The goal of the present study was to examine the impact of different data-communications (Data Comm) methods and use of multi-dimensional displays (2-D or 3-D) on pilot workload when Trajectory Based Operations (TBO) is employed. Eight pilots flew simulated enroute flights using an integrated (FANS-I A) or non-integrated (ACARS) Data Comm method. Pilots were also asked to rate the workload and acceptability of a route modification with the different Data Comm methods. No performance differences were observed as a function of data-communications methods or use of multi-dimensional displays. Online assessments during the flight simulation also showed no difference in pilot ratings of workload and route acceptability. However, in post-trial questionnaires, pilots reported an overall preference for FANS as a Data Comm method compared to ACARS. The display type did not change pilots' positive ratings for the FANS method, but 3-D displays increase the operator's ability to understand the proposed flight plan changes when they used ACARS.
