Abstract
The Federal Aviation Administration is making a concerted effort to reduce runway incursions. A 5-day operational evaluation conducted in October 2000 assessed pilot use of varying types of CDTI devices. Structured and unstructured taxi routes examined how well pilots navigated their aircraft using electronic surface-map displays (north-up, track-up) or a paper surface map. An analysis was performed of 15 hours of communication data to determine how the use of these displays might aid situation awareness and influence operational communications. A Type-of-Route x Type-of-Map ANOVA revealed that more problems occurred, and more messages were exchanged for structured taxi routes. Most problems occurred for the north-up group during structured taxi routes, and the number of problems encountered was comparable for the other map groups when pilots navigated unstructured taxi routes. The format in which a map is presented appears to affect some aspects of pilot performance during airport surface navigation.
