Answer:
Flight simulators are widely used for pilot training in the aviation industry, military pilot training, simulation of disasters or failures in flight, and aircraft development.
These simulations are used for pilot training, whose essential function is to train the crew in normal, abnormal and emergency procedures, before and during flight, practicing innumerable situations, such as: failures in electronic systems, loss of power, tailwinds and many others, which cannot be done safely with an aircraft in real situations. Explains to the new pilots the movements and attitudes of the ships, becoming a fundamental part of the training, saving lives and large economic losses.
These simulations allow knowing the causes of each plane crash in order to modify the operating procedures and training, so that its repetition is avoided. Flight safety investigations are complex and analyze numerous factors, and rather than investigating the persons responsible, it tries to find out the causes of the incident, considering human factors and technical issues.
