This paper reports on the flight evaluation and demonstration of a tool designed to support an approach spacing concept at the Chicago O'Hare International Airport. The purpose of the flight activity was to evaluate the Advanced Terminal Area Approach Spacing (ATAAS) tool in an operational environment as well as demonstrate different applications of the tool. Delivery precision at the runway threshold was the primary evaluation metric, and it was found to be good with an overall mean inter-arrival error of 0.8 seconds. From the pilot’s perspective, it was found that the task of flying the ATAAS-generated speed guidance could be easily integrated into normal crew duties. Finally, the paper notes that even though it was not evaluated in the flight activity, it was found that the ATAAS tool could reduce the required number of voice communications.
