Method and device for assisting the initiation of a flare maneuver of an aircraft during a landing of the aircraft

A method for assisting initiation of a flare maneuver of an aircraft, during a landing of the aircraft, the method comprising at least a series of steps as follows, implemented during a descent of the aircraft during the landing:

• an acquisition step, implemented by at least one acquisition unit and comprising acquiring in real time current values of flight parameters of the aircraft, including current height of the aircraft with respect to the ground;
• a first computation step, implemented by a first computation unit and comprising computing, in real time, a current start of flare height, on a basis of acquired current values;
• a second computation step, implemented by the computation unit and comprising computing, in real time, at least a first height and a second height called reference heights, the first reference height corresponding to a height starting from which the aircraft attains the current start of flare height while maintaining its current descent conditions over a first predetermined duration, the second reference height being less than the first reference height and corresponding to a height starting from which the aircraft attains the current start of flare height while maintaining its current descent conditions over a second predetermined duration;
• a third computation step, implemented by a third computation unit and comprising determining, in real time, a time at which the current height of the aircraft attains the first reference height during the descent and the time at which the current height of the aircraft attains the second reference height during the descent;
• and
• an acoustic emission step, implemented by an acoustic emission unit and comprising emitting at least two sound signals in a cockpit of the aircraft, including a first sound signal when the current height of the aircraft attains the first reference height during the descent and a second sound signal when the current height of the aircraft attains the second reference height during the descent.
