What typically happens to cabin pressure during descent?

• A. The pressure increases rapidly
• B. The outflow valves are adjusted to avoid rapid changes
• C. The cabin ceiling fans turn off
• D. Emergency oxygen masks are deployed

Answer: (B)

During descent, the management of cabin pressure is crucial for passenger comfort and safety. Typically, outflow valves are actively adjusted to regulate the outflow of air from the cabin. This adjustment ensures that the rate of pressure change is gradual and avoids rapid fluctuations that could be uncomfortable or even harmful to those onboard. By gradually releasing cabin air as the aircraft descends, the outflow valves help maintain a controlled cabin environment, preventing sudden pressure changes that could lead to ear discomfort or barotrauma. This careful regulation of cabin pressure is a standard procedure during descent, ensuring that passengers experience a smooth transition as the aircraft approaches lower altitudes. The other aspects mentioned in the answer choices, such as cabin pressure increasing rapidly, fans turning off, or oxygen masks deploying, do not accurately reflect the typical management of cabin pressure during descent. Hence, the operation and adjustment of outflow valves is the correct and most relevant action regarding cabin pressure changes during this phase of flight.
