Abstract: Disclosed is a method and system for avoiding collision between an aircraft A and an intruder aircraft. The method and system involve determining avoidance presets to avoid a collision between the aircraft A and the intruder aircraft, in which the avoidance presets comprise a vertical speed preset. The presets are determined from avoidance information received from an anticollision system, and the determined avoidance presets are transmitted to at least one guidance device that guides the aircraft A based on the avoidance presets.

Abstract: The invention relates to a method for producing an audible warning when an aircraft autopilot is deactivated. The method includes a) transmitting a first sound in the aircraft cockpit during a time ranging from a first predetermined value and a second predetermined value and b) transmitting a second sound in the aircraft cockpit. The invention also relates to an audible warning device having a monitoring unit for monitoring the deactivation of the aircraft autopilot and an activation unit for emitting an audible warning in the cockpit, where the activation unit is constructed such that it activates the first sound emission whose length ranges from the first predetermined value and a second predetermined value and a second sound when the monitoring unit detects the deactivation of the autopilot.

Abstract: The invention relates to a method for producing an audible warning when an aircraft autopilot (2) is deactivated consisting: a) in transmitting a first sound in the aircraft cockpit during a time ranging from a first predetermined value (d1) and a second predetermined value (d2) and b) in transmitting a second sound in the aircraft cockpit. Said invention also relates to an audible warning device (1) comprising first means (10) for monitoring the deactivation of the aircraft autopilot (2) and means (12) for emitting an audible warning in the cockpit, wherein said second means is constructed in such a way that it activates the first sound emission whose length ranges from the first predetermined value (d1) and a second predetermined value (d2) and a second sound when the first means detects the deactivation of the autopilot.

Abstract: The invention relates to an avoidance method and system for an aircraft, said avoidance system (1) comprising an anti-collision system (3), calculation means (4) for automatic determination of avoidance instructions, on an alarm, from avoidance information received from the anti-collision system (3) and an avoidance aid system (6, 21), connected to the calculation means (4) which aid the piloting of the aircraft (A), by means of the instructions received from said calculation means (4).
