FlightGear

FlightGear is a free, open‑source flight simulator available for Windows, macOS and Linux. It provides a virtual environment where users can pilot a wide range of aircraft, from light general‑aviation planes to larger commercial jets, using realistic flight dynamics and visual scenery. The simulator includes a community‑maintained collection of aircraft models, airports, and weather systems, allowing users to practice navigation, instrument procedures, and emergency handling.

The software is targeted at aviation enthusiasts, student pilots, and hobbyists who want a cost‑free platform for flight training or casual flying. Its cross‑platform support and open‑source licensing enable users to customize the simulator, contribute new assets, or integrate additional tools without proprietary restrictions.

FlightGear is released in a stable maturity level and receives regular updates that introduce bug fixes and incremental features. Recent releases in 2024 and 2025 have added improvements to aircraft behavior, scenery rendering, and user interfaces, while the development team continues to engage with the community through blog posts and events such as FSWeekend.
