Flights across the world increases in number annually. Consequently, traffic movement in airspace increases accordingly, affecting the probability of conflict among aircrafts. Manoeuvre must be undertaken to avoid conflicts, by means of conflict resolution. In general, conflict resolution application is done qualitatively by Air Traffic Control (ATC), purposely done to circumvent inter-aircraft separation that may cause accidents. Precursory detection models and conflict resolution had been carried out with their own respective scope of research and method. This research paper discusses development of air traffic management in a broader sense covering aircraft modelling, conflict detection modelling, and conflict resolution modelling at airway merging point. The models are integrated into a single model to acquire a finer understanding regarding the effects of applying a variety of conflict resolution towards the separation beyond the merging point. Validation is conducted by modelling arrival in Soekarno-Hatta International Airport and comparing the results with preceding studies. Subsequently, the validation is done by visualizing aircraft position when simulation is ran, performed to comprehend the correspondence of aircraft’s movement and position to its designed route. Conflict resolution is implemented in this research to obtain separation result, impact of separation result due to various resolutions in relation to detection distance, aircraft variables and aircraft resolution. Angle between merging point influences resolution decision making, wherein resolution decision making relies on range and meeting point among each aircraft. Time spent executing resolution begets different separation value for each resolution.
