“…For example, implementing RNAV SIDs at ATL resulted in tighter patterns for the departures and subsequently allowed arrival aircraft a greater choice of routes (Helfrick, 2015). Similarly, RNAV SID trials at SJC showed that a 12.5% reduction in inter-flight spacing resulted in a 45% improvement in total en route transitions' capacity (Timar, Hunter, & Post, 2013).…”

Performance-based Navigation (PBN) allows aviation operations to be conducted based on actual operational requirements rather than the requirements of ground-based equipment. Although the general operational benefits of PBN procedures have been recognized by various studies, there is a need to specify the actual benefits in terms of the frequency of event anomalies that could be expected from the use of PBN procedures. The study reviewed some of the available literature and identified some operational improvements as reported by previous authors. The study then proceeded to review archival data from the Aviation Safety Reporting System (ASRS) database with a view to identifying the link between the use of PBN procedures and reported event anomalies. Overall, there were significantly fewer reported event anomalies when PBN procedures were used than when PBN procedures were not used. It is suggested that air operators and air navigation service providers conduct appropriate risk and safety assessments in their consideration of an increased use of PBN procedures.

“…Various applications in this area [55][56][57][58][59] are summarized in Table A3. MacWilliams and Proter [55] demonstrated the use of relative position criterion (RPC) to project actual aircraft route within the qualification region, and deliver and sequence the aircrafts to runway by merging multiple flows into a single flow.…”

“…In addition, the flight path prediction was improved and the self-reported controller workload was reduced. Timar et al [57] assessed RNAV's standard instrument departure (SID) and standard terminal arrival (STAR) procedures under PBN. They used a generic sequencing model to capture SID/STAR inefficiency and mitigation mechanism using a case study in Northern California, United States.…”

Traditional design approaches in civil engineering mainly focus on codes/guidelines related to building an infrastructure, while performance-based analysis (PBA), an emerging new reality around the world, focuses on the performance of the end product. Professional organizations, academicians, and the industry have made significant contributions in formulating PBA in various civil engineering fields, where practical guidelines and principles have been adopted in infrastructure analysis. This paper presents a critical review of PBA applications in three civil engineering fields: transportation, environmental, and structural engineering. The applications are grouped into a wide array of civil engineering areas, including highway transportation, pavement design and management, air transportation, water-structures design and operation, landfill design, building architectural design for evacuation, urban energy design, building earthquake-based design, building wind-based design, and bridge design and management. A total of 187 publications on PBA were reviewed and details on 122 application papers (from 23 countries/regions) are presented. The review consists of vertical and horizontal scans of PBA applications. In the vertical scan, the applications in each civil engineering area are summarized in tabular format that shows the system element modeled, analysis objective, performance criteria, analytical tool, and specifications/codes. The horizontal scan (discussion and lessons learned) addresses the following aspects of PBA: (1) the wide array of analytical tools used, (2) the broad functional and process-related areas, (3) the advantages, challenges, and opportunities, and (4) potential future applications. It is hoped that the state-of-the-art review presented in this paper will help researchers/practitioners quickly find useful information about PBA and promote its development in their respective fields.

“…The benefits of metroplexes have been investigated and assessed by several studies. Some generic models have been formulated to assess the potential impacts of a metroplex in addressing its inefficiencies by spatial and temporal approaches [3] [4]. To capture more detail and a more realistic environment, a generic model was extended and adjusted to a specific metroplex or by using simulation tools such as Airport and Airspace Delay Simulation (SIMMOD) to simulate operation conditions.…”

“…To capture more detail and a more realistic environment, a generic model was extended and adjusted to a specific metroplex or by using simulation tools such as Airport and Airspace Delay Simulation (SIMMOD) to simulate operation conditions. The results of this research show that by decoupling the Standard Instrument Departure (SID) existing fixes and Standard Terminal Arrival (STAR) entry fixes, adjusting temporal arrival scheduling, and adding an additional en-route transition can improve throughput and reduce arrival delay [3]. Using more precise and accurate satellite-based navigation with than a legacy navigational system, metroplexes are capable of making the airspace more efficient with less queueing delay and more throughput.…”

A key component of the goals of the Next Generation Air Transportation System (NextGen) is to safely improve the efficiency of the National Airspace System (NAS) by enhancing inefficiency in metroplexes. Based on the use of precise satellitebased navigation, Time Based Flow Management (TBFM), and other advanced techniques and tools, the benefits of a metroplex have been identified through research, indicating that it is capable of making airspace more efficient with less queueing delay and more throughput. However, those studies focused only on operations in normal weather conditions; special weather conditions such as convection were not considered. This study investigated the quantitative impacts of a metroplex under representative operation conditions in convection. Investigations included identification of representative convective weather conditions, analysis of historical radar tracking data in a postmetroplex period, development of queuing system-based models of Terminal Radar Approach Control (TRACON) facility arrival operations with and without metroplex for the North Texas Metroplex, and simulations to evaluate airspace performance in terms of TRACON throughput and arrival delays. Simulation analyses showed an average 27% increase in TRACON throughput at a peak of 15 minutes, as well as 2.39 minutes saved per arrival flight at Dallas/Fort Worth International (DFW) and 1.65 minutes saved per arrival flight at and Dallas Love Field (DAL) when a metroplex is implemented in heavy demand. The increase in TRACON throughput and arrival time saved by a metroplex climbs as traffic grows; however, the increase reaches a limit when the amount of traffic reaches a certain point.
