Air traffic performance of the European air traffic system depends not only on traffic demand but also on airspace structure and its traffic distribution. These structural (airspace structure) and flow characteristics (factors such as traffic volume, climbing/descending traffic, mix of aircraft type, military area activity) influence airspace complexity, which can affect controller workload and influence the probability of safety occurrence. In other words, all these dynamic and static complexity components can potentially have an impact upon the safety of the air traffic management (ATM) system. Having in mind fluctuation in traffic on daily, seasonal or annual level in certain airspace, a few questions arise: How changes in traffic demand influence complexity and conflict risk? Is there any correlation between traffic demand, conflict risk and complexity? Are there any differences between seasons? For that purpose, an investigation is performed on FAB Europe Central (FABEC) airspace, based on two weeks of operated traffic during the summer and winter of 2017. Air traffic complexity is estimated using the EUROCONTROL complexity metrics, while conflict risk is assessed using the conflict risk assessment simulation tool. Results show that certain positive relationship exists between traffic demand, conflict risk and complexity.

In order to address the flight delays and risks associated with the forecasted increase in air traffic, there is a need to increase the capacity of air traffic management systems. This should be based on objective measurements of traffic situation complexity. In current air traffic complexity research, no simple means is available to integrate airspace and traffic flow characteristics. In this paper, we propose a new approach for the measurement of air traffic situation complexity. This approach considers the effects of both airspace and traffic flow and objectively quantifies air traffic situation complexity. Considering the aircraft, waypoints, and airways as nodes, and the complexity relationships among these nodes as edges, a dynamic weighted network is constructed. Air traffic situation complexity is defined as the sum of the weights of all edges in the network, and the relationships of complexity with some commonly used indices are statistically analyzed. The results indicate that the new complexity index is more accurate than traffic count and reflects the number of trajectory changes as well as the high-risk situations. Additionally, analysis of potential applications reveals that this new index contributes to achieving complexity-based management, which represents an efficient method for increasing airspace system capacity.

Navigasi penerbangan merupakan salah satu aspek penting dalam menciptakan keamanan dan keselamatan penerbangan. Indonesia saat ini telah mempunyai penyelenggara tunggal pelayanan navigasi penerbangan yaitu Air Nav Indonesia, yang mengelola 2Flight Information Region/FIR Indonesia Bagian Barat yang dikendalikan oleh JAATS dan FIR Indonesia Bagian Timur dikendalikan oleh Makassar Advance Air Traffic Services / MAATS. Penelitian ini dilakukan pada Air Navigasi cabang Bandara Sultan Mahmud Badaruddin II Palembang untukmengetahui bagaimana gambaran kesiapan JAATS dalam implementasi New Communication Navigation System/CNS dan Air Traffic Management/ATM ditinjau dari infrastruktur dan SDM professionalnya.Pengumpulan data dilakukan pada bulan Maret tahun 2014di LPPNPI/Air Navigation Indonesia Jakarta dan CabangAir Navigation Bandara Sultan Mahmud Badaruddin II-Palembang. Dari hasil pembahasan untuk mengantisipasi peningkatan jumlah pergerakan pesawat sampai dengan tahun 2030 melalui regresi linear diperlukan peningkatan infrastruktur dengan melakukan up grade peralatan dan sistem Aeronautica Information Services (AIS) dan meningkatkan Sumber Daya Manusia yang berkompetensi.Kata kunci: Navigasi,Air Nav Indonesia, Flight Information Region

Europe is moving towards a more closely integrated air traffic management system through the European ATC Harmonization and Integration Programme (EATCHIP). This paper explains the need for such an approach and how it was brought about by capacity limitations in the current European air traffic system. It describes the key strategy of progressive harmonization and integration by the various States, examines the roles of the European Civil Aviation Conference (ECAC), the International Civil Aviation Organization (ICAO), EUROCONTROL and the European Commission in the management of the Air Traffic Management (ATM) development programmes. It also reviews the longer-term planning of a future system with an enhanced relationship between the air and the ground, and addresses the navigation aspects of ATM systems.

Networked Next Generation Air Transportation System (NextGen) opened the gate to digital National Airspace System (NAS) in cyberspace. Air traffic improvements from NextGen system, accompanied by the risk of long-standing cyberattack issue in information technology industry became an increasingly challenging matter to the aviation community and Air Traffic Management (ATM), as cybersecurity challenges in the NextGen system could affect NextGen's principle assurance of safety and security in air transportation. The technological shift of NAS infrastructure from traditional radar-based systems to networking system of systems leads to a review, revision and redefinition of current policies, standards regelations, cultures and norm to reflect and mitigate new risks. Through analysing reports, regulations, standards, practices, recommendations from government and industry, the researchers analyse security impacts to NextGen; the risk of a cybersecurity incidents; and regulations to identify most effective and efficient control measures over information systems in ATM, and direction to further research.

The charter of FAA is to promote the safe, orderly, and expeditious use of the National Airspace System (NAS). To ensure that traffic flow is safe and efficient, FAA needs to know the expected traffic demand on the sector and the sector's capacity to accommodate that demand. When sector capacity is inadequate to meet the demand, congestion occurs. To ensure that safety is not compromised, FAA often takes action to reduce demand or increase capacity to avoid congestion. The MITRE Corporation's Center for Advanced Aviation System Development developed a time-on-task workload model to assess capacity and congestion in en route NAS sectors. A metric was developed and used along with the workload generated by the model and a workload threshold to estimate sector capacity. The metric, as constructed, enabled equitable comparison of capacity of different sectors, regardless of size. A field and lab evaluation of the workload model was used to quantify the model's task coverage and to calibrate its parameter values. The workload model was used to generate workload, capacity, and congestion profiles for selected en route sectors during good weather and during convective weather. The data used to generate the profiles can be used for various air traffic management applications.

Since 2010, air navigation service providers have been mandated to implement a positive and proactive safety culture based on shared beliefs, assumptions, and values regarding safety. This mandate raised the need to develop and validate a concept and tools to assess the level of safety culture in organizations. An initial set of 40 safety culture questions based on eight themes underwent psychometric validation. Principal component analysis was applied to data from 282 air traffic management staff, producing a five-factor model of informed culture, reporting and learning culture, just culture, and flexible culture, as well as management’s safety attitudes. This five-factor solution was validated across two different occupational groups and assessment dates (construct validity). Criterion validity was partly achieved by predicting safety-relevant behavior on the job through three out of five safety culture scores. Results indicated a nonlinear relationship with safety culture scales. Overall the proposed concept proved reliable and valid with respect to safety culture development, providing a robust foundation for managers, safety experts, and operational and safety researchers to measure and further improve the level of safety culture within the air traffic management context.
