Quantitative Research on the Complexity of Pilot Operation Procedures Based on TACOM Method

Pilot Operation Procedures (POP, Pilot Operation Procedures) are the basic operating rules that pilots must follow during flight [1]. The quantitative evaluation of expected operating behaviors in standard operating procedures is particularly important [2]. In this paper, the TACOM method is used to establish a complex measurement dimension of POP and form a system of quantified flight standard operating procedures. The task complexity is divided into five dimensions: step information complexity, step logic complexity, step number complexity, system knowledge complexity, and decision-making complexity, to construct relatively comprehensive conditions for measuring the complexity of flight standard operating procedures. Taking the Cessna 172 standard operating procedure as an example, the task step decomposition, graph theory construction, weight investigation, and quantitative solution are carried out in the four processes from landing to shutdown. The final scores for each process are landing: 1.4087, go-around: 1.3426, after landing: 1.4937, stop: 1.9275. Then, 15 pilots with Cessna-related flight experience were subjectively investigated through the method of ordering relation [3]. The final scores in each stage were landing: 2.0788, go-around: 2.0156, post-landing: 2.1787, and stop: 2.2154. The objective score has a better correspondence. The effectiveness and usability of this method in pop complex quantification are verified. This research innovatively applies the TACOM method to the quantitative evaluation of flight standard operating procedures in the aviation field, which has strong research value and practical significance.
