PRELIMINARY COMPUTER SIZING ESTIMATES FOR AUTOMATED EN ROUTE ATC (AERA)

The Federal Aviation Administration is presently analyzing requirements for the computer system that will replace the IBM Model 9020 computers, that currently support the en route NAS system, as well as the computers that support the terminal ARTS facilities. As an early input to the requirements analysis effort, the FAA's Office of System Engineering Management requested a preliminary analysis of computer loads imposed by near-term enhancements to the existing NAS and certain long-term enhancements. This report presents an analysis that estimates the computer sizing requirements imposed by the Automated En Route Air Traffic Control (AERA) system, a possible long-term enhancement to NAS. In order to establish preliminary AERA processor and memory requirements, two models are presented. A simulation model of the higher level AERA functions, such as initial processing and progress monitoring, is applied to the Washington Center to show typical AERA imposed processor loading. A previously developed linear model of required memory is also applied to show typical memory requirements resulting from AERA. The models presented reflect a version of AERA existing during December, 1978. That version of AERA did not include the recently developed concepts of strategic and tactical planning/control. Additionally, since AERA will continue to evolve during the development stage, requirements enumerated must be considered preliminary in nature and significant changes on the estimates may be expected. Throughout this analysis, it is assumed that there is no integration of the existing NAS functions and the AERA functions.
