Abstract:
1. A method for preventing at least some alarms to be emitted by an anti-collision system on board ( 2 ) an airplane (AC) during an altitude capture maneuver comprising a phase for capturing an altitude 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 alarms of the first type and alarms of the second type, when such a theoretical collision time is lower respectively than a first threshold and a second threshold, said method being able to implement a step of adaptation of said altitude capture maneuver by a control of the vertical speed of said airplane (AC) so as to prevent at least some of said alarms from being emitted, characterized in that: A/ during said altitude capture maneuver, the emission of an alarm of the first type is first detected; B/ said first alarm threshold (S C/ an activation height threshold (ha) is established from said first determined alarm threshold (S
