Abstract:

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. This 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. The mean time required to decide that a resolution was acceptable was 18 seconds S. D. 8.6 . This result is compared to the response time of 13 seconds S.D. 6.2 observed with the CRA prototype and the implications of these results for estimating the delay between CRA onset and pilot response are discussed. Controllers opinions regarding the CRA function are also reported.... Controller-Response time, Conflict resolution advisory.
