What type of power is used to operate windshield wiper systems?

Windshield wiper systems in aircraft typically use electrical or hydraulic power to operate effectively. Electrical wiper systems utilize motors powered by the aircraft's electrical system, providing reliable operation and control over the wiper speed and movement. Hydraulic-powered wipers, although less common, leverage hydraulic fluid pressure for operation, which can be particularly useful in larger aircraft where hydraulic systems are already in place for other functions.

This approach ensures that the wipers can perform efficiently in various weather conditions, maintaining visibility for the pilots. Other methods, such as manual operation or the use of solar or compressed air, are less practical or less efficient for the needs of modern aviation equipment, making electrical or hydraulic systems the preferred choice.
