When is the sterile light illuminated?

When is the sterile light illuminated?

• A. During takeoff
• B. During turbulence
• C. During critical phases below 10,000 feet
• D. During landing

Answer: (C)

The sterile light comes on to signal the cockpit is in sterile mode, meaning nonessential talk and activities should be kept to a minimum because you’re in critical phases of flight and must stay focused. This regime is defined for all the high-workload periods, typically below 10,000 feet, including taxi, takeoff, approach, and landing. So the light is illuminated during those critical phases below 10,000 feet, not just during turbulence or any single phase alone.
