What is the maximum airspeed for windshield wiper operation on the ERJ 170/175?

The maximum airspeed for windshield wiper operation on the ERJ 170/175 is 250 KIAS. This limitation is crucial because exceeding this speed can lead to potential damage to the wiper system due to aerodynamic forces acting on the components. Operating the wipers at speeds greater than this can increase the risk of failure or reduced effectiveness, particularly in adverse weather conditions where visibility is already compromised. Understanding these limitations is essential for safe operation and to ensure that the flight crew can maintain optimal visibility during varied flight conditions.
