Composite wing edge attachment and method

A composite fixed edge of an aircraft wing, comprising:

• a composite wing box skin panel, attached to an outward wing spar in an attachment region, with an overhanging edge, having a substantially constant thickness and ply count in the attachment region, the overhanging edge being without any joggle;
• and
• a composite ramp, upon an outer surface of the composite wing box skin panel, having a proximal end and a distal end, the composite ramp being thicker at the distal end than at the proximal end, the distal end being set back from the overhanging edge, defining a shoulder on the overhanging edge, wherein the composite ramp is formed of a plurality of composite plies;
• and
• a composite wing edge skin panel, having a thickness substantially equal to a maximum thickness of the composite ramp, attached to the composite wing box skin panel at the shoulder and adjacent to the distal end of the composite ramp,
• wherein the shoulder has a relief radius between the shoulder and the outer surface of the composite wing box skin panel.
