## What it is
Little Navmap is a free open-source desktop flight planner, navigation tool, moving map, and airport information system for flight simulators including FSX, Prepar3D, MSFS 2020/2024, and X-Plane 11/12. It loads stock and add-on simulator data to render detailed navigation maps with airways, procedures, airspaces, and online map themes.

## Use cases
- plan VFR and IFR flight routes for X-Plane or MSFS
- view a moving map of my aircraft position during a flight simulator session
- search airports and view detailed airport information and charts
- display SID, STAR and approach procedures from simulator navdata
- load and edit flight plans in PLN and other formats
- show airspaces and navaids on an offline navigation map
- connect to Flight Simulator X or Prepar3D via SimConnect for live tracking

## When to choose
- you fly FSX, Prepar3D, MSFS 2020/2024, or X-Plane and need a free desktop flight planner
- you want a moving map that follows your simulator aircraft in real time
- you need airport, navaid, and procedure information from stock or add-on simulator data without third-party subscriptions
- you want offline maps plus optional online themes like OpenStreetMap

## When to avoid
- you need real-world certified aviation navigation data for actual flying - this is for simulator use only
- you want a web-based or mobile planner rather than a desktop application
- you fly simulators other than the supported FSX/P3D/MSFS/X-Plane family
