While other modes of transportation have had a fairly predictable base for projecting future requirements, aviation has historically suffered from underestimating its rate of growth. Couple this with the high speed and short response time of this dynamic business, and we have today's airport and airway dilemma. Analysis indicates that the greatest benefits in system capacity will come from airport improvements and construction. A parallel and companion requirement is airways modernization. Automation and procedural changes are forecast not only to improve operations and capacity at reasonable cost, but can be implemented to offset and hold the line until the expensive and long term airport improvements can be completed.This paper discusses the basic computational-beacon tracking level under contract to be implemented at 64 terminal facilities beginning in 1970, and the important add-on packages under development to increase system reliability and capacity.
