A gurney flap arrangement comprising: an airfoil (2) with a trailing edge (6) and an opening (14) in a surface (8) of the airfoil (2); a gurney flap (1) having a first position in which at least a portion of the gurney flap (1) extends through the opening (14) and projects outwardly from the airfoil surface (8), and a second position in which the gurney flap (1) does not project from the airfoil surface (8) or projects outwardly from the airfoil surface (8) to a lesser extent; and a gurney flap actuator (3) for moving the gurney flap (1) between at least the first position and the second position. The gurney flap actuator (3) is arranged to move the gurney flap (1) in a direction that extends along an inclined angle with less than 90 degrees between the gurney flap (1) and a part of the airfoil surface (8) extending from the opening (14) toward the trailing edge (6) such that when moving from the second position into the first position a distal edge (16) of the gurney flap (1) moves both outward from the airfoil surface (8) and also in a direction extending along the airfoil surface (8) toward the trailing edge (6).
