The use of satellite technology for oceanic air traffic control
Article Abstract:
Use of satellite communications to control aircraft flying over oceans is discussed. The International Civil Aviation Organization (ICAO) provides air traffic services over large areas of the Atlantic and Pacific oceans and differs considerably from the system used in the contiguous US. Aircraft in domestic airspace are illuminated by radar once every 12 seconds, and radio communication is more frequent. Oceanic airspace is monitored via high-frequency radio channels, which are easily affected by ionospheric propagation conditions and electrical storms. The cleared flight plan (clearance) and the pilot-reported position (progress report) are used to track oceanic aircraft. The ICAO Future Air Navigation Systems Committee was formed in 1983 to study, identify and assess new air navigation techniques, including space-based radar, cooperative independent surveillance and automatic dependent surveillance. Their work is described.

National Airspace System demand and capacity modeling
Article Abstract:
The National Airspace System Performance Analysis Capability (NASPAC) was developed by the US Federal Aviation Administration (FAA) and MITRE Corp to use computer models and operations research techniques to find capacity limitations at US airports and in US airspace and to study alternative solutions. NASPAC examines the entire US airport and airspace network for analysis of the effect of problems or limitations in one area on other areas and the nation as a whole. NASPAC analysts have backgrounds in air traffic control, operations research, simulation modeling and transportation engineering. The analytical queueing model used is intended to provide estimations of the effect of changes affecting only one area directly, such as a runway closed for repair, and the discrete-event simulation intended for detailed systems-level problem analysis.

The US air traffic control system architecture
Article Abstract:
The US National Airspace System (NAS) is comprised of the physical airspace above the US and the equipment, facilities and people fulfilling the policies and procedures that manage travel in the air. Application of digital processing has changed almost every aspect of air travel in recent years, making safe, all-weather operations more routine, but this also puts increased operational demands on air traffic control facilities. The historical evolution of the US air traffic system is described, and the work of the civil and military sectors in the development of the architecture is discussed. Nine major elements, each characterizing the significant technologies applied to realize the NAS Plan for Facilities and Equipment, are described separately. Recent and future automation plans are discussed.
