During which periods should cabin crew restrict communication with the flight deck except for safety issues or emergency situations?

• A. During all phases of flight
• B. During taxi, take-off, initial climb, approach, landing, and any phase below 10,000 feet.
• C. There are no restrictions.
• D. Only during turbulence.

Answer: (B)

The key idea is the sterile cockpit concept: during high-workload or critical phases of flight, nonessential communication with the flight deck should be minimized so pilots can focus on the task at hand. This means cabin crew should only raise safety-related issues or emergencies during those times. The periods specified—taxi, take-off, initial climb, approach, landing, and any phase below 10,000 feet—are exactly when pilots are busiest with configuration, engine and flight controls, and speed/trajectory management. Limiting nonessential chatter during these times helps prevent distraction and reduces the chance of miscommunication. The other options don’t fit because they either push restrictions too broadly (all phases of flight) or not at all (no restrictions), or they narrow the restriction to turbulence alone, which is not the standard scope.
