Defense Intelligence Reference Document Cognitive Limits On Simultaneous Control Of Multiple Unmanned Spacecraft
Defense Intelligence Agency · 31 pages · text from the file's own layer
This Defense Intelligence Reference Document, dated 15 December 2010, is a Defense Intelligence Agency report from its Advanced Aerospace Weapons System Applications (AAWSA) Program. It looks at how many unmanned spacecraft one human pilot could control during future deep-space missions, drawing on research into air traffic control and piloting of multiple unmanned vehicles. It concludes that the limits are about 16 craft for simple tasks, 7 for moderately complex tasks and 4 for complex mixed fleets. It adds that physiological measures can signal when an operator is overloaded.

interfaces reduces the maximum number of aircraft controllable to seven. 51 A final
study looks at an abstract model of continuous re-planning in different time intervals.
This study observes that subjects reacted differently, but in three groups, to automated
suggestions for re-planning. The authors conclude that human-automation consensus
is the primary driver of system performance. 52 In other words, the human-task
interaction must be taken into account, as suggested above by Averty, Loft, and others
outlined above.
