What is the standard crew action if the cabin experiences rapid depressurization?

• A. Rely on passengers to neutralize the pressure.
• B. Don oxygen, secure everyone, and follow the decompression checklist while instructing passengers to don their masks.
• C. Descend to a safe altitude and await instructions.
• D. Continue service normally.

Answer: (B)

When rapid depressurization occurs, the immediate priority is to get oxygen to everyone and establish control of the situation. The crew should don their own oxygen masks right away, secure all passengers (seat belts fastened, crew at their stations), and perform the decompression checklist. Instructing passengers to don their masks ensures they receive oxygen as quickly as possible, which is essential for maintaining judgment, communication, and overall safety. The checklist guides you through the required steps in a proven order, including managing the cabin and, as soon as practical, descending to a safe altitude. Waiting for instructions or continuing normally would delay critical actions and increase the risk of hypoxia for everyone aboard.
