A windshield wiper system (1) for an aircraft is provided and includes a motor (2), an output shaft (5), a wrap spring and crank rocker mechanism (WSCRM) (10) to which the motor (2) and the output shaft (5) are coupled and a controller (3). By way of the WSCRM (10), first directional rotation input to the WSCRM (10) from the motor (2) via a two-stage gear reduction is converted such that the output shaft (5) drives wiper blade oscillation through a first sweep angle and second directional rotation input to the WSCRM (10) from the motor (2) is converted such that the output shaft (5) drives wiper blade oscillation through a second sweep angle. The controller (3) is configured to control the motor such that the first directional rotation is continuously or non-continuously input during first or second flight conditions, respectively, and the second directional rotation is continuously input during third flight conditions.
