The investigation examined the effects of differential target velocity, horizontal or vertical plane conditions and air traffic controller experience on the intersection time estimation accuracy of two converging targets. Performance accuracy on this task was not significantly affected by horizontal or vertical conditions nor by air traffic controller experience. However, accuracy in magnitude and direction was found to significantly vary as a function of cursor speed with slower speeds producing the poorer performance. A differential effect for various speed combinations was also noted. Estimation accuracy on the slowest cursor speed when paired with the two faster speeds was decreased while accuracy on the intermediate speed was degraded when combined with either slower or faster speeds. Estimations on the fastest speed were not affected by differential pairings.
