The Cessna Citation VII is an upgraded version of the Citation III which was the first of the Model 650 series of Citation jets. This 650 series are mid-sized, high-performance business jets which is the second of six distinct “families” of jets marketed by Cessna Aircraft Company under its Cessna Citation brand.

Citation III

Designed as a high performance, mid size long range corporate jet, the all new Cessna Model 650 Citation III was to supplement the much smaller Citation I and II.

Development of this Citation began in 1978. As time evolved, so did the evolutions of its design until the III had little in common with the previous Citation models other than the name. It featured a swept supercritical wing optimized for high speed long range flight, new Garrett TFE731 turbofans, a Ttail, and a new fuselage.

Powered by a pair of Garrett TFE731-3B turbofan engines, The aircraft is flown by a crew of two, and with a typical corporate interior will seat six passengers, although in a high-density configuration, it can seat up to nine.

May 30 1979, the new jet made its first flight with a second prototype flying on May 2 1980. Certification was granted on April 30 1982 with first customer deliveries occurring the following year. The Citation III set two time to height records for its class in 1983 and a class speed record by flying from Gander to Le Bourget in 5hr 13min.

Citation IV first marked the production improvements to the Citation III but was soon cancelled. This model was announced in 1989 and was to feature better short field performance and longer range through greater fuel tankage. Instead, Cessna developed the Citation VI and VII. The Citation VI was offered as a lower cost development of the III with a different avionics package and a standard interior layout, though customized interiors was unavailable. First flight of the Citation VI took place in 1991 but only 39 were built when production was wound up in May 1995.

Meanwhile, The Citation VII which again was based on the III but intended to take a big step forward in performance, offered a number of improvements including more powerful engines for improved hot and high performance. The first prototype flew in February 1991 and was certificated in January 1992. The Citation VII remains in production as the only member of the Citation III/VI/VII currently available new build.
