Aviation Systems Division Researchers Receive Awards for Patents, Inventions and Contributions
January 24, 2014

On January 22, 2014, several Aviation Systems Division researchers were the recipients of awards selected and conferred by NASA Ames Research Center's Inventions and Contributions Board and sponsored by the Ames Technology Partnerships Division. The Patent Application awards were given to the following Aviation Systems Division members for the completion of a non-provisional patent application filed with the US Patent and Trademark Office:

Kapil Sheth, Dave McNally, and Heinz Erzberger,
“Method and System for Dynamic Automated Corrections to Weather Avoidance Routes for Aircraft in En Route Airspace”

Software Release Awards were given to the following employees for completion of the Software Release Authority documentation:
Larry Meyn, Heinz Erzberger, Daniel Mulfinger, Leonard Bagasol, Jane Thipphavong, and Danny Chiu,
“Stochastic Terminal Area Scheduling Simulation (STASS)”

Harry Swenson, Xiao Liang Chen, and John Robinson,
“Terminal Sequencing and Scheduling Software for Air Traffic Control”

Tech Briefs Awards were given to the Future Air traffic management (ATM) Concepts Evaluation Tool (FACET) team, upon documentation of approval of an article for publication in the NASA Tech Briefs magazine. The team members were: Karl Bilimoria, Gano Chatterji, Shon Grabbe, Kapil Sheth, and Banavar Sridhar.

The Traffic and Atmospheric Information for General Aviation (TAIGA) project has successfully demonstrated sending a message from an Internet-connected computer terminal through a satellite channel to a mobile receiver. The goal of TAIGA is to provide improved situational awareness to general aviation and air taxi pilots in Alaska through better access to data and better interaction with that data on a modern, off-the-shelf mobile device. Work is ongoing to connect the iOS-based TAIGA app to the mobile receiver so that the data sent via this communication channel will be accessible to general aviation pilots using the system. Using custom compression algorithms, various data, specifically, PIREPs (pilot reports), METARs (aviation weather reports), and various weather polygons can be sent to pilots in airspace regions where other communication methods are infeasible.

In addition to Dr. Heinz Erzberger's receipt of the AIAA 2014 Intelligent Systems Award (see highlight October 21, 2013), Aviation Systems Division members participated in the AIAA SciTech 2014 Conference held January 15-17 in National Harbor, Maryland, presenting papers and serving as technical committee chairs.

Dr. Banavar Sridhar presented the paper “Aircraft Trajectory Design Based on Reducing the Combined Effects of Carbon-Dioxide, Oxides of Nitrogen and Contrails” in the Modeling and Simulation Technologies Conference. Dr. Neil Chen presented the paper, “Evaluating Tradeoff between Environmental Impact and Operational Costs for En Route Air Traffic” in the Guidance, Navigation and Control Conference.

Dr. Sridhar also visited NASA Headquarters on January 15 to provide an overview of the research on the impact of aviation emissions and contrail reducing strategies to Dr. John Cavolowsky and other Airspace Systems Program staff. On January 16, Dr. Sridhar and Dr. Chen were invited to present aviation emission reducing strategies to members of the Federal Aviation Administration's (FAA's) Energy and Environment Division (Dr. James Hileman, Dr. Mohan Gupta and Dr. Rangasayi Halthore). The two groups discussed coordinating contrail reduction strategies with FAA-funded contrail models. (POC: Banavar Sridhar)
