When 787's are parked at Everette, I notice that the windows are covered by black cover. Correct me if I am wrong, but I guess they do this to keep the sunlight out and to keep it from bleaching the seats or interior etc
My question is, what does the operator do when the 787 is parked outside for a few days in the hot sun with no external power attached. Will the window dimmer still work without power? How will they keep the sun out in those cases without having to black cover the window's all over again.
Apologies if this topic has been covered.
