Abstract
To provide maximum comfort for passengers, it is claimed that cabin pressures must be maintained within very-narrow limits. The various steps by which a system was developed to accomplish such control is discussed and illustrated by photographs and diagrams. The author believes that the final result of the research and development program is a system which will not only provide the necessary control, but will do so with a degree of reliability unknown in earlier systems, with a minimum of maintenance and extremely simple in operation. Two production systems are described in detail with a final explanation of how a transistorized pre-amplifier and magnetic amplifier is used.
