Method making it possible to identify the proximity of a wake turbulence and to generate a report relative to that proximity
First Claim
1. A method implemented by an aircraft comprising a processor, a receiver, and a transmitter, the method to identify a proximity of a wake turbulence generated by at least one generating aircraft and to generate a report relative to the proximity, the method comprising:
- a data acquisition step during which the processor retrieves and records data, received by the receiver, relative to each generating aircraft present around the aircraft;
a position estimation step during which the processor estimates a position of wake turbulences generated by each generating aircraft;
a proximity step during which the processor determines if the aircraft is close to at least one of the wake turbulences whose positions have been estimated;
a first computation and comparison step which comprises a first computation sub-step, during which the processor computes external moments to which the aircraft is subjected, and a first comparison sub-step, during which the processor compares the moments with threshold values;
a generation step during which the processor generates a report, in response to the first comparison sub-step being positive, containing data relative to each wake turbulence which has been considered as being close; and
a transmission step during which the processor sends the report from the aircraft to a ground installation via the transmitter;
wherein the threshold values are dynamically adapted according to medium or long term base turbulence levels, encountered by the aircraft, in order to limit incorrect detections.

Abstract
A method to identify the proximity of a wake turbulence and to generate a report relative to that proximity. A method implemented by an aircraft comprising a processor makes it possible to identify the proximity of a wake turbulence and to generate a report relative to that proximity. The method includes a data acquisition step during which the processor retrieves and records the data relative to each generating aircraft present around the aircraft. In a position estimation step, the processor estimates the position of the wake turbulences generated by each generating aircraft. In a proximity step, the processor determines if the aircraft is close to at least one of the wake turbulences. In a generation step, the processor generates a report containing the data relative to each wake turbulence. The method makes it possible to identify the proximity of a wake turbulence in the vicinity of the aircraft and to automatically record the data relative to that wake turbulence.
