of aerospace graphics currently face particularly difficult challenges.
Introduction of new technologies into the cockpit and air traffic control
centers is highly regulated, as one might expect considering the public
safety implications. The cost of implementation is also high in the widely
diverse fleet of long-lasting aircraft. Consequently, change has come
slowly to aerospace graphics. As a result there is a substantial gap between
data systems and displays in aerospace and those in other commercial settings.
As the capabilities of the hardware and software in aircraft and air traffic
control centers increase there is pressure from the operational community
for very large changes in the types
and amounts of information displayed in aerospace applications.
of Cockpit Graphics
cockpit displays. Cockpit displays have only recently included
color capabilities. This is a NASA research display, with several
advances beyond the usual navigation display. Color-coded traffic
data are displayed, and tools to assist planning for traffic
are provided. Luminance contrasts have been designed to reduce perceptual
clutter, an important consideration in displays that are only
broad "situation awareness" responsibility.
cockpit displays. Hazard data of several types are simultaneously
displayed in this prototype display. Addition of area variables (terrain,
weather) requires careful management of colors to meet legibility,
attention management, and color-coding demands.

Traffic Management displays. The FAA is in the process of
replacing aging displays in air traffic facilities with new
systems that have
vastly improved graphic capabilities. The older graphics were limited
to achromatic, bright symbols on dark backgrounds. Users could
the luminances of large classes of data symbols to try to manage
clutter but the tools were limited. The display at left is a NASA research display
with appearance that
approximates older ATC displays.
Air Traffic Management Displays.
As in the cockpit hazard display above, hazard
data of several types are simultaneously displayed in this prototype
ATC display. Addition of area variables (terrain, weather) and new
software decision-support tools require substantial changes from traditional ATC graphics
to meet legibility, attention management, and color-coding demands.

Chart Example: This is a sample from the printed NOAA San
Francisco sectional chart. Aviation charts have very high data
is just one of several graphic variables used to achieve the visual
hierarchy of the information. As part of a general trend toward less
paper in the cockpit, designs are being developed to display this
information in electronic form. The sophisticated
designs of these paper charts and the high data density provide big challenges
for the designers of electronic versions.
