Abstract
The introduction of new Air Traffic Management (ATM) concepts such as Trajectory Based Operations (TBO) may produce a significant impact in all performance areas, that is, safety, capacity, flight efficiency, and others. The performance framework in use today has been tailored to the operational needs of the current ATM system and must evolve to fulfill the new needs and challenges brought by the TBO content. This paper presents a novel performance assessment framework and methodology adapted to the TBO concept. This framework can assess the key performance areas (KPAs) of safety, capacity, and flight efficiency; equity and fairness are also considered in this research, in line with recent ATM trends. A case study is presented to show the applicability of the framework and to illustrate how some of the complex interdependencies among KPAs can be captured with the proposed approach. This case study explores the TBO concept of “strategic 4D trajectory deconfliction,” where the early separation tasks of 4D trajectories at multisector level are assessed. The framework presented in this paper could potentially support the target-setting and performance requirements identification that should be fulfilled in the future ATM system to ensure determined levels of performance.
Highlights
The Single European Sky (SES) High-Level Goals are Air Traffic Management (ATM) performance targets set by the European Commission with the support of the Single Sky Committee to steer the design and management of future ATM operations
As a contribution to the SES High-Level Goals, the Single European Sky ATM Research (SESAR) Concept of Operations [1, 2] is structured around the new concept of Trajectory Based Operations (TBO), which consists of a coordination of four dimensional trajectory predictions and executions subject to generic ATM constraints imposed across all involved operational stakeholders during the last 24 hours before flight arrival [3]
The resulting synthetized trajectories are used by the TBO model, which in this paper is represented by the STREAM algorithms (SA) module
Summary
The Single European Sky (SES) High-Level Goals are ATM performance targets set by the European Commission with the support of the Single Sky Committee to steer the design and management of future ATM operations. In 2005, the commission set four high-level performance goals for the SES to be met by 2020 and beyond: (1) achieve a 3-fold increase in capacity; (2) improve the safety by a factor of 10; (3) enable a 10% reduction in the effects that flights have on the environment; and (4) provide Air Traffic Management (ATM) services to the airspace users at a cost of at least 50% less. These overarching goals set the initial foundation of the SES initiative and, despite the evolution of aviation since 2005, they remain a valid reference in 2017 for assessing the performance of the ATM system in Europe. This consists of three layers, depending on the timeframe on which it applies: (a) strategic conflict management achieved through airspace organization and management, demand-capacity balancing, and traffic synchronization; (b) separation provision; and (c) collision avoidance
