New Aviation Vehicles in the NextGen Environment: Procedures Design in Congested Terminal Airspace

Dupont, Matthieu

2014

The purpose of this study is to design new departure and arrival procedures for the SF Bay area Terminal Radar Approach Control in a NextGen environment with five anticipated new vehicles (very light jets (VLJ), cruise-efficient short take-off and landing (CESTOL), unmanned aircraft systems (UAS), civil tiltrotor (CTR), and supersonic transport (SST)), and to provide a foundation to assess the impact of developed procedures on the Bay Area air transportation system performance.

Methodology for Environmental Sustainability Evaluation Of Airport Development Alternatives

2013

This study develops a new approach for the evaluation of greener airport systems. The proposed concepts demonstrate how to implement greener practices from the early stages of an airport infrastructure project in an economically rational and stakeholder-focused manner. Objectives of the proposed methodology are two-fold: (1) to promote greener design practices among airport planners, designers, and managers, and (2) to institute active communication among all airport stakeholders. The study contributes to the state of the knowledge in airport environmental management by proposing the...

Economic Impact of a Lightning Strike–Induced Outage of Air Traffic Control Tower: Case Study of Baltimore–Washington International Airport

Ding, Wenzhe

2015

This research investigates how lightning strike–induced outages of airport infrastructure and facilities affect airport performance from an economic perspective, using Baltimore (Maryland)–Washington (D.C.) Thurgood Marshall International (BWI) Airport as a case study. On September 12, 2013, lightning struck within 300 m of the air traffic control (ATC) tower at BWI, causing injury and ATC tower and airport closures. The study findings reveal that the economic losses of the outage-related delays from that single event were almost five times higher than the ATC tower refurbishment that was...

Defining and Measuring Aircraft Delay and Airport Capacity Thresholds

TRB’s Airport Cooperative Research Program (ACRP) Report 104: Defining and Measuring Aircraft Delay and Airport Capacity Thresholds offers guidance to help airports understand, select, calculate, and report measures of delay and capacity. The report describes common metrics, identifies data sources, recommends metrics based on an airport’s needs, and suggests ways to potentially improve metrics.

Failures of Critical Systems at Airports: Impact on Aircraft Operations and Safety

Failures of critical systems at airports can significantly impact aircraft operations and cause substantial safety risks. This study develops a generalized method for measuring the impacts of unscheduled communication, navigation and surveillance systems outages on airport operational performance (i.e. throughput) and safety. The proposed method consists of two separate models – the aggregate and the disaggregate model. The aggregate model is a regression model that analyzes flight data, which are averaged per quarter hour and obtained from the Aviation System Performance Metrics database...

Characterizing Lightning-Strike Hazard to Airport Facilities: A Case Study of Baltimore Washington International Airport

As projections indicate, the U.S. National Airspace System (NAS) vulnerability to lightning strikes is growing due to increased severity and frequency of convective storms. Lightning hazards pose risks to personnel safety and may cause power outages, and therefore they can impact reliability and performance of the airport's facilities if they are not appropriately fortified. Although lightning-flash data with high temporal and spatial accuracy is available for the continental U.S., measuring airport facility lightning-induced outages remains challenging. Studies have shown that lightning-...

Selecting Climate Change Mitigation Strategies in Urban Areas Through Life Cycle Perspectives

Urban governments globally have generated climate change mitigation plans in recent decades. With greenhouse gases (GHG) being emitted from far-ranging anthropogenic sources, selecting mitigation alternatives from a portfolio of options can be highly challenging, particularly when capital budgets and life cycle costs are considered. This research combines life cycle assessment (LCA), life cycle cost accounting (LCCA), and mathematical formulation methods to select ideal alternatives for a case study city. We utilize LCA and LCCA to determine the environmental and economic costs associated...

Greenhouse Gas Emissions Mitigation Strategies within the Airport Sustainability Evaluation Process

2015

In recent years the aviation industry has initiated new sustainability efforts as a response to society's greater needs for living in healthier and more sustainable environments. Significant attention has been directed toward aircraft and their contribution to greenhouse gas emission. As we look at the aviation system more holistically, especially in the U.S., however, we discover a lack of comprehensive research addressing sustainability evaluation standards in airports. Sustainability, in a system as complex as an airport, can encompass many different areas such as water conservation,...
