A winglet system for a wing of an aircraft is provided. The winglet system comprises an attachment end for attachment to a main wing of the aircraft, an upper winglet and a lower winglet. The upper and lower winglets are staggered and also overlap one another along the chord of the attachment end. A spanwise profile of the lower winglet has a midpoint where a slope of the spanwise profile at a point outboard of the midpoint is inclined more upwardly than a slope of the spanwise profile at the midpoint. The configuration of the winglet system may provide benefits such as a reduced bending moment and reduced negative interference between the winglets while also managing ground clearance.
