Mr. Sherer

The symposium this evening will be devoted to the operational phases of the Common System. The designation “Common System” is significant. It derives from the fact that it is designed to serve the common needs of all users of the airspace, both military and civil, and that its various elements are integrated to work together un a system basis. It must be remembered that the Common System is not intended to satisfy requirements which are peculiar to a particular branch of aviation such as, for example, the tactical requirements of the military services or the administrative communication requirements of the scheduled air carriers.
