# Core Competency Quantitative Evaluation of Air Traffic Controller in Multi-Post Mode
## 1 Introduction  
With the rapid development of air transportation, the safety of air traffic operation has been put forward very high requirements. Air traffic management (ATM) has the characteristics of high strength, high risk, and high load. The ability level of air traffic controllers (ATCO) is one of the most essential and complex factors [1]. How to make a practical qualitative and quantitative evaluation of the ATCOs' ability and quality, accurately find out the unfavorable factors affecting the safety of air traffic operation, and make effective adjustments in time to avoid the risk of ATM operation, and rationally allocate team resources are the fundamental theoretical and practical problems that need to be studied and analyzed in the field of aviation human factors [2]. Establishing a scientific and reasonable quantitative evaluation method for the ability and quality of ATCOs, grasping the performance and development trend of their working ability and working status, and adjusting the allocation of team resources in time will help the dynamic improvement of the ability and quality of controllers. It is significant to improve the safety efficiency of control operation, expand air traffic flow, and ensure flight safety. In this paper, the main objective of the scientific study is to achieve multiple classifications and construct an assessment model of ATCO ability, then quantify the ATCO ability in multi-post mode, and finally analyze the fit degree of ATCO between ability and post quantitatively. Based on this, domestic and foreign scholars have gradually deepened the research on the evaluation of ATCOs' ability, extending from the concept of \"skill\" to the level of \"competency\" [3], and successively researched the ATCO competency evaluation model, combined with relevant business scenarios, taking the qualitative and quantitative analysis of ATCOs' ability, professional level, and knowledge application [4]. In 2005, by referring to the internationally accepted research methods of competency framework for professional management and technical personnel [5; 6], [PERSON] et al., developed an initial ATCO competency framework [7] for capacity assessment and job training [8]. The International Civil Aviation Organization (ICAO), the Federal Aviation Administration (FAA), and the European Organization for the Safety of Air Navigation (EUROCONTROL) have also researched the competency characteristics of ATCOs and applied them to training and evaluation, etc. [9]. In 2016, based on the research of [PERSON] et al., ICAO updated the \"Training Manual\" (ICAO DOC 9868) [10], through extensive questionnaire survey and analysis, proposed a relatively complete ATCO competency framework, and initially introduced the competency characteristics and performance behavior indexes. Based on the competency framework, [PERSON] conducted research and application of training for military ATCOs [11]. At the same time, the FAA issued a \"Control Job Training Teaching/Evaluation Manual\" [12], described the competency of controllers, and proposed 23 secondary indexes from 6 dimensions. [PERSON] et al. [13] proposed 15 secondary indexes from 3 dimensions of individual, organization, and psychology around the ability assessment of controllers. Although a relatively mature ATCO competency framework has been formed abroad, it does not directly apply to China's national conditions and ATM status quo. Because the framework does not address the specific definition of duties, sharing of tasks, ratings, and proficiency levels existing in the organization, which should be adapted to the local context of the organization and the professional experience of ATCOs [10]. It is necessary to design a special adaptive model according to the specific situation within the organization, otherwise, the application effect will not be ideal.
