ABSTRACT
This chapter considers the main influences on the arrangement of the displays within the workstation and in relation to each other with particular regard to their effects on the conduct of air traffic control. A common problem in air traffic control is that the information needed for all the tasks at a workstation cannot all be presented without violating some recommended viewing angles, viewing distances, codings or contrasts for displayed information. A major constraint on air traffic control workstation design has always been the need to tip the angle of the flight strip board back so that all the strips do not tumble out whenever a strip is discarded from the bottom of the heap. The available information content of air traffic control displays must cover all the visual information required for every task at each workstation, in forms matched to controller needs. In air traffic control, their shapes must be visually discriminable and their names audibly discriminable.
