Conceptual design of free flight with airborne separation assurance


== Abstract ==

The study described in this paper originally only aimed at studying the human factors problems of airborne separation hi a Free Flight environment. However to define the Free Flight environment with sufficient detail, a concept was designed at NLR. This conceptual design includes rules-of-the-sky, a conflict resolution algorithm, conflict detection, cockpit display recommendations, system description as well as operational implications. The feasibility of the design has been evaluated in three sub-studies: (i) off-line traffic simulations with very high traffic densities and a total of up to 300 aircraft, (ii) a safety analysis comparing the resolution method with current day ATC and (iii) a man-in-the-loop simulator experiment hi traffic densities up to three times the average WestEuropean traffic density with eight air line crews. None of these studies could refute the feasibility of the Free Flight conceptual design.
