What happens to the ground spoilers if the over-wing exit is opened?

• A. They retract into the wing
• B. They remain in the down position
• C. They rise up to reduce drag
• D. They are disabled automatically

Answer: (B)

When the over-wing exit is opened, the ground spoilers remain in the down position. This is important for aircraft safety and performance. The primary function of ground spoilers is to disrupt the airflow over the wing and increase drag during landing, helping to decelerate the aircraft. If the over-wing exit is used, it indicates an evacuation situation where maintaining control over the aircraft's aerodynamic behavior is crucial. Keeping the spoilers deployed ensures that the aircraft remains stable and does not lift off unexpectedly, providing a safer environment for passengers and crew during the emergency egress.

This feature is designed to ensure maximum drag remains in effect, reducing the risk of injury or further danger during an evacuation scenario. The other scenarios, such as retracting the spoilers or them rising to reduce drag, would not be appropriate responses in an emergency and could compromise safety. Disabling them automatically might also lead to a loss of control, which is undesirable in an emergency evacuation context.
