Flight simulation refers to the use of computer software and hardware to recreate the experience of piloting an aircraft. This can include simulating the various systems and controls of the aircraft, as well as the environment in which the aircraft is flying, such as the weather, terrain, and other factors. Flight simulation is used for a variety of purposes, including training pilots, testing new aircraft designs, and providing a platform for virtual aviation enthusiasts to fly and experience different aircraft and scenarios. Flight simulators can range from simple programs that run on a computer to highly advanced systems that use specialized hardware and software to create a realistic and immersive experience.
