For pilots to accept active decision aids during complex flight scenarios,
it is essential that the automation work in synergy with the aircrew. To ac
complish this, the automation must go well beyond menu and macro selections
, where the pilot explicitly tells the automation what to do and when to do
it. It must also transcend "mother may I" approaches, where the automation
asks for permission to proceed. To breach these traditional barriers, the
automation needs a sense of how the pilot will react in a given situation a
nd, based on that reaction, how much of the workload could be allocated to
the automation at any given time. To advance the applied aspects of the res
earch in this area, the authors transitioned results from three major resea
rch efforts. We implemented a dynamic model of pilot trust and workload all
ocation that correlates with the human data collected during those efforts.
This "full degrees of freedom" engineering model is an early attempt to bu
ild a continuous adaptive process that divides cockpit workload between hum
an and machine, and that minimizes human cognitive overload. This paper pro
vides implementation detail, and relates those details to the original rese
arch and human factors literature. An example of the model's use based on a
n involved flight scenario is presented. (C) 1999 Elsevier Science Ltd. All
