Air traffic controllers in the Federal Aviation Administration can submit voluntary safety reports when significant safety concerns and potential safety events are encountered during their everyday operations. We tested two questions: Can safety reports be classified according to whether the risk was known or unknown to the controller or the system; and would classifying reports in this manner yield useful safety information? A sample of 36 reports was assessed using this known-unknown method. 55% of the reports were classified as risks known to the controller but unknown to the system. 17% of the reports were scored as known to both the controller and the system. 14% were classified as unknown to the controller but known to the system, and 14% as unknown to both the controller and the system. Trends, limitations, and next steps are discussed.
