What does the term "Deplane" refer to?

The term "Deplane" specifically refers to the process of passengers exiting or leaving the aircraft after their flight has concluded. It is commonly used in the airline industry to describe the action that takes place once a plane has reached its destination and is ready for passengers to disembark. This term is important for flight attendants and ground staff to understand as it relates to safety protocols and the efficient management of passenger flow after landing. It signifies the end of one phase of travel and the beginning of another for passengers.

In contrast, the other options provided describe different actions or processes related to air travel, such as boarding the aircraft, conducting safety checks, or transferring to connecting flights, which do not align with the specific action of deplaning.
