The invention relates to a universal flight simulator based on virtual operation, which comprises footstools, a throttle lever, a steering column and a sound blending box arranged in a universal concept cabin of the virtual operation; the universal concept cabin also comprises a sight display system consisting of a back projection system, a virtual switch, a knob and a virtual instrument operated by using a touch mode, a displaying and resolving center for model resolving, flight control resolving and acceleration resolving and a buffeting chair seated by a driver. The universal flight simulator based on virtual operation uses a virtual operation switch and the virtual instrument to replace a real physical hardware switch and an instrument and can flexibly switch the virtual switch, the instrument software and a flight control model into various models for flight training and games. The universal flight simulator is small in size, light in weight, convenient to disassemble and assemble and suitable for use under the ordinary office condition, has vivid simulation, low price and strong universality through switching models by software and can be combined to a simulator set with different models for confronting training and games after being connected to the Internet.
