Where is the lavatory located for the 70 PAX aircraft?

• A. One lavatory located in the aft cabin
• B. One lavatory located in the forward cabin
• C. Two lavatories located in the mid cabin
• D. No lavatories are installed

Answer: (A)

In a 70 PAX aircraft, the lavatory arrangement is designed to balance passenger access, weight, and practical plumbing. The standard setup is a single lavatory located in the aft cabin. This positioning keeps the front area open for the galley and cockpit and minimizes the length of waste plumbing and supporting systems, helping to keep weight down and maintenance straightforward. A lavatory in the forward or mid cabin would disrupt passenger flow and cabin layout, and having two lavatories adds unnecessary weight on a 70-seat airframe. No lavatories would not meet typical passenger service requirements. So, one lavatory in the aft cabin is the most typical and practical configuration.
