Which action does not require cross-flight deck communication and acknowledgement when changes are made to flight deck information or equipment?

• A. Adjusting information on the flight deck
• B. Selection of cabin temperature
• C. Replacing a flight deck instrument
• D. Reconfiguring the flight plan

Answer: (B)

The key idea is when changes to flight deck information or equipment require verification and acknowledgment between the crews. Actions that alter what the flight deck uses, or the hardware it relies on, demand cross-deck communication to keep everyone aligned and aware of the updated state. Selecting cabin temperature is a cabin-control function that does not modify flight deck data or equipment. It’s managed by cabin crew and stays within the cabin domain, so it doesn’t trigger cross-flight deck communication or require acknowledgement from the flight crew. In contrast, adjusting information on the flight deck changes the data the flight crew relies on, replacing a flight deck instrument changes the actual hardware the flight deck uses, and reconfiguring the flight plan alters routing and navigation data. All of these require formal communication and mutual acknowledgement to ensure both decks have the same, updated information and equipment status.
