According to the division of duties, who is responsible for checking the lavatory prior to surface movement on the CRJ 700?

The responsibility for checking the lavatory prior to surface movement on the CRJ 700 falls to the aft flight attendant. This is an important safety procedure, as it ensures that the lavatory is secure and that there are no issues that could arise during taxi, takeoff, or landing. The aft flight attendant has specific duties during the flight and is positioned towards the rear of the aircraft, making them the best choice for overseeing this area.

The forward flight attendant, cabin supervisor, and any flight attendant do not have this specific responsibility assigned to them in the context of preparing the aircraft for movement. The division of labor is crucial in flight operations to maintain efficiency and ensure passenger safety, with each crew member having defined roles that contribute to the overall functioning of the cabin crew during critical phases of flight.
