On fixed-wing aircraft, the angle of incidence (sometimes referred to as the mounting angle) is the angle between the chord line of the wing where the wing is mounted to the fuselage, and a reference axis along the fuselage (often the direction of minimum drag, or where applicable, the longitudinal axis). The angle of incidence is fixed in the design of the aircraft, and with rare exceptions, cannot be varied in flight
I believe this question is too generical. We have to many angles to determine a wing and both winga re the same. For istance: Angle of attach ( both wings) Inbord attach angle of the wing ( Upper and lower connection on the fuselage, both wings) Angle of incidence and so on
