What command will flight attendants hear after turbulence when it is safe to move about the cabin?

The command that flight attendants typically hear after turbulence, indicating that it is safe to move about the cabin, is one that explicitly informs them of their ability to resume service and other normal activities. In this context, the correct answer is often one that explicitly mentions that flight attendants can now move about or engage in service.

The command stating "Flight attendants, you may proceed with service" clearly indicates that it is safe for the flight attendants to leave their jumpseats and begin their service duties again after the turbulence has passed. This command is crucial as it provides the necessary assurance that the conditions in the cabin have stabilized.

Other options such as “take your jumpseats” would indicate a need for immediate compliance with safety protocols due to ongoing turbulence, while a command like "check in" does not specifically address the ability of the crew to engage with passengers or resume activities. Similarly, "resume normal duties" might imply a broader range of operations but lacks the explicit context required immediately after turbulence that reassures flight attendants about the safety of moving around the cabin.
