The Citation X+ is a high-performance business jet built for speed and long-distance travel

The Cessna Citation X+ is a twin-engine jet aircraft designed and manufactured by Textron Aviation, a division of Textron Inc. It is one of the fastest business jets in production, with a maximum speed of Mach 0.935 (roughly 717 miles per hour). The aircraft seats up to 12 passengers depending on configuration, though most operators configure it for 8 to 10 passengers to maximize comfort on longer flights.

The Citation X+ entered service in 1996 as the Citation X, and Textron released an upgraded version called the Citation X+ in 2007. The newer variant includes improved engines, avionics, and interior options. Both versions remain in active service with corporate flight departments, charter operators, and private owners.

Key Takeaways

  • The Citation X+ cruises at speeds up to Mach 0.935, making it one of the fastest business jets available for charter or private ownership.
  • The aircraft is powered by two Rolls-Royce AE 3007C2 turbofan engines and has a range of approximately 3,290 nautical miles, allowing transcontinental flights without refueling.
  • Operating costs for the Citation X+ are higher than smaller jets because of fuel consumption and engine maintenance, typically ranging from $4,000 to $6,000 per flight hour depending on market conditions and operator.
  • The cockpit requires two pilots and modern avionics training; the aircraft is equipped with the Garmin G5000 integrated flight deck on newer examples.
  • Charter operators and fractional ownership programs offer access to the Citation X+ without the full cost of ownership, though availability varies by region and season.

Engine specifications and fuel capacity

The Citation X+ is powered by two Rolls-Royce AE 3007C2 turbofan engines, each producing 5,511 pounds of thrust. These engines are the primary reason the aircraft achieves its high cruise speed. The engines require regular maintenance inspections at intervals specified by Rolls-Royce and Textron, which adds to the operating cost.

The aircraft carries a maximum fuel capacity of 6,502 pounds (approximately 975 gallons). At typical cruise speed and altitude, the Citation X+ burns between 260 and 290 gallons per hour, depending on weight, weather, and flight profile. This fuel consumption rate means a full tank supports roughly 3.5 hours of cruise flight, though actual range depends on payload, reserves, and routing.

Range, payload, and typical mission profiles

The Citation X+ has a maximum range of approximately 3,290 nautical miles with four passengers and reserves. This distance covers most transcontinental routes in North America — for example, New York to Los Angeles or Miami to Seattle — without an intermediate stop. Longer international routes typically require a fuel stop, usually in the Caribbean or Central America.

Maximum payload (passengers plus cargo) is around 4,750 pounds. In practice, a fully loaded aircraft with 10 passengers and baggage will have reduced range compared to the maximum-range configuration. Operators and charter brokers calculate actual range for each flight based on passenger count, cargo weight, weather routing, and fuel reserves required by regulation.

Cockpit requirements and pilot training

The Citation X+ requires a crew of two pilots and is certified for single-pilot operation only under specific conditions and with additional training. Most operators and all charter companies require two pilots for safety and regulatory reasons. Pilots must hold an Airline Transport Pilot (ATP) certificate or Commercial Pilot certificate with appropriate ratings, and they must complete type-rating training specific to the Citation X+ through an approved training center.

The aircraft is equipped with the Garmin G5000 integrated flight deck on newer examples, which combines navigation, autopilot, and engine monitoring into a unified system. Pilots transitioning from older glass cockpits or steam gauges typically require 20 to 40 hours of ground and simulator training before flying the aircraft. Recurrent training and proficiency checks are required annually or every two years depending on the operator's program.

Ownership costs and operating expenses

The direct operating cost (DOC) for the Citation X+ typically ranges from $4,000 to $6,000 per flight hour, though this varies based on fuel prices, maintenance reserves, crew salaries, and hangar location. Fuel alone accounts for roughly 40 to 50 percent of direct operating costs. Engine overhaul reserves, scheduled maintenance, and unscheduled repairs add another 30 to 40 percent. Crew, insurance, and hangar rent are separate fixed costs that do not scale with flight hours.

A rough estimate for annual fixed costs (assuming 200 to 400 flight hours per year) ranges from $800,000 to $1.2 million, including crew, insurance, hangar, and maintenance reserves. These figures vary significantly by location, maintenance facility, and the age and condition of the specific aircraft. Older examples may have higher maintenance costs due to component wear and parts availability.

Charter and fractional ownership options

Charter operators offer access to the Citation X+ without ownership. Charter rates typically range from $5,500 to $8,000 per flight hour, depending on market conditions, advance booking, and routing. Charter is most economical for operators who fly fewer than 200 hours per year or who need flexibility without the commitment of ownership.

Fractional ownership programs, such as NetJets and Flexjet, allow multiple owners to share one aircraft. A fractional share typically represents 1/16th to 1/8th of an aircraft and includes a may provide number of flight hours per year (usually 50 to 100 hours). Fractional programs handle all maintenance, crew, and insurance, and owners pay a monthly management fee plus an hourly flight cost. This option suits operators who want more control than charter but less responsibility than full ownership.

Maintenance and inspection requirements

The Citation X+ follows a maintenance program based on flight hours, calendar days, and cycles (takeoffs and landings). Scheduled inspections include 25-hour, 100-hour, and annual checks, with major overhauls required at intervals set by Textron and the FAA. Engine overhauls are typically due every 5,000 to 6,000 flight hours, and overhaul costs for a Rolls-Royce AE 3007C2 engine range from $1.5 million to $2.5 million per engine depending on condition and the repair facility.

Unscheduled maintenance and repairs are unpredictable but common on any aircraft. Owners typically set aside 10 to 15 percent of annual operating costs as a reserve for unexpected repairs. Maintenance must be performed by FAA-certified mechanics at authorized service centers, which limits where the aircraft can be serviced and may require repositioning the aircraft for major work.

Frequently Asked Questions

How fast does the Citation X+ actually fly?

The maximum cruise speed is Mach 0.935, which equals approximately 717 miles per hour at typical cruise altitude. Actual cruise speed on a given flight depends on weather, air traffic control routing, and fuel efficiency targets. Most operators cruise at Mach 0.80 to 0.90 to balance speed with fuel burn.

Can the Citation X+ fly internationally?

Yes. The aircraft is certified for international operations and equipped with long-range navigation systems. Most flights to Europe or the Caribbean require a fuel stop, typically in Newfoundland or the Azores. The aircraft is not pressurized for flight over the North Pole, so polar routes are not available.

What is the difference between the Citation X and Citation X+?

The Citation X+ (introduced in 2007) has more powerful engines, improved avionics, and a redesigned interior compared to the original Citation X (1996). The X+ is faster and has slightly better range. Both versions are still in service, but the X+ is preferred for new charters and ownership.

How many passengers can the Citation X+ carry?

The aircraft is certified for up to 12 passengers, but most operators configure it for 8 to 10 to maximize comfort and reduce weight. Fewer passengers allow longer range and faster climb performance. Charter brokers will confirm the exact seating for your flight.

Is the Citation X+ cheaper to operate than larger jets?

The Citation X+ has lower fuel burn and smaller crew requirements than large cabin jets like the Gulfstream G650, but higher operating costs than smaller jets like the Citation X or Learjet 75. It is most economical for operators who need speed and transcontinental range without the size and cost of ultra-large cabin aircraft.
