Patent ID: 8725401

Claim:
A method of avoiding collision between an aircraft A and an intruder aircraft, while avoiding abrupt variations in load factor, said method comprising the steps of: a) determining avoidance presets to avoid a collision between the aircraft A and the intruder aircraft, wherein said avoidance presets are determined from avoidance information received from an anticollision system configured for monitoring trajectory of the intruder aircraft in proximity to the aircraft A and producing aircraft collision avoidance information to implement in-flight avoidance between the intruder aircraft and the aircraft A, wherein the avoidance presets are expressed in terms of load factor; and b) transmitting deflection orders, by an automatic guidance unit, to guide the aircraft A to avoid collision with the intruder aircraft, with the deflection orders being based on the determined avoidance presets, wherein in step a), the avoidance presets are determined by a calculation unit configured for: i) determining first resets expressed in terms of vertical seed for avoiding collision between the aircraft A and the intruder aircraft, and ii) transforming the determined first presets into the avoidance presets, wherein the determined first presets: are determined from the avoidance information received by the calculation unit from the anticollision system, and are transformed into said avoidance presets by: calculating a difference between a first determined vertical speed preset and a measured vertical speed of the aircraft A, applying a filter to filter variations in the calculated difference over time, and multiplying the filtered calculated difference by a gain dependent on air speed of the aircraft A.
