The wing dihedral is the upward angle of the aircraft’s wings from the wing root to the wing tip. Having the wings designed to have an upward angle makes the aircraft more stable. If the wings had no dihedral then the aircraft would continue in this direction unless the pilot corrected the bank. Dihedral Aspect ratio refers to the length and width of an aircraft wing. A short wide wing has a ‘low aspect’ ratio, while a long thin wing has a ‘high aspect’ ratio. Aspect ratio Camber is the amount of curve from the leading edge to the trailing edge. More camber normally results in a thicker wing. The more camber the more lift the aerofoil produces. More camber also results in more drag. This is one reason why high performance aircraft do not have much camber, so they can minimise drag. Camber Sweepback is the angle of the wing that slopes back from the aircraft fuselage. Usually higher performance aircraft have swept wings, this is due to reduced drag at higher speed with a swept wing. Sweepback Design features Ch.2 - How an aircraft generates lift
