Abstract :
Harry Diamond (National Bureau of Standards, Washington, D. C): It may be of interest to compare the Civil Aeronautics Authority system at Indianapolis with the system set up by the National Bureau of Standards at Newark about seven years ago.∗ Many instrument landings were made on the Newark installation and the setup was considered by many pilots as suitable for airline experimental use. The achievements represented by the Indianapolis setup lie primarily in the provision of control of the individual elements of the system.
