PSA Airlines Canadair Regional Jet Systems (PSA-CRJ) Practice Exam

Do the Spoilerons and Flight Spoilers operate in tandem on the applicable side?

1. False

2. True

3. Only in low speed

4. Only during landing

The correct answer is: True

The statement that the Spoilerons and Flight Spoilers operate in tandem on the applicable side is true. In the design of the Canadair Regional Jet (CRJ) system, Spoilerons are integrated with the flight spoilers to enhance roll control, especially at higher speeds. When the aircraft requires roll authority, the spoilerons deploy in conjunction with flight spoilers on the same side, providing additional roll effectiveness and stability during flight. This tandem operation is particularly beneficial during various phases of flight, such as turns or when adverse yaw occurs, allowing for smoother and more controlled maneuvers. The joint operation helps to optimize aircraft performance by effectively managing lift and drag, ensuring the aircraft maintains controlled flight while enhancing the pilot's ability to maneuver the aircraft efficiently. Other options do not accurately describe the operational dynamics between Spoilerons and Flight Spoilers. For instance, claiming that they operate only at low speed or only during landing ignores the broader applicability of their functionality throughout various flight conditions where roll control is necessary.
