How albar965/littlenavmap works

Little Navmap is a desktop flight-planning and navigation application for flight simulators. The central workflow is to load simulator and navigation data, search for locations and procedures, assemble and calculate a flight plan, then inspect it on the moving map and export it. Major companion capabilities include airport information, weather and online traffic, aircraft performance, logbook recording, user-defined map features, and a web interface. The graph combines README-described features with sampled query, route, performance, and controller behavior; some subsystem wiring is therefore intentionally not shown.
