Automatic Dependent Surveillance-Broadcast/Cockpit Display of Traffic Information: Pilot Use of Electronic VS Paper Map Displays During Aircraft Navigation on the Airport Surface

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 an electronic surface-map display (north-up, track-up) or a paper surface map. An analysis of 15 hours of communication data was performed 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 more problems occurred and more messages were exchanged for structured taxi routes. A statistically significant interaction indicated most problems occurred for the north-up map during structured taxi routes and the number of problems encountered was comparable for the other maps when pilots navigated along unstructured taxi routes. Avionics developers may want to reconsider north-up surface moving map displays airport surface navigation tasks.
