By the time of the pre-departure announcement, has the exit row been briefed?

The exit row has been briefed by the time of the pre-departure announcement because it is a critical safety protocol in aircraft operations. The briefing ensures that all passengers seated in exit rows are aware of their responsibilities in the event of an emergency. These passengers need to understand how to operate the exit doors and must confirm their willingness to assist in an evacuation.

The pre-departure announcement serves as a reinforcement of safety information, highlighting the procedures to follow. By this time, the flight crew has already communicated with these passengers individually or as a group to ensure they comprehend their roles and responsibilities. This crucial step is intended to enhance passenger safety and ensure a prompt and orderly exit in case of an emergency.

Other options suggest a lack of briefing or conditional briefing, which do not align with standard safety protocols that prioritize passenger awareness and preparedness before the flight begins. It is an essential part of the safety demonstration that enhances overall readiness for all on board.
