1. A control surface arrangement for an aircraft, comprising:
a first and a second control surface element each having convexly curved outer surfaces and being arranged side by side in a spanwise direction with a gap therebetween, wherein the gap is covered by a sealing strip comprising:
a convexly curved outer side,
welting sections at both longitudinal edges of the sealing strip for fixing the sealing strip at the first and the second control surface elements, and
a mid-seal section between the welting sections,
wherein the welting sections protrude on an inner side from the mid-seal section,
wherein the sealing strip has a first length region, a second length region, and a third length region, the second length region being located longitudinally of the sealing strip between the first and third length regions,
wherein the welting sections are omitted in the second length region or the welting sections in the second length region are less rigid than the welting sections in the first and third length regions,
wherein the second length region is arranged in an area of the control surface arrangement with a strongest curvature or a smallest curvature radius.
