Abstract
An aircraft steering angle control system is provided that minimizes the amount of skidding of an airframe that is turning on a low-μ taxiway surface, such as an icy taxiway surface, and allows for directional control of the airframe by a steering command. The aircraft steering angle control system outputs an operation signal related to a steering angle as a control command signal for a nose steering wheel, and includes: a nose steering wheel envelope protection function including a reference steering angle setting unit that calculates a reference steering angle on the assumption that the airframe is not skidding; a skid detection unit that detects a skidding state of the airframe based on the reference steering angle; and a switch unit that selects a control command signal for the nose steering wheel in conjunction with the skid detection unit.
