Ryanair Conversion 4 Practice Test

When a depressurization occurs, the immediate priority is to restore breathable air and reduce the crew’s exposure to high-altitude conditions. Oxygen should be donned right away by the crew to maintain consciousness and situational awareness. At the same time, the aircraft should initiate a rapid descent to a safe altitude where cabin pressure can be maintained without auxiliary oxygen for passengers. Declaring an emergency to ATC and requesting priority handling or a diversion helps ensure a safe routing and access to emergency services if needed. This combination—putting on oxygen, descending to a breathable altitude, and coordinating with ATC—is the safest and most effective response.

Continuing to climb, delaying oxygen until passengers complain, or maintaining altitude and ignoring oxygen would all leave the crew and passengers in a dangerous, hypoxic situation.
