Aviation Boeing working on a self-cleaning airplane bathroom By Robert Silk / March 07, 2016 Share 1 Along with the self-cleaning technology, the prototype lavatory is touchless. -- Boeing has submitted a patent application for a self-cleaning airplane bathroom.The lavatory, a prototype of which has been developed by Boeing engineers and designers, would use ultraviolet (UV) light to kill what Boeing says are 99.99% of germs."In the prototype, we position the lights throughout the lavatory so that it floods the touch surfaces like the toilet seat, sink and countertops with the UV light once a person exits the lavatory. This sanitizing even helps eliminate odors," explained Jeanne Yu, Boeing Commercial Airplanes' director of environmental performance.Boeing says the cleaning system can disinfect all surfaces in the bathroom after every use in three seconds. Along with the self-cleaning technology, the prototype lavatory is touchless, incorporating a hands-free faucet, soap dispenser, trash flap, hand dryer and toilet lid. In addition, the lid would lift and lower automatically between bathroom uses so that all surfaces are cleaned. The lavatory has a way to go before it reaches market. Boeing said the cleaning system will require more study before it can be offered to airlines. Carriers would then have to retrofit planes, or purchase new aircraft, in order to have the self-cleaning lavatories on their flights.
