飛航管理使用衛星作為數據通訊、衛星導航與監視系統之基礎，提供了飛行員、航管單位及航空公司即時氣象與其他必需的數據。飛行員可以自由選擇最佳的航線飛行，節省航行時間與降低操作成本。縮減航機間的隔離，可以疏解航路的擁擠情形。採用自動化的管理系統可提升服務品質和降低工作人員的負荷。CNS/ATM 的實施將帶來航空運輸業更大的利益，不僅解決未來航空運輸業所帶來的問題同時也提高飛航服務品質與促進台灣對外的競爭力。 Following the development and the globalization of the economic, it is predicted by International Civil Aviation Organization (ICAO) that within two decades in the future, the capacity of transportation will increase two to three times more. In order to solve the future inflation of transportation issues, ICAO promoted a new aviation management system which developed the universal of CNS/ATM system for the unity of the global air traffic management by using satellite and digital technique for groundwork of the communication, the navigation, the surveillance and the air traffic management in 1989. It ensures supplying the safe, the rapid and the efficiency to the airspace environment and fulfills the demand of aviation transportation capacity in the future. This study collects the surrounding information around Taiwan to help establish the CNS/ATM system in the Taipei Flight Information Region. CNS/ATM will enable Taiwan to connect adjacent new air traffic management system and avoid different standard in different countries which could cause communication and coordination problem. CNS/ATM is developing in each country, with the goal that “Communication” is to develop the satellite communication;“Navigation” is to globalize the satellite navigation system that provides guidance on flight course; “Surveillance” is to monitor the process and report automatically. Air traffic management system is a satellite techni1quea that based on computer science and technology through the connection of satellite to supply air control center, pilot or Aviation Company with the data or voice message. That makes air traffic in order to ensure safety and efficiency in the airspace. Here offers fuzzy and grey theory on the air traffic flow control issue for ATM. This thesis is for analyzing and evaluating the benefit to supply the best sequence for the approach. Digital communication, satellite navigation and surveillance system based on satellite is used to air traffic management. Meteorology phenomenon and require data immediately provide the pilot, air control unit and airplane company. The pilot will be able to have the idea about the better route to save navigation time and deduct work cost. Reducing the gap between the airplanes can solve jam-packed airspace. An automatic management system enhances service quality and reduces staffs workload. CNS/ATM implementation will bring aviation transportation the better advantage, not only solve the congestion issues from transportation, but also exalt the service quality on aviation and increase the competitiveness of Taiwan to other countries.
