What is the maximum speed for windshield wiper operations in the CRJ 900/700?

The maximum speed for windshield wiper operations in the CRJ 900/700 is indeed 250 KIAS. This limitation is important for ensuring the effective and safe use of the windshield wipers under various flight conditions. Exceeding this speed could potentially lead to damage to the wipers or result in inadequate performance, such as reduced visibility in adverse weather conditions.

In the context of operational safety and aircraft design, this limit helps the pilots maintain optimal visibility and prevents any mechanical strain on the wiper system that could occur at higher speeds. Thus, understanding this limitation is critical for flight preparation and ensuring the wipers function effectively when needed during flight operations.
