Abstract : A real time simulation was conducted to evaluate simultaneous ILS approaches to two runways spaced 3000 ft apart with one localizer offset by 2.5 degrees. Air traffic controllers monitored traffic using a simulated Precision Runway Monitor (PRM) system which consisted of Final Monitor Aid (FMA) displays and a simulated radar update rate of 1.0 second. Aircraft blunders were introduced to test the air traffic control system ability to maintain adequate separation between aircraft on final approaches during critical situations using the proposed runway configuration. Four criteria were developed by the Multiple Parallel Approach Program (MPAP) Technical Work Group to evaluate the study: (1) the number of Test Criterion Violations (TCVs) relative to the total number of at-risk, non-responding blunders, and relative to a predetermined target level of safety of no more than one fatal accident per 25,000,000 approaches; (2) the frequency of No Transgression Zone (NTZ) entries and nuisance breakouts (NBOs); (3) an evaluation of controller communications workload; and (4) an operational assessment from MPAP TWG members and participating controller and pilot technical observers. The results of the simulation passed all of the test criteria The MPAP TWG recommended the 3000-ft dual offset procedure for approval in the operational environment, given similar controller and pilot training, when the PRM system is used.
