What do the ice and rain protection systems in the CRJ do?

• A. They enhance fuel efficiency
• B. They prevent ice accumulation and ensure clear visibility
• C. They facilitate faster cruise speeds
• D. They regulate cabin temperature

Answer: (B)

The ice and rain protection systems in the CRJ are primarily designed to prevent ice accumulation on critical surfaces of the aircraft and to maintain clear visibility for the flight crew in adverse weather conditions. When ice forms on the wings, tail, or control surfaces, it can significantly alter the aerodynamic properties of the aircraft, potentially leading to a decrease in lift and an increase in drag. Additionally, ice can obstruct sensors and windows, which is vital for safe flying. The systems include surface heaters, which keep the wings and tail clear of ice, and de-icing components that help manage water and ice on notable surfaces, ensuring safety and operational effectiveness during flight in icing conditions. Clear visibility is also crucial, as rain and other precipitation can impair the pilots' ability to see outside, so rain protection enhances the effectiveness of windshield wipers and heating elements. This focus on preventing ice and ensuring visibility is the core function of these systems, differentiating them from attributes related to fuel efficiency, cruise speeds, or cabin temperature regulation.
