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.

Figure 3. Air Traffic Control: a) overview of a large TRACON facility. Potomac is pictured. b) A
single ATC TRACON station. Beside the radar display is a stack of memory aid blocks when the
controller writes essential aircraft information - as long as there is a physical block to the right,
there should be a corresponding "blip" on the screen. c) TRACON display from Minneapolis-St. Paul.
On this display are aircraft under control (undesignated), as well as craft from 3 other controllers,
East (E), North (N), and Ground (G). Below each aircraft name is controller designation, altitude in
hundreds of feet, and airspeed 1n tens of knots.
