Table 5: Adapted multi-dimensional core competency model in multi-post mode. resolution, and the ACC post model mainly focuses on the competency dimension of \(F_{1}\) Situational awareness. 2. The content of the model is the composition of the secondary indexes of each dimension, which is basically about 28 items. The model of the APP post contains up to thirty items, and the TWR model contains only 26 items. The number of secondary indexes is ranked as APP > General > ACC > TWR, which is consistent with the order of command difficulty coefficient and workload of various posts. 3. The competency indexes of each model are consistent with the multi-post competency needs analyzed in Table 2. The competency index content of the General post model is relatively balanced, taking into account the seven dimensions. The significant competency requirements of TWR, APP, and ACC posts are non-routine situations management abilities (\(x_{22}\), \(x_{23}\)), accurate separation and conflict resolution abilities in complex situations (\(x_{11}\), \(x_{12}\), \(x_{13}\), \(x_{14}\), \(x_{15}\), \(x_{16}\)), and the abilities to discover potential flight conflicts and resolve risks (\(x_{11}\), \(x_{12}\), \(x_{13}\), \(x_{14}\), \(x_{24}\), \(x_{25}\)), which are reflected in various core competency models and constitute an important part of the model.
