What Does Flight Simulator Mean?
A flight simulator is a virtual reality system capable of simulating the environment of a flying machine for a pilot.

Techopedia Explains Flight Simulator
A flight simulator helps in artificially recreating the aircraft flight environment for pilot training, design or other purposes.The main purpose of a flight simulator is to help the pilot to achieve, test and maintain proficiency in handling airplane operation without involving any risk to property or lives, and at a much lower cost than training in the air. A simple flight simulator system consists of multiple displays, control devices, an audio system for communications and a computer system to process control inputs and record flight data.
