The angle of incidence in aircraft design refers to the angle at which an aircraft’s wing or other lifting surfaces are attached to its fuselage or body. It is the angle between the longitudinal axis of the aircraft (the centerline running from nose to tail) and the chord line of the wing or lifting surface.
The formula to calculate the angle of incidence is straightforward:
There is no mathematical formula needed to calculate this angle because it is a geometric property of the aircraft’s design.
