Evaluation of Flight Deck Procedures Used in the Designation of Traffic for Tailored Collision Avoidance Logic

The Airborne Collision Avoidance System (ACAS Xₒ) allows a pilot to select traffic for tailored collision avoidance advisories during simultaneous approaches to parallel runways. In the study reviewed in this paper, pilots evaluated ACAS Xₒ procedures during a series of simulated approaches and departures. Half of the pilots were given the traffic to select by Air Traffic Control (ATC), while the remaining pilots had to determine the appropriate traffic to select on their own. Pilots who received the traffic from ATC selected targets more quickly and earlier in the approach. Pilots felt the process was easy and the workload was operationally acceptable. Analysis showed that earlier selection increased the utility of ACAS Xₒ and was preferred by pilots as it allowed the crew to complete the procedure in a lower workload phase of flight.
