Is it safe to enter the crew rest area if the Air Flow OFF light is not illuminated?

• A. True
• B. False
• C. Not enough information
• D. Only with supervisor approval

Answer: (A)

The airflow indicator is there to confirm ventilation in the crew rest area. When the Air Flow OFF light is lit, ventilation is off, so entering would not be safe. If that indicator is not illuminated, the environmental control system is providing airflow, meaning the crew rest area is ventilated and it’s safe to enter under normal conditions. If there’s any doubt about airflow status, verify at the environmental controls panel or consult a supervisor before entry.
