During sterile flight deck conditions, the Captain can be contacted under what circumstance?

• A. For routine messages
• B. In case of Safety
• C. For non-safety matters
• D. At the crew's discretion

Answer: (B)

Sterile flight deck conditions are meant to minimize distractions for the flight crew during critical phases of flight, so only communications that affect safety or flight deck operations are allowed. Because of that, the Captain should be contacted only for safety matters—things that could impact the safety of the aircraft or require the Captain’s immediate judgment. Routine messages, non-safety topics, or casual inquiries do not fit this moment and should wait until the sterile conditions are lifted. When a safety issue does arise, use the cockpit interphone and follow the established procedure to alert the Captain promptly. This approach keeps the crew focused where it matters most and ensures a quick, appropriate response to hazards.
