Little Navmap is a free open source flight planner, navigation tool, moving map, airport search and airport information system for Flight Simulator X, Prepar3D, Microsoft Flight Simulator 2020 and X-Plane and is available for Windows, Apple macOS and Linux.
Little Navmap comes with a detailed manual also including tutorials which is available online as well as in PDF and other formats like EPUB. Help buttons in all relevant areas of the program display corresponding chapters in the online manual on click.
A widely configurable map display using the OpenStreetMap as a background map which is only one option of many online and included offline maps. The map shows airports, navaids, airways, airspaces, oceanic tracks, high altitude winds, AI or multiplayer aircraft and ships as well as airport weather, winds aloft and a minimum off-route altitude grid (MORA). A seamlessly integrated airport diagram displays taxiways, displaced thresholds, overrun areas, aprons, parking spots and more.
User can place airport traffic patterns or holdings as a visual guidance on the map.
It supports approach and departure procedures like SIDs, STARs, custom final approaches, offers a widely configurable automatic flight plan calculation and several export formats like GFP (Reality XP GTN and Flight1 GTN), FPL (Reality XP GNS), GPX, RTE, FLP and X-Plane FMS as well as drag and drop flight plan editing on the map. The program can read the PLN, FMS and FLP and more flight plan formats.
Several flight plan formats can be exported using the flight plan multiexport feature with one click.
Keyboard shortcuts help to access most functions without mouse.
An elevation profile is shown for the flight plan allowing to find a safe cruise altitude also displaying top of climb, top of descent and procedure altitude restrictions. Calculated and shown climb as well as descent paths adhere to altitude restrictions.
Aircraft performance and fuel planning is included which automatically considers winds aloft for fuel, top of climb and top of descent calculation. Performance values can be collected automatically during flight and can be merged into the currently profile at any time.
Search functionality allows to look for airports, navaids, procedures, user defined waypoints and logbook entries by a large amount of criteria also including a spatial search.
Userpoint functionality allow to place, edit and export user defined features like points of interest, visual reporting points and more on the map. Import and export of CSV, X-Plane and Garmin files.
Little Navmap comes with its own logbook allowing to automatically record, search and edit logbook entries. The logbook records the flight plan and the flown track which can be exported to GPX files.
Oceanic and other tracks like NAT can be downloaded, shown on the map and can be used for automatic flight plan calculation.
The program can generate an ATS route description from flight plans and vice versa where the output is widely configurable.
A cycle 1801 database courtesy of Navigraph is included in the download and includes navaids, airways, airspaces, procedures and more. The navigation data can be updated by the Navigraph FMS Data Manager.
Display of clients and centers of VATSIM, IVAO, PilotEdge and custom online networks.
Little Navmap features its own internal web server which allows to follow aircraft progress from any device across a network.
