After a successful flight test on Calspan's variable-stability Learjet aircraft last year, an L1 adaptive flight control system is being modified for the U.S. Air Force's VISTA F-16 aircraft by Professor Naira Hovakimyan and her graduate students, Kasey Ackerman and Javier Puig-Navarro. Hovakimyan, a W. Grafton and Lillian B. Wilkins Professor in MechSE, has been developing the L1 adaptive control theory since 2005.
