In older cockpits information
about several kinds of potential hazards has been presented on multiple
displays. Air traffic, weather, and terrain hazards are all displayed in
3-space and time coordinates, but the pilots must integrate monitor the
information on separate displays and integrate it in their minds. Combining
the hazard information with navigation information on a single display should
allow greater accuracy and reduced cognitive workload. A number of integrated
displays are under development in laboratories and several are in commercial
production.
Color usage in these integrated displays is more complicated than in separate
displays. Aircraft symbols move relative to each other and the background
terrain colors. Areas of weather move relative to the terrain background
and the aircraft. The displays therefore involve many more combinations
of symbol and background colors than in simpler displays.
Our laboratory is studying various color designs for these integrated displays.
