However, due to the large differences in the equipment structure, it is impossible to simulate the hydraulic operation in the actual emergency process, which does not conform to professional operating procedures and habits. Long-term use of incorrect training methods cannot produce correct conditioned reflex processing to complete the steering operation judgment of the rudder plate in actual emergencies.
