An Analysis of En Route Wake Turbulence Behavior Based on In-Flight Measurements
Rocio Frej Vitalle, CSSI, Inc.

The recent incident involving the encounter of an Airbus A380 wake vortex by a Challenger 604 has drawn attention to the potential hazard of wake vortices en route. To broaden the understanding of the risks associated with en route vortex systems, the FAA, in collaboration with the National Research Council of Canada (NRC), has collected high-altitude wake turbulence data. An analysis of wake vortex fields based on such in-flight measurements has shown that wake turbulence may exist at distances well beyond minimum separation. The strength of these vortices, as well as transport and decay rates, was found to be highly dependent on atmospheric conditions. A study of historical weather data provided herein suggests that the likelihood for atmospheric conditions that trigger a wake encounter increases as longitudinal separations are reduced. Implementing wake mitigation strategies may allow increasing NAS capacity without compromising safety. As track separation increases, altitude changes or lateral offsets are discussed as potential mitigations that may be useful in avoiding wake turbulence.

Airborne Trajectory Management (ABTM): A Blueprint for Greater Autonomy in Air Traffic Management
Capt. William B. Cotton, National Institute of Aerospace
David Wing, NASA Langley Research Center

All classes of airspace users experience constraints to their flight operations that, in varying degrees, prevent them from accomplishing their "business case" flight trajectory in an efficient or cost effective manner. In fact, the NAS has been designed to best accommodate the airline user with a manual system for managing traffic that has evolved around ground-based control within airspace sectors. This model has kept air transportation very safe and moving remarkably well, but it depends on rigid structuring of the airspace and traffic flows to maintain safety, often at the expense of efficiency, and for many new airspace users, the ability to operate at all. A system for Airborne Trajectory Management (ABTM) is proposed offering greater flight efficiency in a series of steps that coincide with NextGen technology upgrades in the NAS. Beginning with en route optimization of route and altitude, later ABTM steps incorporate Data Comm, time-based arrivals, and ultimately traffic separation in first a strategic and then a full tactical sense. Coordination with conventional ATC is continuous throughout, and first adopters achieve increasing flight benefits with each step of implementation, beginning with TASAR, the Traffic Aware Strategic Aircrew Requests tool, in the Electronic Flight Bag.

Introducing Data Model Standards for DataComm Information Exchange over SWIM
Charles Chen & Antonio Correas, Skymantics, LLC

ATC services use datalink communication systems such as FANS/ACARS, FAA DCIS, and EUROCONTROL DLS/Link2000+ [using dedicated Communication Service Provider (CSP) networks such as Rockwell Collins (ARINC) and SITA]. A need has been identified in the broader aviation community for sharing up-to date status information of ATC instructions and clearances with stakeholders. To efficiently disseminate this information, SWIM can be utilized to publish an XML-based data format and leverage existing publish/subscribe schemes. SWIM architecture can support the dissemination of the data and handle governance of the information to authorized users. However, a standard data model for this information is not yet specified. Introducing new “XM,” called Datalink Messaging Exchange Model (DMXM), for datalink information sharing can ensure alignment with current international SWIM development efforts at the ICAO level.

    Hon. Linda Hall Daschle Named 2018 Glen A. Gilbert Memorial Award Winner

    The Air Traffic Control Association (ATCA) is pleased to announce that former FAA Acting Administrator Linda Hall Daschle has been selected as the 2018 recipient of the prestigious Glen A. Gilbert Memorial Award, one of the most prominent awards in aviation and ATCA’s highest honor.

    A pioneer for women in air traffic management, Daschle was the first female to hold the post of Acting Administrator for the FAA. She began her aviation career in Kansas nearly 45 years ago as a licensed weather observer for the agency. In 1993, she was nominated by President Clinton and confirmed by the US Senate for the position of FAA Deputy Administrator. One of her first tasks involved an assessment of the agency’s key air traffic modernization program called the Advanced Automation System which was eventually overhauled, saving the agency an estimated $1.6 billion. She also oversaw the advancement of new regional airline safety regulations and conducted a review of the agency’s safety and surveillance program, which resulted in one of the single largest hires of new safety inspectors in FAA history. 

    Ms. Daschle has held numerous government and private-sector leadership positions, including with the American Association of Airport Executives, the Air Transport Association, the former Civil Aeronautics Board, and with the law firm of Baker Donelson. She is currently President of LHD & Associates, Inc, and serves on the board of Aireon, LLC.

    In accepting the Glen A. Gilbert Memorial Award, Ms. Daschle joins aviation greats, including Delta’s Richard Anderson, NATCA President Paul Rinaldi, the Hon. Jane Garvey, Boeing’s Neil Planzer, former Transportation Secretary Norman Mineta, and pilot A. Scott Crossfield. (View press release HERE.)
