Cabin ceiling projections of stars, clouds and colors; huge curved flat-panel in-flight entertainment (IFE) displays; advanced lighting systems; massive translucent cabin monuments displaying current flight status and moving maps. These are just some of the concepts being worked on by engineers in Boeing’s Commercial Airplanes Product Development group. “Airlines are telling us that they want to have interiors that have a wow factor, and set their cabin apart from [those of] their competitors,” says Mark Ellis, senior manager, Payloads Product Development.
