Secondary means of aircraft egress.

• A. Ground Evacuation
• B. Escape Slides/Slide raft
• C. Crew Entrance Door
• D. Escape Ropes

Answer: (D)

Secondary means of egress are backup exits used when the primary exit system isn’t available. The usual primary method is through the main doors that deploy escape slides or slide rafts. Escape ropes are stored at selected exits and provide a manual, rope-assisted way to get out when slides can’t be deployed or the door can’t be opened. They’re designed for rapid egress from openings such as cockpit escape hatches or other overhead/window-style exits, allowing evacuees to descend to the ground or water. Ground evacuation and the crew entrance door describe different parts of the overall process or primary exits, so escape ropes fit the role of the secondary option.
