WINDSHIELD WIPER SYSTEM – GENERAL
The purpose of the windshield wiper system is to keep the windshield
surface clean from water, dirt, sand, dust or a thin coat of soft snow.
The system consists of two identical installations, one for the pilot windshield
and the other for the copilot windshield and allows the operation of the pilot
and copilot wiper blades separately or together.
