Nord NC.850
1940s French light aircraft
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.[1][2]
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.[2][3] 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.[4]
The competition was won by the SIPA S.90, but SALS nevertheless also ordered 100 examples of this, the runner-up design.[2] These production examples, designated NC.853, differed from the prototypes in having twin tails, the fins mounted on the ends of the horizontal stabiliser.[2] Only 27 of the order had been completed, however, when Aérocentre was liquidated and its assets bought by Nord.[2] The new owners continued production, with their machines identified with designation NC.853S.
In March 1951, Nord flew a heavily modified version of the design for use as an observation aircraft by the French Army.[2] Known as the NC.856 Norvigie, this featured a more powerful engine and a lengthened and more extensively glazed cockpit.[2] The army ordered 112 examples which were mostly flown in the artillery spotting role,[5] and while a civil version was also offered, orders were not forthcoming[6] and only two were built.[5] The sole example of a floatplane version was presented as a gift to King Norodom Sihanouk of Cambodia.[6]
