The transportation sector, accounting for about one fifth of all greenhouse gas emissions, is facing a significant transformation in order to become more climate-friendly. In terms of air transportation, there are several important steps on the way to making flying sustainable both for the planet itself and for people directly or indirectly being exposed to its effects. In the state of the current air traffic operations, where environmentally friendly propulsion systems and fuels are not yet implemented on a large scale, enhancing the efficiency in the airspace can help to bring us closer to the environmental goals of aviation. Such solutions may include improved synchronization of arriving flights in the Terminal Maneuvering Area (TMA), in which congestion is a problem for many airports. In this thesis, we first explore and develop methodologies for assessing the environmental impact of the operations in TMA. More specifically, the goal of the assessments is to quantify the additional fuel consumption, gaseous emissions and noise that comes from horizontally and vertically inefficient arrival operations in TMA. We perform our assessments on a couple of European airports, including Stockholm-Arlanda. Secondly, we propose a Mixed Integer Programming (MIP)-based optimization model which provides for conflict-free arrival operations, where aircraft fly fuel-efficient Continuous Descent Operations (CDOs), applied to Point Merge (PM) arrival procedures, with the primary purpose to serve as a route assigner. We base our optimization on real scenarios, from actual transmitted flight data, and model realistic descent profiles considering the operational capabilities of the specific aircraft type. Additionally, the optimization model ensures the required spacing between aircraft taking off and landing in case the runway is used in a mixed mode. We evaluate our solutions by assessing numerous performance metrics, including environmental efficiency, and compare to the actual trajectories of the real operations. On two European airports implementing PM procedures, we demonstrate that our optimization model provides improved vertical performance as well as reduced time and distance flown in TMA, contributing to reduced levels of noise and fuel savings, accompanied by decreased emissions.

The objective of this research is to investigate the tradeoff between operating cost and environmental acceptability of commercial aircraft. This involves optimizing the aircraft design and mission to minimize operating cost while constraining exterior noise and emissions. Growth in air traffic and airport neighboring communities has resulted in increased pressure to severely penalize airlines that do not meet strict local noise and emissions requirements. As a result, environmental concerns have become potent driving forces in commercial aviation. Traditionally, aircraft have been first designed to meet performance and cost goals, and adjusted to satisfy the environmental requirements at given airports. The focus of the present study is to determine the feasibility of including noise and emissions constraints in the early design of the aircraft and mission. This paper introduces the design tool and results from a case study involving a 250-passenger airliner. Antoine, Nicolas and Kroo, Ilan M. Langley Research Center

The Next Generation Air Transportation System (NextGen) refers to the federal programs (predominately airspace, air traffic, or avionics related) that are designed to modernize the National Airspace System (NAS). The Airport Cooperative Research Program's (ACRP's) NextGen initiative aims to inform airport operators about some of these programs and how the enabling practices, data, and technologies resulting from them will affect airports and change how they operate. Volume 1, Understanding the airport's role in performance-based navigation : resource guide, provides comprehensive information to practitioners concerning all aspects of Performance-Based Navigation (PBN) and how implementation affects overall airport operations. This Resource Guide encompasses background information, description of effects on short- and long-term airport development, impacts on safety and performance measures, and other critical factors affecting future airport operations. In addition to providing guidance to users on available resources for additional assistance, this volume also includes lessons learned and best practices based on findings from case studies that examined the airport operator's role in PBN implementation. Volume 2, Engaging airport stakeholders : guidebook, helps airports engage the U.S. Federal Aviation Administration (FAA), aircraft operators, community representatives, and other airport stakeholders during the planning, environmental review, design, deployment, and monitoring phases of NextGen implementation. The guidance references a NextGen Outreach Toolkit, which contain videos, an interactive flow chart, and links to additional resources. The NextGen Outreach Toolkit, which will be available for download from a forthcoming website, accompanies Volume 2. The Toolkit also incorporates material created in conjunction with the other projects in the ACRP 150 (NextGen) series. These materials may help airports establish a continuous engagement strategy to balance stakeholder needs as well as efficient NextGen implementation. Volume 3, Resources for airports, is a resource guide that provides a comprehensive list of NextGen technologies and initiatives categorized and described for airport practitioners, and presents existing Federal Aviation Administration (FAA) plans that could potentially affect airports of all sizes and roles, the larger aviation industry, and the public. This guide presents a likely timeline for implementation and highlights the FAA's planned rollout of near- and mid-term elements as well as its long-range vision. Appendices include a glossary of terms and a Public Information Toolkit for communicating about the NextGen initiative to the broad spectrum of external stakeholders. This Public Information Toolkit is also available at the ACRP NextGen for Airports. Volume 4, Leveraging NextGen spatial data to benefit airports : guidebook, provides information for airport operators on the creation, maintenance, and use of spatial data that is generated as a result of NextGen initiatives. The data that airports have or will have to produce is used in a variety of different ways to advance some of the NextGen programs. This guidebook identifies benefits to airports from the spatial data that is required or produced from NextGen programs, not all of which are obvious. The guidebook also describes costs, and financial and legal considerations. In addition, a customizable presentation template can be downloaded from the report webpage at www.trb.org/acrp. The presentation can be tailored to educate various communities about NextGen and spatial data.
