In accordance with methods and systems consistent with the present invention, an improved processor performance instrumentation system is provided that allows a software tester to measure more performance indicators than there are hardware counters during a single execution of a tested program. The improved processor performance instrumentation system accomplishes this by "multiplexing" performance indicators while executing the tested program. In effect, methods and systems consistent with the present invention extend the abilities of the limited number of hardware counters to allow them to measure a number of performance indicators otherwise not allowed during one execution of the tested program.

Method according to claim 1, wherein, if more than one new value of heading angle Θ 1band Θ 1cto be followed by the first aircraft, without changing its horizontal speed modulus to bring the horizontal speed vector V relof the second aircraft relative to the first aircraft to one of the sides X 2b, X 2c of the angle at which the second aircraft perceives the circle of protection of the first aircraft, has been determined during the determining at least one new value of heading angle, the step for determining at least one avoidance path includes determining two avoidance paths, one avoidance path for each of the two new values of heading angle Θ 1band Θ 1c. 4. Method according to claim 1, wherein, when the determining at least one avoidance path leads to determining more than one avoidance path, the method further comprises selecting the avoidance path to be implemented, including making a choice, from among the avoidance paths determined, of the path that minimizes a lengthening of the initial route of the first aircraft. 5. Method according to claim 1, wherein the at least one avoidance path determined during the determining at least one avoidance path comprises a second homing part for homing into the initial route, starting, from a rotating point marking an end of a first evasive part of the at least one avoidance path, with a rectilinear segment following a new heading which, with respect to a heading of the initial route, has an angular divergence opposite to that of the rectilinear segment of the first evasive part of the at least one avoidance path. 6. Method according to claim 5, wherein the rotating point that makes a transition, within said avoidance part, between an end of the rectilinear segment of the first evasive part and the rectilinear segment staffing a second homing part of the initial route, is chosen, on the rectilinear segment of the first evasive part, so that the rotating point is sufficiently distant from a point where a separation distance between the first and second aircraft passes through a minimum distance equal to the minimum safety distance so that the separation distance between the first and second aircraft does not go below the minimum safety distance, by the first aircraft, on the rectilinear segment starting the second homing part of the at least one avoidance path. 7. Method according to claim 1, wherein a modulus of half-angle |αb|or |αc|
