PC flight simulator programs have come a long way since Bruce Artwick published some magazine articles in 1979.
In fact, they have been adopted by several aerospace companies!
|1990s-Present||Elite||WM||FAA-approved, used by flight schools world-wide|
|2000||Microsoft Flight Simulator 2000||W||Evans & Sutherland Flight Simulators (rumor – their full-page ads resembled FS2000.) This division was sold to Rockwell Collins in 2006|
|2000s-Present||X-Plane||WML||Level 2 is FAA-approved, used by flight schools world-wide, also Garmin Avionics for ground laboratory|
|2000s-Present||FlightGear||WML||Open Source project, so used by many organizations and research departments. Rumored to be used by ATC.|
|2009-Present||Microsoft Flight Simulator 2006 (FSX) SP2 ESP||W||Lockheed Prepar3D available for $499 for non-entertainment use only.|
FSX is controversial in requiring the most powerful hardware to run with reasonable framerates due to using DX9 Shader 2. Also, all versions of FS200x exhibit minor stuttering in turns because of chronic bugs in loading and displaying scenery.
