What equipment must include a demo extension, mask, and life vest during preflight checks?

• A. They all must be in place
• B. They can be partially available
• C. They can be stored in different locations
• D. They are not necessary for the flight

Answer: (A)

The requirement for a demo extension, mask, and life vest to be included during preflight checks ensures that all essential safety equipment is readily accessible and in proper working condition before a flight. This safety protocol is crucial because it prepares the crew to demonstrate the use of safety equipment to passengers and ensures that in the event of an emergency, all necessary gear is available and can be quickly utilized.

Having all items in place signifies that safety measures are prioritized, which contributes to a safer flight environment. This approach is consistent with aviation regulations that emphasize the importance of readiness and proper equipment configuration before takeoff, ensuring compliance with safety standards and protocols.
