What are ground boarding stairs used for?

• A. Loading cargo
• B. Boarding and deplaning passengers
• C. Parking ground service vehicles
• D. Providing emergency exits

Answer: (B)

Ground boarding stairs are specifically designed to facilitate the boarding and deplaning of passengers from an aircraft, particularly when the aircraft is parked away from a jet bridge or passenger terminal. This equipment allows for a safe and efficient way for passengers to access the aircraft directly from the tarmac.

Using ground boarding stairs ensures that passengers can embark and disembark with minimal difficulty, providing enough height and access to match the aircraft door. While cargo loading, parking vehicles, and emergency exits are essential aspects of airport operations and safety, they do not align with the primary function of boarding stairs, which is exclusively focused on passenger movement.
