Abstract: An airborne air-to-ground data link communication interface was evaluated in a multi-sector-planning scenario using an Airbus A 340 full flight simulator. In a close-to-reality experimental setting, eight professional crews performed a flight mission in a mixed voice/data link environment. Experimental factors were the medium (voice vs. data link), workload (low vs. high) and the role in the cockpit (pilot flying vs. pilot non-flying). Data link communication and the usability of the newly developed communication interface were rated positively by the pilots, but there is a clear preference for using a data link only in the phase of cruise. Cognitive demands were determined for selected sections of en-route flight. Demands are affected mainly by increased communication needs. In the pilots’ view, although a data link has no effect on safety or the possibilities of intervention, it causes more problems. The subjective workload, as measured with the NASA Task Load Index, increased moderately under data link conditions. A data link has no general effect on pilots’ situation awareness although flight plan negotiations with a data link cause a distraction of attention from monitoring tasks. The use of a data link has an impact on air-to-ground as well as intra-crew communication. Under data link conditions the pilot non-flying plays a more active role in the cockpit. Before introducing data link communication, several aspects of crew resource management have to be reconsidered.
