Development

The $14.9 million Citation Latitude was announced by Cessna at the annual NBAA convention in October 2011, between the $12.6 million Citation XLS+ and the $17.5 million Citation Sovereign. The prototype first flew on 18 February 2014 in Wichita, Kansas. Cessna announced on June 5, 2015, that it had achieved FAA certification for the type. On August 27, 2015, Cessna announced the first deliveries had begun. In 2023, its equipped price was $19.775M.

Design

It keeps the Citation Sovereign wing, twin Pratt & Whitney Canada PW306D turbofans and cruciform tail. Its newly-designed all-metal stand-up circular fuselage has a flat floor and seats nine.

Typical missions are 2.0–2.7 hours and with 400 kn (740 km/h) block speeds and most operators can fly 5–6 hours at Mach 0.72–0.76 for a 2,000–2,400 nmi range, with short takeoff requirements and good hot and high performance. A first hour fuel burn of 2,000–2,500 lb (910–1,130 kg) followed by 1,600–1,900 lb (730–860 kg) the second hour and fuel burn can reach 3,300 lb (1,500 kg) for a 2-hour trip with favorable conditions. It lists for $17.5–18 million typically equipped, the same as the Embraer Legacy 450 with a similar flat floor cabin for club four plus two chairs and over 200 miles more range, 25–30 kn (46–56 km/h) higher cruise and fly-by-wire controls. Embraer is firm on list price while Textron discounts the Latitude by up to 20% for $13.5–14 million to sell three times as many aircraft.

Deliveries to customers began in the third quarter of 2015 and sixteen had been handed over by the end of the year. By May 2018, almost three years since introduction, 124 had been delivered and had logged 80,000 flight hours.

In June 2018, of 129 delivered, 104 were in the US, three in Mexico, two each are based in China, France and Turkey, and there was one each in Chile, Paraguay, the Philippines, Poland, Scotland and Switzerland. It is used by medium-size corporations, typically flying 200–300 hours per year, and large fleet operators, the largest being NetJets which booked 25 firm orders and 125 options in 2012 and received 44 aircraft for its U.S. operations and 10 for Europe by June 2018, flying theirs over 1,000 hours per year. By mid-September, the 136 delivered had logged 115,000 flight hours, and Textron claimed it was outselling the competition by four to one.
