  • (a) calculating probabilities, for the own aircraft, that the own aircraft is situated in predetermined space elements at a plurality of selected times (occupancy probabilities); and

    (b) from the occupancy probabilities of the own aircraft and the occupancy probabilities of at least one other object in the vicinity of the own aircraft, calculating the probabilities of the simultaneous occupancy by the own aircraft and the other object (collision probabilities) for the predetermined space elements at the selected times.
