David H. KlydeB.S. in Aerospace Engineering, California State Polytechnic University, Pomona, 1987

M.S. in Aeronautical Engineering, California State Polytechnic University, Pomona, 1990

Mr. Klyde’s experience includes dynamic analysis and system identification, flight control system design and analysis, human operator modeling, and handling qualities research for transport, fighter, UAV/drone, flying wing, rotorcraft and V/STOL, and hypersonic aircraft. His piloted simulation experience includes rotorcraft added dynamics studies, control inceptor force feedback cueing, on-line loss of control detection using wavelet-based techniques, handling qualities demonstration maneuvers development, moderate amplitude maneuvering criteria development, aircraft ground handling evaluations, and a hypersonic flying qualities study.

Mr. Klyde’s flight test experience includes loss of control alleviation and handling qualities evaluations using the Calspan Learjet in-flight simulator, ground handling evaluation of the Navy T-45 jet trainer, a probe-and-drogue demonstration maneuver evaluation program conducted by the USAF Test Pilot School using the variable stability NT-33A, a post-stall maneuvering program with the NASA F/A-18 High Alpha Research Vehicle, and a high speed flying qualities research program with a NASA SR-71. Together with Mr. David Mitchell of Hoh Aeronautics, Inc., Mr. Klyde created a two day short course on the study of Pilot-Induced Oscillations that has been presented to the Air Force Flight Test Center, the Naval Air Systems Command, NASA Dryden Flight Research Center, Boeing Long Beach, Boeing Philadelphia, Bell, and Sikorsky.
