Final answer:
Wheelchair accessible toilets on the Boeing 787-9 Dreamliner are usually located in the middle or rear of the plane, with exact placement varying by airline configuration. Passengers with special needs should inquire with the airline beforehand for details and assistance.
Step-by-step explanation:
The location of wheelchair accessible toilets on a Boeing 787-9 (B789) Dreamliner can vary depending on the airline and the specific configuration of the aircraft. However, generally, larger commercial airplanes like the B789 are required to have accessible lavatories for passengers with reduced mobility. These restrooms accommodate wheelchairs and are designed to provide the necessary space and assistance features such as grab bars and call buttons.
In most B789 configurations, wheelchair-accessible toilets are commonly located near the middle or rear of the plane, where there is enough space to allow for a larger restroom. It's always a good idea for passengers who need these facilities to verify the exact location with the airline before their flight, as they can assist with specific seating arrangements to make the journey more comfortable.
Passenger service personnel on board the B789 are also available to assist any passengers with disabilities, helping them to locate and use the wheelchair-accessible facilities with safety and ease.
