2.2. Figure 2 shows the ATS route network in the SCS region. Figure 2. ATS Route Network in SCS Region 3. Data Sources 3.1. The data sources that have been used for the purpose of modelling and simulation are as follows: a) Air Traffic Data FlightGlobal INNOVATA* Traffic Period 01 Dec 2015 to 07 Dec 2015 (24 Hours Traffic for 7 days) b) Airspace Data Online Mapping and Aeronautical Charts Provider SkyVector c) Route Network Data Online Mapping and Aeronautical Charts Provider SkyVector d) Traffic Growth Rate Figures 6.5% CAGR for ASEAN Airbus Global Market Forecast 1 * Based on a random sample of 150 flights per day for 7 days, a comparison between INNOVATA and FlightStats was carried out. The percentage of flight cancellations per day was found to be approximately 2-3%. 2 P a g e
4. Modelling & Simulation 4.1 Introduction of SAAM Software 4.1.1. The modelling & simulation work was conducted with the use of SAAM. This tool was acquired from EUROCONTROL and they are currently using this as a tool for Modelling and Simulation. 4.1.2. SAAM is an integrated system for network-wide or local design, evaluation, analysis and display of air traffic, civil/military airspace and TMA scenarios. 4.1.3. SAAM is used for operational planning purposes to: a. Optimize strategic traffic flows; b. Design the route network and airspace; c. Analyze past and future traffic flows; and d. Display and compare projects. 4.2 SAAM Functionalities 4.2.1. SAAM offers a set of functions that could be used for the analysis of South China Sea air traffic. This section describes those functions with examples. a) Visualization of Traffic The traffic within SCS region was simulated in SAAM using traffic data from INNOVATA. Figure 3 below shows the traffic simulation for SCS region. Figure 3. Traffic Simulation for SCS Region 3 P a g e
SAAM provides the functionality to visualize traffic density. For example, Figure 4 shows the traffic density in SCS region. Such visualization functions depicts the utilization of routes in the SCS region. Figure 4. Traffic Density in SCS Region b) Entry Rate Analysis The Airspace Load Function provides the entry rate in any airspace and also gives an assessment of the amount of traffic within the specified airspace volumes. Figure 5 below provides an example of the hourly aircraft entry rate in the SCS airspace. Figure 5. Entry Rate Curve 4 P a g e
c) Scenario Economy The scenario economy function in SAAM can be used to compare length, time, fuel, CO2 and NOx emission of two traffic scenarios. This could be used in route optimization studies where a comparison between Before and After optimization can be made. The analysis results of route optimization potential could be studied in terms of: excess distance flown (NM), excess time flown (hours), excess fuel consumed (t), excess CO2 emitted (kg) and excess NOx emitted (kg) for each FIR in the SCS region. Table 1 shows an example of the Scenario Economy analysis on the SCS region.

5. Sample of Statistics on Air Traffic in SCS Region 5.1 Traffic on ATS Routes 5.1.1. The total number of flights per ATS route is calculated by SAAM using an advanced query function. It should be noted this calculation was based on the logic that any flights that enter the ATS route at any segment will be included to reflect the utilization of that route. 5.1.2. Table 2 depicts the number of flights for a sample of 15 ATS Routes from 01 December 2015 to 07 December 2015.

Sample of Statistics for flights within SCS from 01 Dec 2015 to 07 Dec 2015 5.1.3. In addition, the total number of flights for 7 days within the entire SCS region was 56,429. The least traffic was on 01 December 2015 (Tuesday) with 7,937 flights, and the most traffic was on 04 December 2015 (Friday) with 8,186 flights. 6 P a g e
5.2 Traffic in Airports 5.2.1. SAAM has the functionality to process consolidated traffic data to provide the total number of flight movements at each airport. A sample of the traffic movements for 20 airports, based on 04 December 2015, is provided in Table 3.

7 Conclusion 7.1. This report presents the capability of ATMRI using the SAAM tool to conduct various modelling and simulation of air traffic in SCS region. Such modelling and simulation enables a deeper analysis of the flow for current and future traffic. With and the availability of appropriate data, more comprehensive studies of the ATS routes in SCS could be undertaken to enhance airspace safety, efficiency and capacity in the region. References 1.
