What action does the aircraft take immediately after a decompression event?

• A. Steep descent
• B. Sharp climb
• C. Maintain flight level
• D. Stop the aircraft

Answer: (A)

After a decompression, the priority is to restore breathable air as quickly as possible. The aircraft initiates an emergency descent, quickly lowering the cabin altitude to about 8,000–10,000 feet (often targeted as 10,000 feet or lower) so everyone can breathe normally again and the risk of hypoxia decreases. Climbing or staying at the current altitude would keep the cabin at an unsafely high altitude with insufficient oxygen, so that isn’t appropriate. Stopping the aircraft isn’t a standard maneuver for this situation and wouldn’t address the immediate oxygen deficit.
