Frequent flights have made Taipei Terminal Control Area (TCA) into flow congestion and conflict threat to two close airports. A flow monitor is proposed to provide the predicted sequence of inbound and outbound aircraft with minimum separation in the intersected 10 nautical miles airport circles in Taipei TCA. The repetitive flight plans (RFP) from flight data processor (FDP) data are applied to estimate the time of metering fix until landing. Air traffic control (ATC) indicates vectoring aircraft according to predict sequence by executing ground holding and speed adjustment to avoid airborne holding or conflict. Based on daily schedules and their RFP, flow monitor is designed to forecast the next 60 minutes of inbound flights and to ease possible congestion within 30 minutes in Taipei TCA. Dynamic rescheduling is applied to change delay flights in flow queuing periodically. A case study is simulated to focus on current flow condition. The flow monitor can be used in approach control region and can efficiently reduce the probability of congestion in the busy TCA.
