Abstract

Air-traffic control workload data was collected from 20 enroute radar sectors in northern Australia. Multi-level analyses were used to model the effects of traffic variables and airspace variables. The effect of aircraft count varied significantly between sectors. Aircraft count had a stronger effect on workload in sectors that typically have a larger proportion of aircraft on descent, and aircraft that are more closely spaced. Implications for the development of predictive workload metrics are discussed.
