Design and development

The C.92, first flown in 1925, was a close but more powerful relative of the C.91 from 1924. It was a two bay biplane with pairs of upright, parallel interplane struts between its wings, which were rectangular plan out to angled tips. The upper wing was supported centrally on four short

was neatly cowled in the nose, with twin cylindrical Lamblin radiators externally mounted below it. Behind the engine the fuselage was flat-sided with a rectangular section, starting with a baggage space. Above it, the pilot and navigator sat side by side in open cockpits. The passenger cabin behind the baggage space accommodated four, each with their own windows and electric heating. Entry was via a port side door. The tail of the C.92 was conventional, with a
