What is the function of a barrier strap in an airplane setting?

• A. To close an emergency exit
• B. To secure the cabin crew in an emergency
• C. To hold a door open when a jetbridge is not present
• D. To hang safety equipment

Answer: (C)

The function of a barrier strap in an airplane setting is primarily to hold a door open when a jetbridge is not present. This is important for facilitating the boarding and deplaning of passengers, ensuring that the door remains safely secured in the open position while allowing for easy access to and from the aircraft. Barrier straps help prevent the door from accidentally closing, which could create hazards for passengers and crew members during these operational phases.

In contrast, while emergency exits must be managed, barrier straps are not specifically designed to close them. Additionally, securing cabin crew members in emergencies involves other safety equipment and measures rather than barrier straps. Furthermore, barrier straps are not intended for hanging safety equipment, as their primary role is related to door management during passenger transitions.
