Version 2.7.10.develop

Notes

This is a public development/alpha release. Not all features are implemented yet for the next
stable 2.8 branches. Translations are incomplete, new help links do not work and user manual is not
adapted.

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 to do and a
list of issues done.
Usually more issues are solved than publicly known on Github. This changelog lists all.

Note that all dialogs, windows, menus and buttons are functional. There are no unfinished or fake
buttons/dialogs in the program despite being an alpha release. Tooltips are updated with all new
functions and give help. Help buttons are an exception since the manual is not updated yet.

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

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 alpha versions in parallel.

Reload the scenery library after updating.

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

Known Issues

• Enroute holding courses are not correct due to an error in declination calculation.
• Running Little Navmap with autoconnect for P3D, FSX or MSFS for several hours without starting
  the simulator leaks resources. Disable autoconnect or quit the program to avoid this.

Changes from 2.7.9.develop to 2.7.10.develop

Flight Plan

• Fixed issue where alternate airport was lost and error message remained after switching databases.
• Fixed issues where runway was wrongly detected on circle-to-land approaches.
• Corrected mapping of parking names for empty or invalid MSFS parking spots which broke reloading
  of parking positions from flight plans. Exported MSFS PLN files now have correct parking name set
  for these cases.
• Extended waypoint coordinate parser for all ARINC 424 Code Convention full degree waypoint formats
  like 57N30, 5730E or 57S30. Flight plan route description can now read these waypoints
  independent if they are in the navdata or not.
• Fixed issue appearing when airport altitude from simulator is reported higher than procedure
  runway altitude from navdata. Program showed wrongly a violated altitude restriction at runway for
  an approach procedure and refused to build elevation profile.
• Fixed issue where flight plan leg in elevation profile had wrong position offset related to
  restriction when using online elevation data.
• Solved numerous problems with elevation profile calculation and vertical paths. Vertical
  paths are now considered as restrictions and enforced while calculating profile. Error messages
  can appear if altitude restrictions related to a vertical path are violated by a too low cruise
  altitude.
• Now always forcing flight altitude down to lowest allowed by restriction for
  FACF (final approach course fix) and FAF (final approach fix) points to avoid entering final
  approach too high.
• Related navaids now use notation with prefix R like R090 for radials instead of °M.

Map

• Combined the three toolbar buttons for map detail into one drop down menu button on the toolbar
  containing a slider and reset menu item. Moved map detail level settings from menu 'View' to menu Map.
• Replaced map theme and map projection boxes in toolbar with a new tool button having a drop
  down menu (dark globe icon on toolbar). This saves space in the toolbar area. Removed
  Map Projection and Theme Toolbar.
• Added button and menu item to disable online aircraft and simulator AI separately. #54
• Fixed issue where using Ctrl++ and Ctrl+- for more and less map details zoomed in or out at
  end of detail level range. #35
• Adjustments for map layers to display airway and track waypoints earlier when zooming.
• Fixed several issues where VOR or NDB being part of airways or tracks were not shown on the map.
• Added bearing, distance and altitude to AI/multiplayer and user aircraft tooltip. Fixed several
  issues where tooltip was not updated.
• Changed map theme handling to avoid issues when installing or removing map themes. Added error
  checking and reporting for invalid and duplicate theme. Map theme ids and source directories
  (disk cache) have to be unique now.
• Fixed issue where new airspaces were not shown after loading user airspaces.
• Now setting map projection for online services always to Mercator to avoid garbled map display in
  web user interface.
• Improved key dialogs in options on page Map Display Keys and added related links to map services.
• Added button and configuration dialog to add Mapbox user style configuration from style URL which
  can be taken from the Mapbox page. Dialog contains explanations.
• Fixed wrong warning dialog about key quadIndex key in DGML map theme configuration.
• Now keeping highlighted online airspaces when updating online network centers.
• Wind pointer is now kept when disabling aircraft display. Wind pointer can be disabled in options
  on page Map Display Labels in branch Top of Map.

Elevation Profile

• Moved elevation profile display settings from page Map Display in options dialog into a
  separate configuration dialog. Added menu item in Tools, elevation profile context menu
  and a button in elevation profile window for configuration options.
• Added new options for elevation profile to disable highlighting and some graphical elements.
• Fixed display issues where top label in profile was not hidden in some cases.
• Improved text display on elevation profile. Merging duplicate texts now. Better placement for TOC
  and TOD labels in elevation profile.
• Added configuration option for elevation profile to hide altitude restriction blocks.
• Zooming with the touchpad is now less sensitive in the elevation profile.

Scenery Library

• Updated database minor version to 25. Reloading is advised. User will be notified of this.
• 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 warning messages for encrypted MSFS add-ons when reading the scenery library. This helps to
  identify unreadable airports.
• Fixed issue where airport frequencies were not correctly written into the scenery library database
  for MSFS resulting in wrong search results when looking for towered airports, for example.
• Now skipping empty X-Plane apt.dat files to avoid program freezing when reading malformed files.
• Fixed issue where OpenAir airspace files were not recognized as OpenAir format in some cases.

User Interface

• Added options to display speeds, altitude and vertical speed in other than selected default units.
  This is for indicated and actual altitude as well as indicated, ground and vertical speed in the
  progress display tab. Enable this in menu Tools -> Aircraft Progress Display Options. #56
• Fix for issues where the undo shortcut key for flight plan was not working. Logbook and userpoint
  undo function now assigned to Ctrl+Shift+Z and Ctrl+Shift+Y to avoid overlap with flight plan
  undo/redo functions.
• Fixed issue where main window could not be resized below 1000 pixels. Minimum limit is now 300
  pixels. Shrinking the window too much can cause a garbled or overlapping display of dock windows.
• Map cache links in options and main menu now point directly to the correct sub-path map/earth.
• Added link to FltPlan site in airport information.
• Fixed several issues where buttons were not disabled in multi export options dialog on missing
  selection or empty route.
• Separated tab bar reset into a new menu item Reset Tabs to Default in menu Window. Window layout
  and and tabs can now be reset separately.
• Added option to reverse all mouse wheel functions in map and elevation profile in options dialog on
  page User Interface.
• Relaxed check for valid aircraft type to match ICAO types in aircraft performance.
• More small user interface fixes and improvements.

Build

• Moved version number to variable VERSION_NUMBER in file littlenavmap.pro instead of coding it
  into sources.
• Now writing files version.txt and revision.txt files into deployment folder allowing
  deployment scripts to automatically name archives. These files can be used to identify
  a version without opening the program.
