How long must evacuation slides with gray coatings resist flame exposure according to FAA standards?

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

Answer: (C)

Evacuation slides with gray coatings must resist flame exposure for 90 seconds according to FAA standards. This requirement is critical to ensure passenger safety during emergencies. The 90-second duration allows sufficient time for the safe evacuation of passengers and crew from an aircraft in the event of a fire.

The flame resistance of the materials used in the slides helps to ensure they remain functional and do not contribute to the fire hazard during an emergency evacuation. By maintaining structural integrity for 90 seconds, the slides provide reliable escape routes, giving occupants crucial time to exit the aircraft safely. This standard reflects the FAA's commitment to enhancing safety protocols in the aviation industry.
