abstract="We analyzed the extent to which a high false alert rate of the conflict alerting (CA) system in five ATC facilities was the cause of a &quot;cry-wolf&quot; effect, whereby true alerts of a pending loss of separation were associated with either controller failure to respond, or a delayed response. Radar track data surrounding 497 CA's were examined and from these we extracted information as to whether the alert was true or false, whether a trajectory change was (response) or was not (non-response) evident, whether a loss of separation occurred, and the controller response time to the CA. Results revealed an overall 47% false alert rate, but that increases in this rate across facilities was not associated with more non-responses or delayed responses to true alerts, or loss-of-separation. Cry-wolf appeared to be absent. Instead, desirable anticipatory behavior indicated that controllers often responded prior to the conflict alerts.<p /><p>Language: en</p>",
