When the sterile flight deck light is illuminated, the flight deck should be contacted for what type of items?

• A. Only safety-related items
• B. Routine announcements
• C. Medical emergencies
• D. Weather updates

Answer: (A)

The sterile flight deck light indicates that only information directly affecting safety should be communicated to the pilots. Keeping the cockpit disturbance-free during critical phases helps pilots stay focused on flying the aircraft and handling any safety-critical issues that arise. So, messages should be limited to items that have a direct impact on safety—things like a potential system fault that could affect flight control, security concerns, or other urgent safety-related matters. Routine announcements, weather updates that aren’t immediately relevant to the current safety of the operation, or non-urgent information should be deferred until the sterile period ends. A medical emergency would be treated as safety-related if it could affect the flight’s safe operation, and would therefore be communicated when necessary to ensure safety.
