Which list correctly identifies all lavatories on the 787-8?

• A. 1L, 2L, 2R, 3L, 3LC, 3RC, 3R
• B. 1L, 2L, 2R, 3L, 3RC, 3LC, 3R
• C. 1L, 2L, 2R, 3L, 3LC, 3RC, 3R
• D. 1L, 2L, 3L, 2R, 3LC, 3RC, 3R

Answer: (C)

Lavatories on the 787-8 are grouped by cabin zones and labeled by position relative to the aircraft’s centerline. The forward section has one lav located on the left side: 1L. In the middle section there are two lavatories: 2L and 2R. The rear cabin houses four lavatories: 3L at the far left, 3LC and 3RC in the center (left-center and right-center), and 3R at the far right. Taken together, this gives seven lavatories: 1L, 2L, 2R, 3L, 3LC, 3RC, 3R. There isn’t a forward right lavatory on this model, so any list that includes 1R would be incorrect. The other options either miss one of these rear lavatories or include an invalid one, so they don’t match all lavatories on the 787-8.
