MARCH 15, 1928 THE BREDA A.7 MONOPLANE : The machine can be converted into a seaplane by replacing the wheel undercarriage with twin float gear. construction that a very strong and ' rigid structure is obtained, especially in the matter of torsional stresses. The A.7 wing is capable of withstanding any form of stunting. A portion of the trailing edge of the plane is cut away at the centre, above the pilot's cockpit, in order to provide an unobstructed view upwards. The ailerons are of fairly large proportions, extending for nearly half the length of each wing, and thus render the machine very manoeuvrable. Lateral control is further facilitated by the provision of small auxiliary balancing surfaces mounted on the ailerons. The rudder and elevators are also balanced. The fuselage of the A.7, which is of rectangular cross- Section, is constructed entirely of steel, also from pressed sheet, riveted together, being built up of longitudinal and numerous transverse members. The pilot's cockpit, which is very comfortable, is situated below the trailing edge of the 'plane, and immediately behind is the observer's cockpit. Both are provided with controls—the joystick in the observer's cockpit being removable—while the pilot's dash- board, containing a full range of instruments, is placed so as to give easy reading of the latter. In the pilot's cockpit, also, is a self-starter for the engine, while a small wheel close at hand enables the incidence of the tail plane to be adjusted during flight. The 500 h.p. Isotta Fraschini engine and its steel mounting forms a separate and detachable unit, being secured by four bolts and thus providing for quick and easy changing of the power plant. The whole engine is completely enclosed in a neat metal housing, the radiator being slung beneath the fuselage. Sufficient fuel is carried for a flight of seven hours.The landing gear is another distinctive feature of the Breda A.7, being of the non-axle type constructed of rivetedsheet steel. Each wheel is carried by two enclosed Vs. the shock absorbers, which are particularly soft in action, beingcontained within the outer Vs. The A.7 is easily converted from a land machine into aseaplane by fitting two floats in place of the wheels. The first machine of this type was recently tested at the Bredafactory at Mestre (Venice), and gave good results both as a land-plane and seaplane.
