What is the crew’s expected response during a depressurization event?

• A. Don oxygen masks immediately, follow crew commands, secure passengers, and descend to a breathable altitude as directed.
• B. Remain seated and wait for the purser to give instructions.
• C. Open window exits to equalize pressure before donning masks.
• D. Contact air traffic control to declare an emergency before acting.

Answer: (A)

During a depressurization, the immediate priority is to provide oxygen to yourself and the passengers and to move to an altitude where breathable air is available, while maintaining orderly control of the cabin. Don oxygen masks immediately, follow crew commands, secure passengers, and descend to a breathable altitude as directed. Providing oxygen without delay preserves cognitive function and time is critical as the cabin loses pressure. Keeping passengers seated with seatbelts fastened and guiding them through the procedure helps prevent panic and injuries, then descending to the indicated safe altitude ensures everyone remains in a survivable environment. Opening window exits is unsafe and not how depressurization is managed; attempting to equalize pressure this way can cause dangerous rapid decompression and harm. Waiting for the purser or contacting air traffic control before acting would delay essential protective actions—the crew will coordinate communications and responses once the immediate safety steps are underway.
