Contains recommendations describing the need for a Federal Aviation Admin. (FAA)-wide systems architecture in modernizing Air Traffic Control (ATC), and assesses FAA's efforts to develop and utilize one. Reviews FAA's ATC modernization to determine (1) whether FAA has a target architecture(s), and associated subarchitectures, to guide the development and evolution of its ATC systems; and (2) what, if any, architectural incompatibilities exist among ATC systems, and the effect of these incompatibilities. Charts, tables and photos.

Page 5 - National Airspace System (NAS). The common network of US airspace; air navigation facilities, equipment and services, airports or landing areas; aeronautical charts, information and services; rules, regulations and procedures, technical information, and manpower and material. Included are system components shared jointly with the military.
Page 16 - Most of the en route centers' controlled airspace extends above 18,000 feet for commercial aircraft. En route centers also handle lower altitudes when dealing directly with a tower, or when agreed upon with a TRACON. Two en route centers — Oakland and New York — also control aircraft over the ocean.
Page 62 - Terminal radar approach control (TRACON) facilities sequence and separate aircraft as they approach and leave airports, beginning about 5 nautical miles and ending about 50 nautical miles from the airport and generally up to 10,000 feet above the ground. Air route traffic control centers called en route centers, control planes in transit and during approaches to some airports.
Page 14 - It also anticipated that meeting the demand safely and efficiently would require improved and expanded services, additional facilities and equipment, improved work force productivity, and the orderly replacement of aging equipment. Accordingly, in December 1981, FAA initiated its plan to modernize, automate, and consolidate the existing ATC system by the year 2000.
Page 20 - ... operations.6 Each type of facility highlighted in the previous section contains numerous interrelated systems. For example, the en route centers alone rely on over 50 systems to perform mission-critical information processing and display, navigation, surveillance, communications, and weather functions. These include the systems that display aircraft situation data for air traffic controllers, the system that collects and displays data from various weather sources, radars for aircraft surveillance,...
