How much time do we have to fully evacuate an aircraft?

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

Answer: (C)

The main idea here is the safety standard for evacuating an aircraft. In training and certification, crews are expected to evacuate all passengers within 90 seconds from the moment the alarm sounds, using every available exit. This 90-second benchmark is chosen because it provides a balance between speed and practicality, helping to minimize exposure to smoke, heat, and potential fire after an emergency. Practically, you learn to coordinate with the crew, deploy slides where needed, and guide passengers efficiently through doors and over-wing exits to reach safety quickly. Other times—faster or slower—don’t align with the established safety standard, which is why 90 seconds is the accepted target.
