What action is implied when the PA 'Emergency Descent' is heard three times?

• A. The aircraft will perform an emergency descent
• B. The flight deck will reprogram the route
• C. The cabin crew will initiate landing procedures
• D. Passengers should brace for turbulence

Answer: (A)

Hearing the Emergency Descent spoken three times is a clear, urgent directive to start an immediate, rapid descent to a lower altitude. The repetition is used to cut through noise and ensure everyone on board—crew and passengers—recognizes the seriousness and acts quickly. This instruction is about changing altitude quickly to reach a safer atmospheric and cabin-condition, not about changing the flight plan or preparing for landing, nor about bracing for turbulence. The proper response is that the aircraft will descend promptly to a safer, lower level.
