Abstract : This report documents the analysis performed by the COMSIS Corporation and SRI International of the proposed design for the ARTS IIA air traffic system for terminal areas with low to medium traffic density. ARTS II will be upgraded to ARTS IIA with the replacement of the LSI-2/20 minicomputer by the LSI-2/40, which is faster and has more memory capacity, and the addition of minimum safe altitude warning (MSAW), conflict alert (CA), a tracker to support these, and a training target generator (TTG). The study addressed the use of semiconductor memory in an air traffic system and the requirement for a battery backup power supply. The algorithms for the enhancements were studied to determine whether the LSI-2/40 has sufficient speed to perform them under traffic and display loads expected in 1990. It is concluded that the replacement computer has the capacity to perform the enhancement functions under maximum target and display load for the expected air traffic environment. (Author)
