This book provides aircraft flight testers with the information required to appreciate the capabilities and limitations of the instrumentation techniques, indicating some of the many alternatives possible in flight instrumentation. It considers the systems concept in planning flight test instrumentation and functional organization of the component parts of an instrumentation system, followed by a discussion of the components of a flight data acquisition and reduction system that are organized into functional categories. Within these categories, a comparison is made between the various data collection systems and data reducing systems. The similarities, advantages, and limitations of each type of system component and significance of the fundamental properties of each device are also noted in this volume. This compilation is written primarily for persons not well-trained in electronics with special emphasis toward promoting the systems point of view in considering the problems of measurement in flight.
