New Features

New Features New Menu Items New Context Menu Items

Elevation Profile

New New New
  • Added scrolling and zooming ability to elevation profile. Elevation profile now has a context menu also including Show on Map and more functions.
    Added splitter to elevation profile dock window which has sliders for zooming vertically and horizontally. These can be hidden by dragging the splitter to the right.
    Zooming can also be done using mouse wheel (Wheel+Shift for vertical zooming).
    Added keyboard navigation using cursor keys and numpad keys for zooming and scrolling.
    Panning in elevation profile with mouse click and moving like in map. Double click zooms to position on map. #34
  • Elevation profile now uses same aircraft icon as map. Changed elevation profile to completely adhere to map painting settings like line width, text size and symbol size. Profile display now hides flight plan if hidden on map. #298
  • Adjusted elevation profile to display passed, active, straight-in and circle-to-land flight plan legs in the same colors like the flight plan on the map. Navaid symbols are now shown on the descending or ascending line. #298
  • Added option to display ILS and VASI slopes in elevation profile if an approach is selected. Menu items allow to disable these. #299
  • Added calculation and display for top of climb to elevation profile display. Calculation based on aircraft performance data.
  • Now showing procedure altitude restrictions in profile display.
  • Top of descent is calculated considering altitude restrictions of approach or STAR. Same for top of climb and SID. All legs after and at the FAF and FACF points are forced to minimum altitude to avoid arriving above ILS glideslope.
  • Display of Above Ground Altitude on top label in profile window follows climb and descent slope instead of using cruise altitude.
  • Giving clear error indication if cruise altitude is too high (i.e. TOC and TOC overlap) or if restrictions are violated due to too low cruise altitude.
  • Removed barely visible highlight on map when hovering cursor above elevation profile. Highlight colors can now be customized in little_navmap_mapstyle.ini. Mouse position in elevation profile is now shown with a cyan/black circle on the map. #34
  • Jump back to aircraft functionality added in elevation profile. Uses the same settings as the map. #34
  • Fixed display color of profile labels for night mode. Removed all dark profile colors and pens from little_navmap_mapstyle.ini. Using OS and style colors now. #34
  • Solved problems where aircraft in elevation profile jumped to wrong leg or moved backwards.
  • Aircraft track is now ignored when determining profile window altitude to avoid confusion when stale tracks result in wrong profile maximum.
  • Aircraft direction now turned if reversal relative to active leg detected.
  • Fixed several issues with aircraft movement and trail in elevation profile. Profile trail now depends on active leg and is now saved separately from aircraft trail on map.

Aircraft Performance


See main menu -> Aircraft and tab Aircraft in dock window Flight plan.

Note that the new tab in the Flight plan dock window is meant for fuel planning and does not change during flight (except when collecting performance data).

  • Added aircraft performance facilities including edit dialog, new, save, save as, load, file history and report.
    Performance files (lnmperf) can be dragged into the main window of Little Navmap to load.
    Added main menu Aircraft and tab on flight plan dock window for loading, saving and editing of performance files.
  • Performance and fuel calculation can use an average cruise wind setting where wind is interpolated for climb and descent for calculation.
  • Added automatic aircraft performance calculation option during flight (Aircraft -> Collect Performance for Flight).
  • A default performance profile with 3 NM / 1000 ft descent and climb rules and no fuel consumption is default.
  • Flight plan table shows both fuel weight and volume in separate columns.
  • Window title now shows aircraft performance file name additionally to flight plan file and change state indicated by *.
  • URLs are recognized in aircraft performance description and can be opened there. Local file and directory links (e.g. file:///C:/Projekte/atools or file:///home/alex/) as well as web URLs are recognized and opened.

  • Added Insert Flight Plan menu item into flight plan table context menu. Added Append Flight Plan menu item into flight plan table context menu.
  • Now selecting and highlighting imported legs after inserting or appending flight plan. #264
  • Now displaying FAF, IAF, FACF and MAP in the procedure preview, flight plan table and tooltips. #196
  • FAF and/or FACF is shown with a Maltese cross on the map and in elevation profile. The Maltese cross is applied to either final approach fix or final approach course fix depending on ILS GS intercept altitude and approach type. #196
  • Changed last Proceed to Runway leg to correct Circle to Land for approaches without runway ends and Straight In for others.
  • Circle-to-land and straight-in legs following a missed approach point are now drawn correctly with a dashed line on the map and in the flight plan profile. #252
  • Added indication for DME distance to or from waypoint in procedure search (e.g. TAU+6) and flight plan table for certain leg types.
    This minimizes the confusing duplicate display of idents in the flight plan table. #265
  • Added procedure name to flight plan table instead of the generic names like SID or STAR.
  • Added display of ARINC name (e.g. Q21 or I16) to flight plan header label since some FMCs need this value. #306
  • Added warning dialog for flight plan zero cruise altitude before saving. #263
  • Made loading of procedures more tolerant for renamed runways and for ARINC names of procedures.
  • Removed annoying change in flight plan when Little Navmap adapted start position on loading. Now leaving flight plan change status unchanged.
  • Disabled export of approach procedures for Flight Factor airbus since required data is unknown.
  • Fixed issue with missing runway in X-Plane FMS files having circle-to-land approaches. X-Plane can now load these type of approaches without error message.

  • Added saving of altitudes for X-Plane FMS formats which will show up for each waypoint in the stock FMS now.
  • Fixed issue in route description generator which omitted SID and STAR when no intermediate waypoints were present.
  • Flight plan table now displays localizer frequencies for approaches.
  • Moved FMS 3 format to export sub-menu since it became less important.


  • Now loading procedures partially from a flight plan if some could not be found.
  • Better error report on procedure loading issues. Now showing the procedure names which cannot be found in the database.
  • Fixed several drawing and other issues with procedures.
  • Added workaround for 3-letter airport idents in procedures which were not recognized and showed an error in the procedure search (red procedure leg).


New New
  • Added mouse click and modifier options for quick access. Doing a second click on the hot spot of a shown feature like range rings or measurement lines removes it. #268
    • Shift+Click: Add or remove range rings or navaid range ring.
    • Ctrl+Click: Start rhumb-line measurement or delete measurement line.
    • Alt+Click: Start great circle line measurement or delete measurement line.
    • Ctrl+Shift+Click: Add or edit userpoint.
    • Ctrl+Alt+Click: Insert point into nearest flight plan leg.
    • Shift+Alt+Click: Append point to flight plan.
  • Added Shift+Wheel and key combinations for zooming in small steps. See legend for a list of keys.
  • Added minimum off route altitude (MORA) data one degree grid display to map. Data coming from Navigraph (also from the included database cycle 1801). See main menu -> View -> Show Minimum Altitude. #84
  • Added extra airport display layer in map that shows runways and runway numbers before airport diagram shows up. #308
  • Fixed several problems for aircraft and next waypoint centering mode. Updates are now triggered by a timer depending on speed and distance to waypoint. Minimum zoom distance is now a function of altitude above ground.
    See dialog Options on tab Simulator Aircraft: Allow scrolling ... and Jump back ....
  • Centering of active flight plan leg and aircraft (if enabled in options) falls back to simple aircraft centering if distance to flight plan is larger than 50 NM.
    This helps to avoid situations where the program zoomed too far out when flying with stale flight plans.
  • Changed jump-back-to-aircraft logic to avoid weird behavior (zooming far out and other issues).
    When aircraft is on ground or Center map on aircraft and next flight plan waypoint is not selected:
    • Start looking around on the map by moving first (mouse drag or cursor keys) and not by zooming (mouse wheel or plus and minus keys) to suppress aircraft centering for a while.
    • Zooming without movement (drag or cursor keys only) keeps the zoom distance.
  • Added option to avoid blurred online maps. This is enabled per default. See dialog Options on tab Map: Avoid blurred .... This options works best with the map projection Mercator. #254
  • Added option for sun shading on map which can use real time, simulator time or user defined time. See main menu View -> Show Sun Shading and Sun Shading sub-menu.
    Shading darkness can be adjusted in dialog Options on tab Map Display: Sun shading ....
  • Added dialog to set user defined time and date for sun shading. See main menu View -> Sun Shading -> Set user defined time. #60
  • Drawing of complex X-Plane airports accelerated significantly. #245
  • Added dashed center line to ILS feathers and made feathers semi-transparent.
  • ILS labels now adhere to the text background color setting for navaids. This allows to select a white background for the labels for better visibility.
  • Now omitting curves, arcs, holds, procedure turns and other fancy geometry of procedures on high zoom factors to avoid a mess up of graphics in the spherical projection. Fixed flight plan leg distance label turning into weird directions when using spherical projection and at high zoom factors. #287
  • Aircraft icon heading is now more correct at higher zoom levels when using spherical projection. #239
  • Improved zooming when using a touchpad. Now less sensitive when using two finger touchpad or other gestures.
  • Added workaround for issues when zooming to map objects. Now determining the best zoom distance until all is visible.
  • Fixed issue of map jumping to the wrong place when zooming around the anti-meridian with the mouse wheel.
  • Changed map context menu to correctly show only the mentioned item in Show information menu item and nothing else.
  • Replaced home view symbol on map with actual icon from toolbar button.
  • Moved Remove all Ranges, Measurements and Patterns from all context menus to main menu Map.
  • Several issues with the map context menu and Show Information fixed.
  • Fixed several drawing issues with the aircraft trail, procedures on high zoom levels, flight plan, ILS and others.
  • Replaced OpenMapSurfer hillshading with the one used for OpenStreetMap since server is offline.

  • Added option to disable map window undocking in options dialog on tab Map.
    Allowing to undock the map window (option checked - default) can cause issues when resizing dock windows or the main window.
    Uncheck this option if you see strange or annoying resizing behavior when changing dock window or main window sizes.
    In some cases the dock window might also freeze, i.e. docks cannot be resized. Uncheck this option if you see one of these issues.
  • Reset window layout now also changes window size and centers window to avoid messed up layouts. Changed default layout to avoid locked elevation profile size.
  • Disabled restoring of full screen mode on macOS since Qt freezes dock windows.
    If that happens double click the title bar of any dock window to float it. Double click again to dock it back and you can resize all docks again.
  • Now always showing version in main window title. Development versions also show Git revision. #304
  • Added Copy Map Image to Clipboard function in file menu.
  • Now appending date and time suffix to map screenshot name to avoid overwriting for Save Map as Image.
  • Added warning dialog when using the buggy and limited online elevation data.
  • Added information dialog for Navigraph only scenery mode. #262
