EUROCONTROL’s Feasibility of ACAS Resolution Advisory Downlink Study (FARADS) is investigating the feasibility of showing simplified ACAS resolution advisories (collision avoidance advice given to pilots) on controller screens. As part of this study, an experiment was conducted in which resolution advisories (RAs) were displayed to controllers. This experiment took place from 17 November to 28 November 2003, and a total of 30 controllers from ten European Area Control Centres participated. The majority of the participants see clear operational benefits in the provision of RA information to the controller. Because RA downlink is faster and more reliable than a pilot report of an RA, it can support the controller’s anticipation of aircraft manoeuvres. This can be considered an improvement in situational awareness. Furthermore, most participants expect RA downlink to decrease the likelihood of contradictory ATC clearances to the conflict aircraft.
