The goal of any evacuation is to remove all occupants from the aircraft within how many seconds?

• A. 60 seconds
• B. 30 seconds
• C. 90 seconds
• D. 120 seconds

Answer: (C)

Evacuation time measures how quickly everyone can get off the airplane in an emergency. The standard target is to remove all occupants within ninety seconds, using the available exits. This goal ensures crew actions, door operations, and slide deployments happen fast enough to reduce exposure to hazards like smoke or fire, while still being achievable given the mix of passengers and their responses. Times shorter than this would be unrealistic for typical crowd movement and exit operation, while longer times would leave people in danger longer than necessary. Ninety seconds provides a practical safety margin that pilots and cabin crew train to meet during evacuations.
