The invention relates to a paratrooper parachuting training simulator and a method thereof. The paratrooper parachuting training simulator comprises a supporting frame, an ascending ladder, a jumpingplatform, a control system, a linear motion mechanism, a harness system, a liftable landing platform, a virtual reality device, a fan device and a software system; through a pressure sensor, the software system is triggered to perfectly simulate plane leaving; through the control system, the software system is triggered to perfectly simulate free falling and parachute opening, and true touch feeling is generated through the linear motion mechanism and the fan device; through the liftable landing platform, the landing process is simulated, and all the parachuting processes are simulated. Through the simulation of all the parachuting processes, the training effect is better compared with partial simulating training.
