Abstract:
1. A method for preventing at least some alarms from being emitted by an anti-collision system ( 2 ) on board an airplane (AC) during an altitude change maneuver comprising an approach phase followed by a phase for capturing a set level (Zc), said anti-collision system ( 2 ) being able to detect at least one intrusive aircraft (AI) being located in the air environment of said airplane (AC), to calculate a theoretical collision time between said airplane (AC) and said intrusive aircraft (AI) and to emit first type alarms (TA) and second type alarms, when such a theoretical collision time is lower respectively than a first predetermined triggering threshold and a second predetermined triggering threshold, characterized in that, when said airplane (AC) is flying to said set level (Zc) with a vertical speed (Vz), the absolute value of which is at least equal to a first predetermined vertical speed threshold (Vz
