Final answer:
The A321S aircraft does not have 'lavs' directly, but it includes lavatories for passenger use. The number of lavatories can vary depending on the airline and aircraft configuration.
Step-by-step explanation:
The A321S, which is an aircraft model, does not have 'lavs' directly. However, lavatories or toilets are included in the aircraft for passenger use. The exact number of lavatories in an A321S may vary depending on the specific airline and configuration of the aircraft. Typically, an A321S will have multiple lavatories strategically placed throughout the cabin to accommodate the passengers' needs.
For example, in a typical layout, an A321S might have lavatories located at the front and back of the aircraft, as well as in the middle section. The exact number can vary, but it is common to have at least one lavatory at the front and back, and additional ones in between to ensure easy access for passengers.
It's important to note that the number and placement of lavatories can be modified by airlines based on their specific needs and requirements, so it's a good idea to consult the specific airline or aircraft specifications for the most accurate information.
