This document presents detailed computer algorithms for programming the Automatic Traffic Advisory and Resolution Service (ATARS), formerly known as IPC, within a multi-site Discrete Address Beacon System (DABS) network. This document is to be used by Federal Aviation Administration to specify and define the ATARS portion of the integrated DABS/ATARS system. The FAA has directed that the Conflict Indicator Register (CIR) be replaced by the Resolution Advisory Register (RAR) as the avionics mechanism for coordinating resolution advisories between ATARS sites and between ATARS and BCAS. Since it will be some time before the RAR can be fully incorporated into the ATARS algorithms, a number of modifications have been made to the ATARS logic which will permit testing of the rest of the ATARS design, while eliminating the special CIR message requirements, now obsolete, upon the DABS sensor. These modifications constitute Revision 1 to the original MITRE technical report on the ATARS multi-site algorithms. (Author)
