The Nieuport-Delage NiD 640 was a French four-seat cabin monoplane that first flew in 1927, designed for civil aviation and private ownership. Powered by a single engine, it achieved a respectable 205 kilometers per hour maximum speed while maintaining practical dimensions of 9.4 meters length and 15.4 meters wingspan. The enclosed cabin provided weather protection and basic comfort for small groups, while performance remained adequate for regional business flying. This aircraft represented the practical civil designs emerging during the late 1920s for middle-market private operations.
