Lifting surface (1) of an aircraft, comprising a leading edge (2) and a notch (3) located in said leading edge (2), the notch (3) comprising two walls (6) adapted to be parallel to the direction of the incident flow to the lifting surface (1) and a third wall (5) adapted to face the incident flow to the lifting surface (1) when it is in flight. The lifting surface (1) also comprising a retractable cover element (4), the notch (3) and the retractable cover element (4) being configured such that when the retractable cover element (4) does not cover the notch (3), said notch (3) is exposed to the incident flow generating a vortex which increases the lift force of the lifting surface, delaying stall.
