Abstract
An aircraft tail surface, such as a horizontal tail plane or a vertical tail plane, including a leading edge having, in at least a section along the tail span, an undulated shape formed by a continuous series of smooth protrusions and recesses so that, in icing conditions, the ice accretion is produced only on the peaks of the protrusions and on the bottoms of the recesses, thereby creating a channeled airflow and an arrangement of air vortices which impart energy to the airflow in the aerofoil boundary layer which delay the airflow separation that causes the stall, thus reducing the detrimental effects of ice accretion in its aerodynamic performance.
