Aircraft Instrumentation and Systems covers broadly the topics for the undergraduate course on Aircraft Instrumentation. It includes: an introduction to aircraft instruments and systems; air data systems and air data computers; navigation systems; gyroscopic flight instruments; engine instruments; electronics flight instrument systems; safety and warning systems. Every effort has been made to update the contents of the book with information on the most recent technology used in modern transport aircraft manufactured by Boeing and Airbus. The text is profusely illustrated with block diagrams, schematic diagrams, and a number of tables, as well as a glossary. Review questions have been included at the end of the each chapter to help with practice and self-study. The book is intended for both teachers and students, especially students of B.E., M.E. and students in Instrumentation Technology and Aircraft Engineering. It also introduces the subject to practising engineers and readers interested in aircraft instrumentation, as well as to the flight crew.
