Dave was a research aerospace engineer in the Aviation Systems Division at NASA Ames Research Center from 1984 through 2016. He has 21 years of experience in laboratory development, human-in-the-loop simulation, and operational testing of flight trajectory-based automation for en route air traffic controllers and airline dispatchers. Dave led four operational trials at FAA Air Route Traffic Control Centers including that of NASA’s Direct-To tool at Fort Worth Center, the first demonstration of continuous automatic search for operationally acceptable, conflict-free routes that can save significant wind-corrected flight time. Dave led the development of NASA’s Dynamic Weather Routes (DWR) tool including the highly successful 2+ year trial of DWR at the American Airlines dispatch operations Center. The DWR trial resulted in significant flight time savings for over 500 revenue-generating American Airlines flights. Dave’s experience includes software requirements specification, integration of trajectory automation with Controller/Pilot Data Link Communication (CPDLC), and advocacy at all levels from end users to senior management including NASA & FAA Administrators and airline VPs. Prior to his work in air traffic automation Dave was the NASA lead on a joint DoD/NASA/FAA/Industry flight research project to demonstrate the use of Differential GPS for Category III precision landing guidance. Dave is the author or co-author of 38 technical publications, and he holds US Patents on DWR and Direct-To technologies. He is currently Chief Technology Officer at Route Dynamics Corp, a company exclusively focused on meeting unrelenting demand for efficiency in the airline market.
