> **MOVING MAP DISPLAY**

In support of the Low-Visibility and Surface Operations element of the
Terminal Area Productivity (TAP) Program, the Flight Deck Branch in the
Flight Management & Human Factors Division conducted a study aimed at
evaluating pilots\' ability to navigate around the terminal using an
integrated moving map display. Participating pilots flew scenarios
start­ing 12 miles out into Chicago\'s O\'Hare Airport under varying
visibility conditions. They were then instructed to taxi to their
assigned gates by one of three methods. The first method included the
standard operations being used today, using Jeppesen charts and
instructions from ground control. This method involved no use of the
moving map display. The second method also used today\'s standard
operations, but also provided the pilots with the moving map display,
allowing for enhanced situational awareness. The third method provided
the enhanced version of the moving map display showing routing
clearances overlaid on the map, as well as the position of other
aircraft via data-link. Other goals of this experiment included
assessing changes in heads-down time as a result of introducing advanced
navigation display systems during re­duced visibility operations, as well
as evaluating pilot workload, and obtaining pilot feedback on the use of
advanced navigation display systems during ground taxi operations.

> runways, terminal build­ings, taxiways and taxi-way signs. These in
> turn had to be aligned with the researchers moving map display
> computers and the CVSRF\'s air traffic control (ATC) simula­tion, to
> ensure that each of the systems were reading the same positional
> information. This was very critical with the enhanced version of the
> map display when depicting the position of other aircraft in the

> computers as well as the type of data being transmitted across the two
> systems had to be implemented in sup­port of this

> Overall, 12 different 747-400 crews participated in this study
> spanning a period of 11 weeks. Each of the runs took two days to
> complete, resulting in 288 runs. For each of these runs, digital data,
> videotapes and pilot questionnaires were collected. Some preliminary
> results indicate that participating pilots were very excited about the
> potential usage of the moving map display and its possible benefits
> towards improving safety while taxi­ing inthe terminal area. In
> addition, subject pilots also felt there was a definite reduction in
> pilot workload as a result of utilizing the moving map display.
