Final Answer:
The Airbus A320 Classic typically has 3 lavatories, while the A320M generally has 2 lavatories.
Step-by-step explanation:
The number of lavatories, or bathrooms, on an aircraft can vary based on its configuration and model. The Airbus A320 Classic variant typically includes three lavatories. These lavatories are strategically positioned throughout the cabin to cater to the passengers' needs and are usually located at different sections of the aircraft for easy accessibility.
On the other hand, the Airbus A320M, a modified version, commonly features two lavatories. The reduction in lavatories might be due to a modified interior layout, adjustments in seating capacity, or other design changes made by airlines or manufacturers.
The allocation of lavatories in an aircraft is part of the cabin layout, where factors such as passenger capacity, comfort, and airline preferences are taken into account. These lavatories are essential for passenger convenience during flights, and the number can vary based on the specific model and configurations chosen by airlines.
