What is the purpose of the windscreen wipers on the EJet?

The windscreen wipers on the EJet serve a critical function by maintaining visibility during rain or adverse weather conditions. Effective visibility is essential for safe flying operations, and during periods of precipitation, the accumulation of water on the windscreen can obstruct a pilot's view. The windscreen wipers actively remove this water, allowing the pilot to see clearly outside the aircraft. This is particularly vital during takeoff, landing, and taxiing when visibility can significantly affect safety.

While other options mention clearing ice or aesthetics, those do not accurately define the primary purpose of the wipers, and reflecting sun's glare is not a function associated with windscreen wipers. Overall, the primary goal of the windscreen wipers is to ensure the pilot can maintain visual awareness of their environment, thus allowing for safe navigation through varying weather conditions.
