Cockpit automation is here and will continue to increase in future aircraft. Concern has been raised about the pilot's roles and responsibilities vis a vis a very sophisticated computer - referred to by the authors as an electronic crewmember or EC. This paper argues that the EC and the pilot can work together as a team, rather than as adversaries. A scheme for characterizing different levels of cockpit automation, and an attendant role for the EC, is reviewed. This is followed by a discussion of those operational situations in which the pilot is most likely to trust the decisions made by the EC as opposed to those situations where the pilot is likely to turn the EC off. The notion of “prime directives” or basic operating rules for the EC is presented as well as a multiple clock concept, a philosophical basis for an adaptive cockpit. The paper concludes with three brief mission scenarios describing various levels of EC/pilot interaction.
