Abstract

To accomplish air traffic growth in a safe and efficient way, future air traffic management concepts require aircraft to accurately execute 4-dimensional (4D) trajectories. A trajectory planned prior to takeoff, might, however, require in-flight revision. To support the flight crew in their task of accurately replanning a flight plan up to a metering fix, in 4 dimensions, a dedicated planning interface has been designed, adopting a cognitive systems engineering approach. The interface allows direct manipulation of the ground track and the descent profile. Constraints on trajectory planning are mapped onto alternative waypoint locations, highlighting the possibilities for acceptable ground track geometry in the horizontal situation display. In the vertical situation display, these constraints are mapped onto candidate top- and bottom-of-descent locations. It is hypothesized that the designed interface enables pilots to efficiently plan suitable 4D trajectories, while allowing for adaptive behavior and supporting situation awareness, even under high workload conditions.
