1. A method for detecting the presence of a crosswind for a turbomachine of an aircraft, the aircraft including at least two turbomachines disposed on either side of a main axis of the aircraft extending between a nose of the aircraft and a tail of the aircraft, said turbomachines each including a low-pressure shaft, a low-pressure compressor coupled to said low-pressure shaft, and a set of at least three sensors for controlling the operation of the turbomachine, a first sensor of the set being configured to measure a speed of the low-pressure shaft, a second sensor of the set being configured to measure a first pressure or temperature upstream of the low-pressure compressor of the turbomachine with respect to the direction of the air flow in the turbomachine, and a third sensor of the set being configured to measure a second pressure or temperature downstream of said low-pressure compressor with respect to the direction of the air flow in the turbomachine,
the method comprising the following steps:
for each turbomachine, acquiring the data of the set of at least three sensors,
for each turbomachine, normalizing said first pressure or temperature of a turbomachine with respect to the speed of the low-pressure shaft and with respect to the second pressure or temperature,
comparing the normalized first pressure or temperature of a turbomachine with the normalized first pressure or temperature of said at least one other turbomachine engine of the aircraft,
detecting the presence of a crosswind based on the result of the comparison.
