The ends of the beam are placed under points on the lower wing roots. Although dual controls are provided, the pilots are arranged in tandem to give the first pilot the best possible view. On top of the lower centre-section is mounted the A.B.C. auxilary power unit, which is used for refuelling, bilging, charging the air bottles, and for generating electricity. The petrol and bilge pumps have a capacity of approximately 2,600 gallons per hour, and the air compressor will charge a 400 cu. in. bottle to a pressure of 200 lb./sq. in. in four minutes A beaching chassis complete with tail trolley is provided, and a jib for changing either of the six engines while the air craft is afloat is supported on the lower plane, with ties to the upper plane. Although positions are provided for two pilots, a three-axes automatic pilot is carried, so that '>n a long flight the aircraft controls may be abandoned by the crew for quite long periods. New Aero Engine Factory Announcement Important An important announcement regarding the Kingswood. Bristol, factory of Douglas Motors, Ltd., was made last week end. The works, which are well known by reason of the manu facture of Douglas motor cycies and light aero engines, have been purchased by the British Pacific Trust and, it is stated, production will \x started at an early date, on a very large scale. The Douglas factory is one of the largest and most com pletely equipped engine works in the country, and very little- time need be occupied in installing special machinery. A close working arrangement with General Aircraft, Ltd.. has been made and the new. inverted vee side-valve engine recently designed by this company will be one of the engines to be put into production In addition to engines, a wide range of aeroplane equipment will also be produced. Manufacture of the well-known Douglas products will be rontinued, including a light aero engine of the type which Mr. Kronfeld uses in the "Drone."
