A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation.
Microsoft Flight Simulator is a series of amateur flight simulator programs for Microsoft Windows operating systems, and earlier for MS-DOS and Classic Mac OS. It is one of the longest-running, best-known, iconic, and most comprehensive home flight simulator programs on the market. It was an early product in the Microsoft application portfolio and differed significantly from Microsoft's other software, which was largely business-oriented. Due to celebrate its 40-year anniversary in November 2022, Microsoft's Flight Simulator is the longest-running software product line for Microsoft, predating Windows by three years. Microsoft Flight Simulator is one of the longest-running PC video game series of all time.
Orbiter is a space flight simulator program developed to simulate spaceflight using realistic Newtonian physics. The simulator was released on 27 November 2000; the latest edition, labeled "Orbiter 2016", was released on 30 August 2016, the first new version of the simulator since 2010.
A train simulator is a computer based simulation of rail transport operations. They are generally large complicated software packages modeling a 3D virtual reality world implemented both as commercial trainers, and consumer computer game software with 'play modes' which lets the user interact by stepping inside the virtual world. Because of the near view modeling, often at speed, train simulator software is generally far more complicated and difficult software to write and implement than flight simulator programs.
Simulated racing or racing simulation, commonly known as simply sim racing, are the collective terms for racing game software that attempts to accurately simulate auto racing, complete with real-world variables such as fuel usage, damage, tire wear and grip, and suspension settings. To be competitive in sim racing, a driver must understand all aspects of car handling that make real-world racing so difficult, such as threshold braking, how to maintain control of a car as the tires lose traction, and how properly to enter and exit a turn without sacrificing speed. It is this level of difficulty that distinguishes sim racing from arcade racing-style driving games where real-world variables are taken out of the equation and the principal objective is to create a sense of speed as opposed to a sense of realism.
Driving simulators are used for entertainment as well as in training of driver's education courses taught in educational institutions and private businesses. They are also used for research purposes in the area of human factors and medical research, to monitor driver behavior, performance, and attention and in the car industry to design and evaluate new vehicles or new advanced driver assistance systems.
Virtual Air Traffic Simulation Network (VATSIM) is a nonprofit organization that operates an online flight-simulation network noted for its active membership and realism. Users are able to fly aircraft as a pilot, or direct traffic as an air traffic controller in what has been described as a close approximation of real-life aviation procedures.
Combat flight simulators are vehicle simulation games, amateur flight simulation computer programs used to simulate military aircraft and their operations. These are distinct from dedicated flight simulators used for professional pilot and military flight training which consist of realistic physical recreations of the actual aircraft cockpit, often with a full-motion platform.
Falcon 4.0: Allied Force (F4AF) is an F-16 based combat flight simulator released by Lead Pursuit in 2005. The game is based around a realistic simulation of the Block 50/52 F-16 Fighting Falcon in a series of missions in the Balkans.
Virtual Sailor, created by Ilan Papini and published by Quality Simulations and Hangsim, is a shareware program which allows users to operate a wide variety of vessels in world-wide locations. Both the graphics and boat dynamics have been designed to be as realistic as possible, and the software also features multi-player capabilities. Users can create add-ons including boats, sceneries and marine animals to share with other players.
RailDriver is a desktop cab controller for train simulation software. It replaces keyboard and mouse operation as far as possible to provide a more realistic train driving experience. It is designed to be compatible with Microsoft Train Simulator. N3V's Trainz, BVE Trainsim and World of Subways also support RailDriver. As of December 2020, Dovetail Games' Train Sim World 2 added an open beta for Raildriver on PC. Other software may be controlled using downloadable resources.
Rig'n'Roll is an open world truck driving simulation and racing video game released on 27 November 2009 in Russia and during 2010 in the rest of the world. It simulates truck driving and management along with associated business strategic activities, and features North American trucks. The game takes place in California and Nevada, in the year 2014.
Microsoft Flight Simulator X is a 2006 flight simulation video game originally developed by Aces Game Studio and published by Microsoft Game Studios for Microsoft Windows. It is the sequel to Microsoft Flight Simulator 2004 and the tenth installment of the Microsoft Flight Simulator series, which was first released in 1982. It is built on an upgraded graphics rendering engine, showcasing DirectX 10 features in Windows Vista and was marketed by Microsoft as the most important technological milestone in the series at the time. FSX is the first version in the series to be released on DVD media.
A maritime simulator or ship simulator is a system that simulates ships and maritime environments for training, research and other purposes. Today, simulator training given by maritime schools and academies is part of the basic training of maritime professionals.
Vehicle simulation games are a genre of video games which attempt to provide the player with a realistic interpretation of operating various kinds of vehicles. This includes automobiles, aircraft, watercraft, spacecraft, military vehicles, and a variety of other vehicles. The main challenge is to master driving and steering the vehicle from the perspective of the pilot or driver, with most games adding another challenge such as racing or fighting rival vehicles. Games are often divided based on realism, with some games including more realistic physics and challenges such as fuel management.
Digital Combat Simulator, or DCS, is a combat flight simulation game developed primarily by Eagle Dynamics and The Fighter Collection.
A space flight simulation is a genre of flight simulator video games that lets players experience space flight to varying degrees of realism. Common mechanics include space exploration, space trade and space combat.
Amateur flight simulation refers to the simulation of various aspects of flight or the flight environment for purposes other than flight training or aircraft development. A significant community of simulation enthusiasts is supported by several commercial software packages, as well as commercial and homebuilt hardware. Open-source software that is used by the Aerospace industry like FlightGear, whose flight dynamics engine (JSBSim) is used in a 2015 NASA benchmark to judge new simulation code to space industry standards, is also available for amateur use. A popular type of amateur flight simulators are combat flight simulators, which simulate combat air operations from the pilot and crew's point of view. Combat flight simulation titles are more numerous than civilian flight simulators due to variety of subject matter available and market demand.
Farming Simulator is a farming simulation video game series developed by GIANTS Software. The locations are based on American and European environments. Players are able to farm, breed livestock, grow crops and sell assets created from farming.
