

Little Navmap will remind you to reload the scenery library after updating. Please do so to benefit from new features and bug fixes.

Note that certains settings are reset to default after updating to 2.8.

A few keyboard shortcuts have changed.

Create a backup of your settings and database folder just in case you’d like to go back to the stable release. Backup ABarthel in C:\Users\YOURUSERNAME\AppData\Roaming\ABarthel on Windows and $HOME/.config/ABarthel on Linux and macOS.

Or see Multiple Installations for information how to run the stable and beta versions in parallel.

Known Issues

  • X-Plane 12 weather and winds aloft are not read from the simulator yet. This will be added in the next release. Use NOAA as a workaround for now.
  • Xpconnect build for Apple Silicon CPUs (ARM architecture) not yet available. You can run X-Plane in the Intel emulation Rosetta as a workaround: How to force a native M1 Mac app to run as an Intel app instead.
  • En-route holding courses are not correct due to an error in declination calculation. This will be fixed with AIRAC cycle 2210.
  • Running Little Navmap with autoconnect for P3D, FSX or MSFS for several hours without starting the simulator leaks resources. This is mitigated by automatically reducing the connection rate after 30 minutes. Disable autoconnect or quit the program to avoid this.
  • MSFS marker beacons and airport fuel are not recognized for SU10. #919

Changes from 2.6.19 to 2.8.0.beta

Map Display

  • Added turn prediction line for user aircraft also having tick marks for half and one NM distance. Enabled by default in menu View -> Show Turn Flight Path.
  • Added option to display selected autopilot altitude range as a dark green arc on the map. Enable this in menu View -> Show selected altitude range. Note that some add-on aircraft misuse the autopilot altitude which results in a wrong display. #247
  • Outline color (old and default style in Little Navmap) and semi-transparent (like SkyVector) option for flight plan added. Option for semi-transparent flight plan line also affects logbook preview and procedure preview. See options on page Map Display Flight Plan.
  • Added display on map and elevation profile for GLS paths. Showing information for GLS paths in tooltip and info window now. Now showing GLS channel information in flight plan table for GLS approach. Enable RNP/GPS path display in menu View -> Navaids -> Show GLS Approach paths or elevation profile context menu.

Enable in menu View -> Show Aircraft Endurance. Note that this shows the endurance based on current fuel flow. Numbers on range ring shown in warning and error colors depending on endurance. #341
  • Added forced navaid display for recommended navaids from used procedures including indication in tooltip. This means that a related VOR being part of a procedure in a flight plan is shown even if the display of VOR is disabled. This allows to have a clean map with only flight plan related navaids.
  • Added display of MSA (minimum sector altitude) diagrams on map similar to range rings. Can be set by user in map, flight plan table, airport search and navaid search context menus. Enable display of MSA icons in menu View -> Navaids -> Show MSA Sectors. Enable a larger scaled display by right clicking on the MSA icon and selecting Add MSA diagram at .... #498

  • Now hiding all artificial waypoints created internally for procedure or airway resolution from search, information and tooltips.
  • ILS and GLS information is now always taken from Navigraph database except when using Do not use Navigraph Database. As a result ILS course might probably not match for older scenery data or airport add-ons. Select Do not use Navigraph Database temporarily if this is an issue.


  • Now ignoring invalid waypoints with empty ICAO region code and invalid type as they appear in some MSFS add-on sceneries. This fixes the exception NOT NULL constraint failed: tmp_waypoint.region ... when loading. #910
  • Now also loading BGL files from missions to catch respective airports.
  • Changed handling for MSFS file Content.xml for SU10 and fixed crash when reading new file layout. Priorities for known base folders are now forced to lowest values to ensure the correct loading order. Other folders are loaded without any special order if not set in Content.xml.
  • Fixed bug where Little Navmap would only read and display a single transition from add-on (Community) SIDs and STARs, despite these procedures actually having more than one transition. This happens when using the latest MSFS SDK (SU9 or later). Thanks a lot to flpduarte at Github for the fix.
  • Added messages for encrypted MSFS add-ons when reading the scenery library. This helps to identify unreadable airports.
  • More fixes around MSFS scenery library loading.


  • Data compilation adapted for X-Plane 12 folder changes. #867
  • X-Plane now requires x-plane_install_11.txt or x-plane_install_12.txt and a valid installation path to be recognized. Run X-Plane once to create this file so that Little Navmap can detect it.
  • Now skipping empty X-Plane apt.dat files and files having empty lines in the header to avoid program freezing when reading malformed files.
  • Added airport transition level for X-Plane. This is not yet enabled in the Navigraph database.
  • Fixed issue Index out of bounds: Index: 5, size: 5 when reading X-Plane user_fix.dat with optional last column missing.
  • More X-Plane related fixes.

Command Line #431

Start program with the help option -h from a terminal to see available command line options.

  • Added command line option -f or --flight-plan to load a flight plan file on startup using one of the supported formats (.lnmpln, .pln, .fms and more).
  • New command line option to load and parse a flight plan route description (-d or --flight-plan-descr). For example, use littlenavmap.exe -d "KYKM WENAS7 PERTT 4741N12051W DIABO J503 FOLDY YDC PIGLU4 CYLW CYYF CZGF" to load plan on startup.
  • Aircraft performance file can now be loaded from command line with option -a or --aircraft-perf.
  • Added option -p or --settings-path to change full path to settings and databases using an absolute folder or a path relative to the installation folder. This allows to put all settings and databases on another drive or into the installation folder.
