CESTOL Impact on U.S. Airport Network Operations

Cruise-Efficient Short Takeoff and Landing (CESTOL) is an aircraft design concept for future use to increase capacity and reduce emissions. The National Aeronautics and Space Administration (NASA) is investigating technological and operational concepts for CESTOL implementation in the U.S. National Airspace System (NAS). In support of NASA, we conducted a preliminary analysis of the potential impact on NAS-wide network traffic operations due to the introduction of CESTOL at selected major airports. These are the 34 domestic airports identified in the Federal Aviation Administration’s Operational Evolution Plan (OEP).

Unmanned Aircraft Research in Support of NextGen Trajectory Based Operations

The two predominately challenging issues facing the development of standards for Unmanned
Aircraft Systems (UAS) integration into the National Air Space (NAS) are collision avoidance and UAS command and contol link integrity. This paper discusses an approach for addressing the collision avoidance issues affecting UAS and shows how advances in this area can contribute to the advancement of the Next Generation Air Transportation System (NextGen).

Departure Taxi Time Predictions Using ASDE-X Surveillance Data

Accurate prediction of departure taxi times will help airlines to proactively manage push-times, to optimally assign scarce ramp resources, and to propagate delay information to destination airports in a more timely fashion. Air Traffic Control (ATC) will benefit via improved demand forecasts for the terminal area and enroute air sectors. An ancillary benefit to such predictions is the ability to discern factors contributing to longer taxi times.

Objective and Automatic Estimation of Excess Taxi-Times

As the price of fuel continues to rise, airlines are increasingly seeking innovative ways to reduce fuel consumption. One solution is to reduce excess taxi-time resulting from holds on the airport surface. While it is implausible to eliminate all holding (especially during times of
high runway utilization), a detailed analysis of holding on a track-by-track basis allows
stakeholders to identify and quantify the excess fuel associated with specific issues (e.g.,
summaries by airport, runway, carrier, aircraft type, etc.). A track is the time-ordered position
data for a flight as it taxis.

A New Modeling Capability for Airport Surface Traffic Analysis

This paper describes work to enhance the existing Surface Traffic Limitations function of the
NASA Advanced Concept Evaluations System (ACES) Build 4.6 to support more detailed analysis of future concepts for airport surface operations. This ACES-based Surface Traffic Limitations Enhancement (STLE) computerized simulation function is a platform for evaluating current and alternative future Air Traffic Management (ATM) concepts of operation, such as those being considered by NASA’s NextGen Airspace and Airportal projects.

ASDE-X and NextGen Total Airport Management Operations

The NextGen initiative is defining new concepts for operating and managing air traffic into and out of the busiest U.S. airports. The impetus for these efforts include accommodating air traffic demand projections, the move to trajectory-based air and surface operations, methods for maximizing the efficiency and utility of existing runway, taxiway and gate infrastructures, the need to reduce operational costs per aircraft and vehicle movement, and the desire to abate or mitigate airport noise and missions.
