Windows 95 and Windows NT 4.0 operating systems. Flight Simulator 2002 − Released in October 2001 Flight Simulator 2002 (version 8.0), abbreviated as FS2002, improved vastly over previous versions. In addition to improved graphics, FS2002 introduced air traffic control (ATC) and artificial intelligence (AI) aircraft enabling users to fly alongside computer-controlled aircraft and communicate with airports. An option for a target framerate was added, enabling a cap on the framerate to reduce stutter while performing texture loading and other maintenance tasks. In addition, the 3D Virtual Cockpit feature from FS98 was re-added in a vastly improved form, creating in effect a view of the cockpit from the viewpoint of a real pilot. The external view also featured an inertia effect, inducing an illusion of movement in a realistic physical environment. The simulation runs smoother than Flight Simulator 2000, even on comparable hardware. A free copy of Fighter Ace 2 was also included with the software. Flight Simulator 2004: A Century of Flight − Released in July 2003 Flight Simulator 2004: A Century of Flight (version 9.0), also known as FS9 or FS2004, was shipped with several historical aircraft such as the Wright Flyer, Ford Tri-Motor, and the Douglas DC-3 to commemorate the 100th anniversary of the Wright Brothers' first flight. The program included an improved weather engine that provided true three-dimensional clouds and true localized weather conditions for the first time. The engine also allowed users to download weather information from actual weather stations, allowing the simulator to synchronize the weather with the real world. Other enhancements from the previous version included better ATC communications, GPS equipment, interactive virtual cockpits, and more variety in autogen such as barns, street lights, silos, etc. Flight Simulator 2004 is also the last version to include and feature Meigs Field as its default airport. The airport was closed on March 30, 2003, and the airport was removed in the subsequent releases. It is also the last version to support Windows 98/9x series of operating systems. Flight Simulator X − Released in October 2006 Flight Simulator X (version 10.0), abbreviated as FSX, is the tenth edition in the Flight Simulator franchise. It features new aircraft, improved multiplayer support, including the ability for two players to fly a single plane, and players to occupy a control tower available in the Deluxe Edition, and improved scenery with higher resolution ground textures. FSX includes fewer aircraft than FS2004,
