FlyByWire Simulations is an open-source development collective that emerged from the flight-simulation community to deliver high-fidelity aircraft add-ons for Microsoft Flight Simulator 2020. Focused on systems depth and cockpit authenticity, the group re-engineers default airframes into study-level machines, most notably the freeware Airbus A32NX, whose custom fly-by-wire logic, detailed FMS, and failure modeling appeal to virtual airline pilots, cockpit-builders, and training captains who demand real-world procedural accuracy. Complementing the aircraft, the publisher maintains the FlyByWire Installer, a lightweight desktop client that streamlines downloading, updating, and toggling modular packages such as simBrief integration, custom sounds, or experimental development branches without manual file juggling. Typical use cases include IFR practice with full LNAV/VNAV, multi-crew shared-cockpit events, and hardware-in-the-loop setups that feed home-built CDUs or MCP panels through extensive LVAR and HVAR exposure. Because everything is built under an open-source license, users can also fork the code, contribute systems like hydraulic or electrical simulations, and push nightly builds back to the community. The publisher’s software is available for free on get.nero.com, where downloads are served through trusted Windows package sources such as winget, always pull the latest stable or experimental versions, and support batch installation of multiple FlyByWire components in one command.
