The Citation Sovereign is Cessna’s version of what a business jet should be: comfortable, high-performing, and economical. The strongest feature of the Sovereign is its range: it has coast-to-coast capabilities, like large jets, but still retains the features that make midsize private jets so advantageous. It can take off in under 4000 feet, a feat still unmatched by other midsized jets, and can cruise at around .75 Mach (458 knots).

The Sovereign’s cabin is 24.5 feet long and can hold anywhere between eight and twelve 180 ° swivel seats. The cabin is large enough that passengers can stand up in the 5.7 foot-high cabin. The baggage space available in the Sovereign is the largest of comparable private jets. The Sovereign has 124 cubic feet of baggage space (about 1000 pounds), whereas the competing Hawker 400 XP has only 48 and the Challenger 300 has 51.

Even more storage space is available in the cabin, with a closet large enough to hold full-sized garment bags. The bathroom, too, is spacious – passengers can change their clothes in it with the assurance of complete privacy (due to the double sliding hard doors). A non-fluorescent lighting system was installed to increase passenger comfort and cut down on production costs. The lighting system now used has dimmable LEDs, which have a life of about 100,000 hours. The cabin and cockpit can be cooled before starting the engines by using APU.

It should be noted that Citations are not just popular with its passengers. Pilots love it, too. The Citation series was designed with the intent of simplifying flight as much as possible. Systems make sense and flight operations are uncomplicated, resulting in consistently safer, smoother flights.

For example, most of the Sovereign’s start up functions are automatic. If there is a malfunction while the engine is starting it is automatically shuts down. The stall control technology is so sophisticated that pilots say that the Sovereign could right itself in the event of a stall without any pilot involvement.

Trailing link landing gears are used on the Sovereign for smooth taxiing and landings. All main landing gear have double wheels, designed to last more than 300 landings. The carbon-carbon brake system is phenomenal as well and is cited to last for more than 300 landings. A variable gearing mechanism was added as well, to constantly change flaps to their best angle for flight, usually between 15 ° and 25 ° , resulting in greatly reduced pitch change. The Citation Sovereign was the first of any business jet to use the variable gearing mechanism, once again setting it apart from competing private jets.

The one area where Cessna decided not to cut costs and simplify was probably the most vital portion of the airplane: the wing. The Sovereign moves on from the cheap, easy-to-produce straight wings that earlier models used in favor or a wing with a 16 degree leading edge sweep an a 12.7 degree sweep at the quarter cord. This wing design greatly improves airflow and lift capabilities, resulting in the Sovereign’s cruise speeds of .75 Mach.

If the Sovereign’s top speeds don’t impress, it’s not due to any shortfall of its engines. Cessna fitted the Sovereign out with Pratt & Whitney Canada PW306C turbofan engines, which provide 5,600 lbs of thrust each on takeoff. The engines were flat-rated to minimize noise. The Sovereign has two jet fuel pump systems, a standard engine-driven one and another DC-powered system for backup and use during startup procedures.

Safety was, of course, a top priority for Cessna when they designed the Sovereign. Everything from its simple flying procedures to its many standard emergency systems prevent accidents and make handling them a lot simpler. A seventy six foot oxygen system comes standard, with an additional seventy six foot system, if requested. The Sovereign is certified to the safety standards of both FAR part 25 and JAR 25.

For a jet that has only been on the market since 1994, the Sovereign has done incredibly well. Pilots and clients love its versatility, its range, its simple systems, and its comfort. After all, a private jet that can fly directly from California to Hawaii in four and a half hours without breaking the bank has to be well-liked.
