Turbulence in the comment cabin

Flight Planning with Little Navmap

Flight sim fans are obsessed with this free planner and dragging subscriptions while they’re at it

TLDR: Little Navmap is a free tool for planning routes in flight simulator games, and the blog shows how it works with X-Plane on a high-end PC. But commenters made the bigger point: this is the kind of capable, no-subscription software that turns a niche hobby into a puzzle-loving, proudly anti-paywall fan movement.

A blog post about Little Navmap could have been a dry tour of buttons and menus, but the real action is in the crowd response. The software itself is a free, open-source tool that helps people plan pretend flights in games like Microsoft Flight Simulator and X-Plane, and the author shows it running on a very brag-worthy monster PC before mapping routes from Estonia. Nice setup, sure — but commenters immediately turned the story into something much juicier: a love letter to nerdy joy, old-school skill, and software that doesn’t try to bill you every month forever.

The strongest opinion by far? This isn’t just a map app — it’s a brain game. One commenter basically said flight planning is for people who want the thrill of solving geometry puzzles without needing a math degree, which is such an unexpectedly wholesome flex it nearly stole the whole post. Another swooped in with peak tablet-parent energy to say the app even works beautifully on an iPad through a built-in web page, turning the vibe from “desktop hobby” to “cockpit command center.”

And then came the mini culture war: one fan praised Little Navmap as a refreshing example of software that values capability over subscription lock-in, which reads like a direct subtweet of half the modern software industry. No giant flame war erupted, but the mood was clear: commenters are tired of being milked, thrilled by useful tools, and maybe just a tiny bit smug that this free app seems to do so much. In other words, the community didn’t just like this software — they treated it like a small rebellion with maps.

Key Points

  • Little Navmap is presented as an open source flight planner that supports simulators including X-Plane and Microsoft Flight Simulator.
  • The article says the project was started by Alexander Barthel about ten years ago and is built from roughly 120,000 lines of C++ using Qt5, OpenGL, D3D, and SQLite3.
  • Little Navmap’s map functionality relies heavily on KDE’s Marble, and the GitHub repository had 119 open issues and 992 closed issues at the time of writing.
  • The author documents the workstation used for the walkthrough, including an AMD Ryzen 9 9950X CPU, 96 GB RAM, Crucial T700 SSD, Nvidia GTX 1080 GPU, and Windows 11 Pro.
  • The setup walkthrough covers importing X-Plane aviation databases, enabling Little XConnect, switching to dark theme and spherical projection, and starting a flight in X-Plane 12 from Lennart Meri Airport in Tallinn using a Cirrus SR-22T G6.
