The Next Generation Air Transportation System (NextGen) is a congressionally mandated initiative to modernize the U.S. air traffic control system through satellite-based technologies that can increase the precision of aircraft flight paths, radar displays, and operating times, improving capacity, efficiency, predictability, flexibility, environmental effects, and safety. Several critical milestones have been achieved, but the long time frame for implementation raises challenges.

Optimal Time Advance in Terminal Area Arrivals: Throughput vs. Fuel Savings

The current operational practice in scheduling air traffic arriving at an airport is to adjust flight schedules by delay, i.e. a postponement of an aircraft's arrival at a scheduled location, to manage safely the FAA-mandated separation constraints between aircraft. To meet the observed and forecast growth in traffic demand, however, the practice of time advance (speeding up an aircraft toward a scheduled location) is envisioned for future operations as a practice additional to delay. Time advance has two potential advantages. The first is the capability to minimize, or at least reduce,...

An Analysis of Air Traffic Controller-Pilot Miscommunication in the NextGen Environment

2013

This paper extends research on miscommunication between air traffic controllers and pilots by developing statistical models that predict the outcome of communications within the scope of controller-pilot data communications in the Next Generation Air Transportation environment. A database of controller-pilot voice messages from high and super-high altitude en-route sectors of US airspace is investigated. Emphasis is given to parameters that can be utilized in the voice-only communication, as well as in the mixed media, environment. This allows formulation of reasonable assumptions about...

We developed a method that combines engineering metrics and human factors in the NextGen environment to provide the results about the system performances. This method can further be generalized and applied to other NextGen components, especially to System Wide Information Management (SWIM) and Federal Telecommunications Infrastructure (FTI).

Sustainability Feasibility: A Framework for Greenhouse Gas Emissions Mitigation for Midsized U.S. Airports

Monsalud, Andrew
Ho, Denny

2013

In recent years a significant amount of research has been conducted with the objective of improving efficiency of aircraft operations through optimized aircraft trajectories, thereby reducing harmful greenhouse gas (GHG) emissions such as CO2. However, as we look at the aviation system more holistically, we discover that there is a serious lack of comprehensive research that addresses reduction of GHG emissions at airports. Although the need for reduction in airport GHG emissions clearly exists, only a few US state or federal policies require airport operators to reduce such...

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...
