What must a flight attendant do to communicate with the flight deck during normal operations?

To communicate effectively with the flight deck during normal operations, a flight attendant must remove the handset and press the FLT button. This specific action directly connects the flight attendant to the flight crew, allowing for clear communication regarding non-emergency situations.

The use of the intercom for normal communication is an established procedure to ensure that both the cabin and flight deck personnel can relay information efficiently. This method is preferred because it allows for immediate and direct communication without the need for additional steps or procedures that might delay the conversation.

Activating the emergency call button or using other less direct forms of communication would not be appropriate during routine operations as they are typically reserved for urgent situations. Therefore, the choice to use the FLT button reflects the standard protocol for ensuring that both the cabin and flight deck are coordinating effectively in their operational functions.
