uman error has been identified as a dom-inant risk in aviation and other safety-oriented industries. For air traffic control (atC) and air traffic management (ATM), it is important to understand factors that lead to human errors within current systems, particularly those con-tributing to violations of separation standards, the report says.
Before human error can be prevented, an un-derstanding is needed of when and where it occurs in existing systems, as well as of the system variables that contribute to it. To reach such an understanding, meaningful data from individuals and ATM systems must be captured and analyzed.
This report describes the evaluation of one technique, JANUS, to determine its suitability for identifying incident causal factors in relation to current investigation methods. [JANUS is not an acronym but refers to the ancient Roman god of doors and gates, with a double-faced head looking simultaneously forward and back. The name was adopted to symbolize looking at types of past incidents and at how they can be avoided in the future.] “Strengths of the JANUS technique include use of a structured-interview process so that psychological errors contribut-ing to the air traffic controller’s behavior can be identified and lessons learned from the incident,” says the report.
