What is one of the key responsibilities during No.3 PDIs?

One of the key responsibilities during No.3 Pre-Delivery Inspections (PDIs) is ensuring cabin service is stocked. This task is crucial for maintaining operational efficiency and passenger satisfaction. When cabin service items such as food, beverages, and emergency supplies are adequately stocked, it ensures that the crew can meet the needs of passengers efficiently, leading to a smoother flight experience.

In the context of flight operations, stocked cabin service is essential as it allows for proper service delivery throughout the flight. If the cabin is lacking necessary items, it could lead to delays, dissatisfaction among passengers, and create potential safety concerns should an emergency arise where supplies are needed.

Other responsibilities such as checking boarding pass accuracy and luggage may be important, but they pertain more to the boarding process rather than the specific duties associated with ensuring that the cabin is prepared for service. Pre-flight crew briefing is also critical but focuses more on communication and safety rather than the direct readiness of cabin supplies. Checking hand luggage is relevant to security and compliance, yet it falls outside the specific scope of stocking cabin service during PDIs.
