Incidence on Wing Calculator

“Incidence” in the context of aircraft design and aerodynamics refers to the angle at which a wing or other aerodynamic surface is set relative to the aircraft’s fuselage or reference axis. It’s a crucial parameter that affects the wing’s lift and drag characteristics, as well as the overall aerodynamic performance of the aircraft.

The formula for calculating the incidence angle ($\alpha$) on a wing is straightforward:

• $\alpha$ is the incidence angle (typically in degrees or radians).
• “Wing Chord Line Angle” is the angle of the chord line of the wing relative to a reference axis (e.g., the longitudinal axis of the aircraft).
• “Fuselage Reference Line Angle” is the angle of a reference line on the fuselage (e.g., the longitudinal axis of the aircraft) relative to a fixed reference axis.
