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

What is the minimum altitude for deploying flight spoilers?

1. 500 feet

2. 1000 feet

3. 1500 feet

4. 2000 feet

The correct answer is: 1000 feet

The minimum altitude for deploying flight spoilers is typically set at 1000 feet above ground level. Spoilers are aerodynamic devices used to reduce lift and increase drag, assisting pilots in controlling the aircraft during various phases of flight. Deployment at this altitude ensures that sufficient airflow over the wings allows for effective functioning of the spoilers, maintaining aircraft control. Furthermore, deploying spoilers below this altitude could compromise the aircraft's lift capabilities, particularly during critical phases such as approach and landing, where maintaining precise altitude and control is essential for safety. Understanding this operational threshold is crucial for pilots to optimize performance while ensuring safety during descent and approach.
