Angle of Incidence is a/an (mechanical / aerodynamic) angle.

Explanation:
Angle of incidence is a fixed geometric orientation: the angle between the wing’s chord line and the aircraft’s longitudinal axis. It is a mechanical setting established by the aircraft’s design (or adjusted during maintenance) and does not change with flight conditions. This distinguishes it from the aerodynamic angle of attack, which is the angle between the chord line and the relative wind and varies with speed, attitude, and flight regime. Because incidence describes a built-in, structural orientation of the aircraft, it is classified as a mechanical angle.
