Haus Vaterland metres deep, panoramas, and lighting effects, and served appropriate food; it was an early example of modern theme dining or experiential gastronomy. While the main shows took place in the ballroom, each theme restaurant also had musicians of the appropriate origins on staff to complete the dining experience, including at least six dance bands. A central kitchen occupied the entire top floor, connected to the different dining establishments by pneumatic tubes, through which orders came up, and dumbwaiters, by means of which food was sent down and dirty dishes sent back up; conveyor belts at kitchen level transferred the dishes
Lift-to-drag ratio edged wings, and formula_3 the zero-lift drag coefficient. Most importantly, the maximum lift-to-drag ratio is independent of the weight of the aircraft, the area of the wing, or the wing loading. It can be shown that two main drivers of maximum lift-to-drag ratio for a fixed wing aircraft are wingspan and total wetted area. One method for estimating the zero-lift drag coefficient of an aircraft is the equivalent skin-friction method. For a well designed aircraft, zero-lift drag (or parasite drag) is mostly made up of skin friction drag plus a small percentage of pressure drag caused by flow separation. The
