This Monograph is a fascinating account of the journey made by Aeronautical Development Establishment (ADE), Bengaluru from its first analog automatic flight control system for an air launched drone (1974) to sophisticated digital Flight Control System (FCS) for the fly-bywire supersonic fighter (2001) and to the autonomous low-level cruise platform (2013). A great deal of the technology described is a compilation of the work done by two generations of scientists and engineers at ADE and other co-operating institutions. Monograph would help the future entrants to flight control research and development programmes to adapt themselves to their roles more easily.
