Is the effect of aviation automation on pilots comparable to the effect vehicle automation on drivers? Decades of research has focused on the human factors implications of automating different aspects of aviation. However, much of the human factors research into the field of vehicle automation seems to not be drawing on this experience either in their literature or in the design of the methodologies and I wondered why. Is it that researchers are unfamiliar with aviation automation literature or is there something fundamentally different between the two domains that make comparisons difficult?
