Heinz Erzberger and co-authors receive the Kenneth Harris James Prize
May 3, 2013

The paper, “Automated Conflict Resolution, Arrival Management, and Weather Avoidance for Air Traffic Management,” authored by Heinz Erzberger, Todd Lauderdale, and Yung-Cheng Chu, which was recently published in the Journal of Aerospace Engineering (August 2012), was selected for the Kenneth Harris James Prize by the Institution of Mechanical Engineers' Aerospace Division, a professional engineering organization in the United Kingdom. This year the Prize honors the best paper on an aerospace subject published in the Journal in 2012. The certificate for the Prize and a cash award will be given on May 14, 2013 in London, England. The paper describes three algorithms to address separation conflicts, arrival management, and weather avoidance, and how they can be integrated in automated separation assurance. The paper was first presented at the 27th International Congress of the Aeronautical Sciences 2010 in Nice, France. A part of the algorithm described in the paper has been incorporated into the Dynamic Weather Reroute system that NASA and American Airlines are currently evaluating in operational tests.

The Effectiveness of Incentivizing ADS-B Equipage Through Preferential Merging:
May 3, 2013

Preferential Merge Re-sequencing is a “best-equipped best-served” air traffic management policy meant to accelerate the adoption of Automatic Dependent Surveillance-Broadcast (ADS-B) Out by giving an operational incentive to airlines, to invest in upgrading their fleet. Preferential Merge Re-sequencing is accomplished by re-sequencing the arrival order at en-route merge-fixes, favoring high-equipped aircraft over low-equipped aircraft, thus reducing flight time for high-equipped aircraft. In this study, Preferential Merge Re-sequencing was simulated using historical data for flights into Phoenix Sky Harbor International Airport, focusing on a benefit analysis for nationwide as well as regional airlines. Final results from this study will be presented at the 2013 AIAA Aviation Conference in August of 2013. (POC: Noam Almog, Olga Agafonova)

Air and Space Traffic Management Workshop
May 3, 2013

A technical workshop on integrated air and space traffic management was held at Ames Research Center on April 18, 2013. The workshop attracted over 25 participants, including 12 FAA personnel representing NextGen, Commercial Space Transportation, Command Center, and Technical Center. Other organizations participating in the workshop were Stanford University, Florida Tech, Cal Poly, Air Force Research Lab, and NASA Ames Research Center. The briefings covered various aspects of air and space traffic integration: NextGen vision/goals, current operational practices/constraints, and analyses of future operational concepts/technologies. Current operational practice is very conservative because it requires large time/space reservations to protect air traffic from a variety of possible spacecraft malfunction scenarios. There was consensus among workshop participants that NextGen operations should provide equitable sharing of airspace resources by issuing air traffic restrictions strategically based on the nominal spacecraft trajectory and then imposing additional tactical restrictions only as required in the event of an actual spacecraft malfunction. Accomplishing this goal will require an integrated set of real-time technologies for spacecraft trajectory information-sharing, spacecraft debris envelope computation, and decision support for issuing aircraft reroute/hold advisories. Participants from NASA, FAA, and Stanford agreed to coordinate their work going forward and share relevant tools/data. (POC: Karl Bilimoria)
