What button would the FWD flight attendant press to communicate with the AFT flight attendant on the CRJ 700?

The FWD flight attendant would press the ATT button to communicate with the AFT flight attendant on the CRJ 700. This button is specifically designed for intercom communication between flight attendants. When the FWD flight attendant presses the ATT button, it sends a direct call to the AFT flight attendant's station, allowing for immediate and clear communication.

This is crucial during in-flight operations where quick communication is necessary for coordination regarding passenger needs, safety concerns, or other critical situations. The function of the ATT button provides a reliable means of ensuring that both flight attendants can stay connected without broadcasting their communication to the cockpit or other areas.

The other buttons listed, such as the PA button and CALL button, serve different purposes. The PA button is used for public address announcements to all passengers, while the CALL button typically initiates a general request for attention rather than a direct line of communication like the ATT button does. The SHIFT button is not relevant in this context, as it pertains to different system functions. Thus, the ATT button is the appropriate choice for direct communication between the flight attendants.
