TheAdvanced Terminal Area Approach Spacing (ATAAS) tool uses AutomaticDependent Surveillance-Broadcast (ADS-B) aircraft state data to computea speed command for the ATAAS-equipped aircraft to obtain arequiredtime interval behind another aircraft. The tool and candidate operationalprocedures were tested in a high-fidelity, full mission simulator with activeairline subject pilotsflying an arrival scenario using three different modesfor speed control. Eyetracker data showed only slight changes ininstrument scan patterns, and no significant change in the amount oftimespent looking out the window with ATAAS, versus standard InstrumentLanding System (ILS) procedures
