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, with only the Citation X being larger. The Sovereign is considered a transcontinental aircraft and is used primarily for corporate travel.

Design and development

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 Canada PW306C turbofan 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.^[1][2]

Avionics
The system’s centerpiece is a quartet of 8 x 10-inch (.20 x .25 m) LCD displays. For optimum situational awareness, two Primary Flight Displays (PFDs) depict aircraft attitude, altitude, airspeed, vertical speed and heading references at the pilot’s and copilot’s stations. These PFDs flank two centrally mounted displays – one serving as a Multi-Function Display (MFD), and the other as an Engine Indicating and Crew Alerting System (EICAS) panel. Radio tuning is also presented on the MFD displays, and is controlled by cursor control devices located in the center pedestal or through either FMS. Reversionary switching from either PFD to the central displays provides backup redundancy.
