True or False: The lavatory waste bin on the ERJ 175 must not have a liner installed.

The statement is true because the lavatory waste bin on the ERJ 175 is designed to operate without a liner installed. This design is essential for the proper functioning of the waste management system, as the absence of a liner prevents potential blockages and ensures that waste can be handled appropriately. Inserting a liner could interfere with the waste removal mechanisms, leading to operational issues during the flight. Understanding this requirement is critical for maintaining aircraft cleanliness and ensuring the lavatory's operational efficiency during flights.
