The Cessna Citation Sovereign (Cessna Model 680 Sovereign) is an American mid-size business jet developed by Cessna. It is currently the second largest member of the Citation product line in terms of take-off weight, with only the Citation X having roughly 6000 lbs greater take-off weight. The Sovereign is considered a transcontinental aircraft with the capability to fly Los Angeles to Hawaii greater than 98% of the time, while complying with ETOPS requirements, and is used primarily for corporate travel.
In the late 1990s, Cessna saw the need for a high-performance jet midway between the Excel/XLS size and the Citation X. The result was the Model 680 Citation Sovereign, powered by two Pratt & Whitney CanadaPW306Cturbofan engines with FADEC controls. It uses the Honeywell Primus Epic glass cockpit avionics suite, coupled with dual Honeywell FMZ2000 FMS units. Its claim to fame is that it can take off and land in short distances, thanks to a moderately swept high aspect ratio wing, and (when light) 92 knot Vref speed. It was first unveiled to the public in 1998 at the NBAA exhibition in Las Vegas, Nevada. The Sovereign seats eight passengers in a typical cabin configuration, with a maximum high-density capacity of 12, in addition to the crew of two.
First flight of the Sovereign took place in February, 2002, with FAA certification awarded in June, 2004. Customer deliveries began later that year. EASA certification came in June 2014.
