Albatros L 57

The Albatros L 57 was an early monoplane designed by Albatros as an airliner project, intended to carry up to six passengers. It was never completed and as such never entered production. A distinctive feature was the top covering of the fuselage, which was swept up higher than on other similar aircraft of the era. The published specifications give a Mercedes D.IIIa engine, a length of 10.42 metres, a span of 14.20 metres, a wing area of 34.5 square metres, an empty weight of 1,036 kilograms and a flying weight of 1,850 kilograms, with a top speed at sea level of 149 kilometres per hour and a range of 540 kilometres on a full tank.
