I have done a search and not come up with anything. Does anyone know what the various colors of indicator lights mean on the Airbus aircraft, there is one "bank" on the aisle ceiling just behind the cockpit door and another about mid-way back again on the aisle ceiling. I think there are 4 colors. I think that I figured out that green on represents being above 10,000 feet, but not sure. Can anyone confirm this and know the meaning of the others?
