The FlightGear Flight Simulator Project Is An Open-source, Multi-platform, Cooperative Flight Simulator Development Project. Source Code For The Entire Project Is Available And Licensed Under The GNU General Public License.
The Goal Of The FlightGear Project Is To Create A Sophisticated Flight Simulator Framework For Use In Research Or Academic Environments, For The Development And Pursuit Of Other Interesting Flight Simulation Ideas, And As An End-user Application. We Are Developing A Sophisticated, Open Simulation Framework That Can Be Expanded And Improved Upon By Anyone Interested In Contributintor Out Old Airplane Parts, To University Research And Instructional Use, To Simply Having A Viable Alternative To Commercial PC Simulators.
Flight Gear And Its Source Code Have Intentionally Been Kept Open, Available, And Free. In Doing So, We Are Able To Take Advantage Of The Efforts Of Tremendously Talented People From Around The World. Contrast This With The Traditional Approach Of Commercial Software Vendors, Who Are Limited By The Collective Ability Of The People They Can Hire And Pay. Our Approach Brings Its Own Unique Challenges And Difficulties, But We Are Confident (and Other Similarly Structured Projects Have Demonstrated) That In The Long Run We Can Outclass The Commercial "competition."
