飞行仿真器或飞行仿真机〈香港称为仿真驾驶舱〉是一种尽可能真实地再现或仿真航空器驾驶感觉的系统。飞行仿真器包含了从电子游戏，到由液压或电动机驱动，并由最先进的电脑技术所控制的同比例仿真驾驶舱。

飞行仿真器已广泛地运用于由航空工业设计和研发，以及为民用和军用飞机做飞行员与机组成员培训。

工程飞行仿真器也于用航空器制造商用于以下任务：

A flight simulator is a device that artificially re-creates aircraft flight and the environment in which it flies, for pilot training, design, or other purposes. It includes replicating the equations that govern how aircraft fly, how they react to applications of flight controls, the effects of other aircraft systems, and how the aircraft reacts to external factors such as air density, turbulence, wind shear, cloud, precipitation, etc. Flight simulation is used for a variety of reasons, including flight training (mainly of pilots), the design and development of the aircraft itself, and research into aircraft characteristics and control handling qualities.
