What is the standard evacuation target time for all occupants from the aircraft?

• A. 60 seconds
• B. 120 seconds
• C. 90 seconds
• D. 150 seconds

Answer: (C)

The standard evacuation target time is the maximum duration allowed for everyone on board to exit the aircraft after the alarm sounds. This benchmark, 90 seconds, is used in certification and training to ensure the aircraft can be evacuated quickly and safely in an emergency, even with the crew directing people and passengers moving through aisles and toward the exits. The goal is to demonstrate that all occupants can be off the aircraft within 90 seconds, which is why this option is the best choice. Times shorter than that (like 60 seconds) are not the regulatory standard, and longer times (120 or 150 seconds) exceed the required target.
