The SNCAC NC.510 was a twin-engine French reconnaissance, army co-operation or advanced training aircraft, built in the late 1930s. Three were built and refined but production orders were not forthcoming.
The Société Nationale de Constructions Aéronautique du Centre (SNCAC) was formed via 1936 legislation in February 1937 as a nationalised merging of the Farman and Hanriot companies, in whose design offices several SNCAC types began. Thus the NC.510 was often referred to as the Hanriot 510 or Hanriot NC.510.
The NC.510 was designed for army co-operation work and as an advanced training aircraft. It was a twin-engined mid-wing monoplane. Between the engines and fuselage the wing was rectangular in plan and externally braced; the outboard panels were tapered cantilevers. The wings were built around two metal spars and the centre section was all metal, with metal ribs and skinning. Outboard their construction was mixed, with wooden ribs and a mixture of metal and fabric covering. Split flaps were fitted.
The SNCAC NC.860 (also known as the Aérocentre NC.860) was a French twin-engined development of the NC.853 light aircraft.
The NC.860 was developed from the earlier NC.853 single-engined high-wing monoplane, major changes included a four-seat cabin and the fitting of two 105 hp (78 kW) Walter Minor 4-III engines on a re-designed wing. With the engines mounted on the high-wing the wing span was increased and the NC.860 had a tricycle landing gear.
The NC.860, registered F-WFKJ, first flew 28 March 1949.

The Nord NC.850 (originally produced as the Aérocentre NC.850) was a light aircraft developed in France in the late 1940s for use by French aeroclubs but which also saw military use as an airborne observation post.
The NC.850 series was developed from the Aérocentre NC.840 in response to a competition sponsored by the French government under the auspices of the SALS movement to find a domestically-produced machine for club use.Aérocentre's entry was an ungainly high-wing, strut-braced monoplane with a fully enclosed cabin and fixed, tailwheel undercarriage. The fuselage construction was tubular, and the wings had a metal structure, the entire aircraft being skinned in fabric.
The competition was won by the SIPA S.90, but SALS nevertheless also ordered 100 examples of this, the runner-up design. These production examples, designated NC.853, differed from the prototypes in having twin tails, the fins mounted on the ends of the horizontal stabiliser. Only 27 of the order had been completed, however, when Aérocentre was liquidated and its assets bought by Nord. The new owners continued production, with their machines identified with designation NC.853S.
SNCAC, the Société Nationale de Constructions Aéronautiques du Centre, sometimes known as Aérocentre, was a French aircraft manufacturer created by the nationalisation of the Farman Aviation Works and Hanriot firms in 1936. It was liquidated after World War II, with assets distributed between other nationalised firms SNCAN, SNCASO, and SNECMA in 1949.
