If you’ve ever finished a flight in Microsoft Flight Simulator and immediately wondered how smooth your landing actually was, this small freeware utility might be for you. Arc – Aircraft Rating Calculator is a lightweight app that tracks your vertical speed and G-force at touchdown, giving you instant feedback with a clean on-screen overlay. It also logs each landing so you can track your progress over time. Beyond that, Arc adds a few extra touches like SimBrief OFP viewing, wind/runway visuals, and even a basic PA system for those who like to play the role of captain.
Available now on Flightsim.to, Arc is a lightweight Windows application that connects to MSFS 2020 or 2024 via SimConnect. It tracks your landings, shows runway wind conditions, lets you pull your SimBrief OFP for quick reference, and even gives you a public address system to make in-sim announcements.
At its core, Arc is a landing performance tracker. It monitors your vertical speed (FPM) and G-force on landing, overlaying that data on your simulator screen and logging it for later. There’s no complex setup required—just launch Arc, connect to the sim, and fly. After touchdown, you get your stats, which remain displayed until your next landing.
Arc also integrates with SimBrief to provide a simplified view of your latest OFP. Once you paste in your SimBrief ID, Arc fetches your most recent plan and displays relevant flight information: departure and arrival airports, block fuel, cruise level, cost index, and route.
This makes it easy to review key details before departure or reference them in flight, and once the flight is completed, you can save the entry to Arc’s built-in LogBook for future tracking.
Another useful feature is the wind/runway analyzer. Enter a METAR and select a runway, and Arc will generate a visual wind diagram showing the direction and strength relative to the runway. It’s a quick way to confirm your runway selection, especially at uncontrolled fields or when flying VFR.
Then there’s the Public Address system, which may not improve your landings, but will absolutely improve your immersion. You can assign a keybind, press the mic, and talk to your passengers just like a real airline captain. The PA audio plays directly in the sim. It’s a simple addition that adds a layer of roleplay many simmers will likely enjoy.
Arc is easy to install and works out of the box without the need for external dependencies. Just download, install, and connect. The interface is tab-based and intuitive, with each feature living in its own clearly marked section: Flight Plan, Status, Settings, LogBook, and more.
The developer, Mathéo, has also released a walkthrough video showing how everything works in practice.
Arc is available now, for free, through Flightsim.to.
