What is the purpose of windshield wipers and rain repellent during low visibility?

Maintaining visibility is the goal when visibility is reduced. Windshield wipers physically sweep rain, mist, and spray from the windshield, restoring a clear line of sight for the pilot. Rain repellent changes how water behaves on the glass by increasing beading and runoff, which reduces smear and streaking between wipes. Together, they help you see the runway, instruments, and other traffic more clearly in rain or fog, improving safety. They don’t affect engine performance, protect from hail, or change radio reception.
