The red flag military exercise is for actual combat

These training programs of the US Air Force Tactical Command have greatly changed the training culture and values of the Air Force. Before 1975, the slogan of Air Force training in peacetime was "Flight safety is paramount", but after the appearance of "Red Flag" and other exercises, the slogan of Air Force changed-"How to fight in wartime, how to practice in peacetime"

Today, with the highly developed computer technology, computer flight simulation and virtual reality technology can create a very realistic simulated flight environment, and at the same time, the US military also has the most powerful computing power and coverage in the world. Pilots can experience more real flight environment and multi-aircraft cooperative operations in the simulator, and can practice weapons operation and aircraft troubleshooting and other subjects. However, various characteristics of real flight, such as overload, psychological stress and physical changes of pilots, cannot be simulated by any calculation. For example, when a pilot makes an instrument blind descent or lands on an aircraft carrier, his heart rate is usually as high as 1 to 14 beats per minute, but even on the most realistic simulator, the pilot's heart rate is only 8 to 12 at most when performing such flight operations. Different psychological pressures often produce completely different results in air combat. Therefore, it can be asserted that computer simulation can never replace real flight training and actual combat exercises.
