Conflict Resolution Advisory CRA is an automated software aid for air traffic control specialists at air route traffic control centers ARTCCs. CRA calculates, validates, and displays to the en route controller a single resolution for predicted separation violations detected by the conflict alert CA function. This simulation study was conducted to determine controller response time to a CRA message. The response time is the total time required for controllers to notice that the advisory is present, to read and comprehend the text message, and to decide that the resolution is acceptable. Since only the prototype software CRAU was available for this test, the only other issue that was formally addressed was controller comments on the CRA message format. The implication of the results of this study for the calculation of the delay that is to be expected between CRA onset and pilot response is also discussed.
