Abstract
A piloting assistance method for avoiding an obstacle with a rotorcraft flying along a current speed vector (Vect). An alert is generated by using a speed vector of the rotorcraft referred to as a 'calculation' speed vector (Vect) in order to determine whether the rotorcraft might impact an obstacle. During a correction stage and at each calculation iteration, the calculation speed vector (Vect) is determined using a horizontal component and a vertical component, the vertical component being a function of a current vertical speed of the rotorcraft relative to the ground corrected with a corrective term, the corrective term being a function of a product of a current path speed of the rotorcraft multiplied by the derivative of the path speed.
