Another 787 feature are the electronically controlled window shades. Using the button below each window, a passenger can dim the shade partway to block a bright sun or turn it completely dark for a night flight. The cabin crew can adjust all shades remotely.
On the very back of the 787, just below the vertical stabilizer (or tail), is the auxiliary power unit, or APU. It powers the aircraft when the engines aren't running and is used to start the engines before flight.
