Abstract: A system (40) for controlling a ground lateral trajectory of an aircraft includes a command module (120) configured to generate a command of an instruction lateral trajectory, a limiting module (58) configured to determine, as a function of a speed and a maximum authorized sideslip angle of the wheel (5) of the aircraft, a steering angle range of the wheel (5) such that, the steering angle of the wheel (5) being in this range, the steering angle of the wheel (5) is smaller than the maximum steering angle, and a control module (130) configured to determine, as a function of the command, an instruction steering angle included in the range and able to cause a lateral movement of the aircraft according to or tending toward the instruction trajectory, and to send a steering instruction to the wheel (5) in order to orient it along the instruction angle.

Abstract: A system for controlling a lateral trajectory of an aircraft includes a rudder bar. Each pedal of the rudder bar is movable between a neutral position (pn) and an end-of-travel position (pf) along a unique travel. A movement of the pedal between the neutral position (pn) and an activation position (pact) commands a lateral movement by actuating a lateral movement device of a first set including a nose gear wheel, the different braking of the aircraft being nonactive. A movement of the pedal from the activation position (pact) to the end-of-travel position (pf) commands a lateral movement by actuating a device of the first set and the differential braking. A haptic feedback generator applies a first haptic profile to each pedal between the neutral position (pn) and the activation position (pact) and a second haptic profile from the activation position (pact) toward the end-of-travel position (pf).
