Project Overview：

　　Airspace capacity is one of the important factors to grasp airport capacity increase of Taiwan, and there must be a special tool to conduct analysis for this purpose. The current foreign software packages such as SIMMOD, TAAM, etc., easily need to spend hundreds of thousands to nearly 10 million (NTD) to purchase, and the expense is very high but the system function may not fully meet the airspace management requirements for Taiwan. In addition, the core technology is totally controlled by the manufacturer, and additional expenses may be required to pay when new functions are needed. Based on this, in order to explore and analyze the airspace capacity of Taiwan, it is necessary to build a simulation model that conforms to our airspace characteristics, to simulate the operation of airspace aircraft, and to improve the research energy of independent analysis of civil aviation capacity for our country.

Research Outcomes：

(1)Completed the terminal control area simulation: The system composed the operation status of the aircraft in the three-dimensional space by plane (latitude and longitude position) and elevation information.

(2)Completed of the airside and apron simulation of Taoyuan Airport: The system can microscopically display the operation status of the aircrafts on the Taoyuan International Airport surface, including the departure and arrival of aircraft, and the status of aircraft tow, as well as the display of occupancy status of aprons.

(3)Simulation Verification Results: Airports often uses the number of aircraft that can take off and land per unit time as an important indicator of capacity. Therefore, this research collected the numbers of aircraft that take off and land every hour during a simulation, and compared those with the number of aircraft actually landing at and departing from Taoyuan International Airport every hour of the day of June 30, 2017 . During the actual entire day, the maximum number of arrivals in 1 hour was 29 flights, and the maximum number of departure in 1 hour was 30 flights, and the maximum number was 43 flights in 1 hour when combining both departures and arrivals. The system simulation results showed that the maximum number of arrivals was 24 flights in 1 hour, the maximum number of department was 27 flights in 1 hour, and the maximum number was 46 flights in 1 hour when combining both departures and arrivals. The simulation results displayed were close to the actual situation.

Promotion of Outcomes and Benefits ：

• This Research has completed the basic theoretical analysis of airspace simulation, initially grasped the important components and key parameters of the civil aviation airspace capacity analysis, and established a prototype simulation model. The promotion of research outcomes and benefits are as follows:
  • A paper of outcomes was submitted to the Quarterly Journal of Transportation Planning in December 2017, as a reference for all sectors.
  • A paper title "Innovative Development of Decision-making Support Tools for Air and Sea Transportation" was presented at a Symposium in May 2018, for all sectors to understand the specific outcomes of research in airspace simulation by this Institute.
  • The research outcomes were presented at an internal conference of the Ministry of Transportation and Communications in June 2018, for the Minister and heads officials of agencies to understand the research outcomes of airspace simulation by this Institute.
  • A symposium was held with experts to discuss and clarify the model's simulation effectiveness in November 2018.
