A certain squadron of the Southern Theater Command Navy actively creates a training atmosphere that tolerates mistakes and allows trial and error - organizing officers and soldiers who dare to tolerate mistakes and innovate in the southern spring, with warm winds blowing gently. Several drones swept over the top of the head, breaking the tranquility of the sky. In a drone flight competition held by a naval squadron in the Southern Theater Command, flight controller Wang Hao operated the drone to continuously complete actions such as fixed-point hovering and tracking flight, landing first, and ultimately winning the championship with the shortest time and most stable operation. "The operation method I adopted has been independently optimized." As I walked off the field, Wang Hao told his comrades, "To achieve good results, scientific training according to operating standards is important, but it also needs to be continuously optimized and improved based on the actual task. In this process, the team established a fault-tolerant mechanism, encouraging us to boldly try and make mistakes and challenge our limits during training, which increased everyone's enthusiasm for war and research." Later, he talked about a previous experience. In that drone flight test mission, Wang Hao controlled the drone to fly smoothly according to the established flight trajectory and completed multiple test projects. As they were preparing to return, a strong wind suddenly struck and blew the drone onto the rocks. "It's broken!" Wang Hao's heart tightened as the plane landed. "Faced with unexpected situations, Wang Hao promptly and calmly dealt with them. The drone did not cause serious damage and will not be held responsible." At the summary meeting of the experiment, the team leader announced the decision to handle the situation. Without waiting for criticism and blame, Wang Hao firmly said, "The organization has created a positive and inclusive training environment for us. We need to work harder to improve our professional skills and strengthen our ability to win!" When it comes to fault tolerance mechanisms, senior engineer Qing Ping of the brigade felt deeply touched: "Currently, more and more new equipment is being installed in the army. If there is no fault tolerance mechanism and no trial and error opportunities are given, it is easy for officers and soldiers to be timid during training, leading to a negative mentality of 'doing more, doing less, and making less'." This realization is not without a reason. In the early stage of the formation of the drone team, Qingping was the main person in charge, actively coordinating relevant professional talents and technical backbone, conducting discussions and exchanges around equipment performance, equipment structure principles, and talent training models, and colliding many "golden ideas" that are conducive to improving training quality and efficiency. Insufficient collection of flight parameters in complex environments and uncertainty of critical values for some equipment... After a period of time, many problems that existed during training have not been effectively solved, which has left Qing Ping, who was originally full of confidence, somewhat confused. During a casual conversation, Qingping heard some concerns from some officers and soldiers. "Because I am not familiar with the performance of new equipment for the first time, I feel uncertain when operating it, fearing that I may accidentally damage the 'baby bumps'." There are risks in equipment testing, and if I fall off the plane, it will waste training resources, and I am afraid of being criticized and held accountable. "" Flowers and fruits grow, and a suitable soil environment is needed, so does the growth of officers and soldiers. "Qingping deeply feels that only by creating a training atmosphere that tolerates mistakes and allows trial and error, can officers and soldiers unload their ideological" burdens "and boldly strive, focus on research and skill training, and the new equipment can form combat effectiveness as soon as possible.". So he reported the relevant situation to the party committee of the brigade. On the basis of thorough research and argumentation, it is necessary to explore the construction of a set of fault-tolerant and corrective measures
