The Cessna Citation X is a high-performing, fast super-midsize jet that has a maximum speed of 0.92 Mach. The jet was designed with fuel efficiency in mind, featuring the Rolls-Royce AE3007C1 turbofan engine, which delivers 8,600 pounds of thrust and has the lowest specific fuel consumption for a private jet in its class. The Citation X can fly at FL510 with an average fuel burn of 2,000 pounds per hour, and its zero fuel weight is 24,400 pounds. At a cruising altitude of FL410, the jet will burn 2,457 pounds of fuel per hour, while at FL510, fuel burn decreases to 1,380 pounds per hour. The cost of flying the Citation X for 400 hours a year, including fuel, maintenance, landing, and handling, is approximately $1.66 million.

The Cessna Citation X has a fuel flow of 336 gallons per hour
The Cessna Citation X is a high-performing, fast super-midsize jet that has a maximum speed of 0.92 Mach. It is one of the fastest business jets in the world and is a favourite among travellers for its cabin comfort. The jet was introduced in 1990 and has since undergone several improvements to its design and speed.
The Citation X has a fuel flow of 336 gallons per hour. This fuel flow rate allows the jet to reach a cruise speed of 0.90 Mach. To achieve this speed, aerospace engineers spent months analysing the jet's aerodynamic structure with computational fluid dynamics computer technology. The proposed design was then tested in a wind tunnel and analysed by computer programs to locate areas of high drag.
The jet's frame was then adjusted with precision instruments, sometimes to as little as 1/100,000th of an inch. These modifications continued for months until the desired speed was achieved. While Cessna spent a lot of effort fine-tuning the jet's aerodynamic structure, the Citation X's fuel efficiency may not have been a primary concern.
The jet's engines have the highest thrust-to-weight ratio available and the lowest specific fuel consumption for a private jet in its class. The Rolls-Royce AE3007 C1 turbofan engine delivers 8,600 pounds of thrust and was fine-tuned to run at a lower temperature, allowing the jet to run its engines for longer. The fuel burn rate can vary depending on the altitude and speed of the aircraft. For example, at a cruising altitude of FL410, the jet will burn 367 gallons of fuel per hour.

It can fly at FL510 for better comfort and speed, burning 2000 pounds per hour
The Cessna Citation X is a high-performing, fast super-midsize jet that can fly at FL510 for improved comfort and speed, burning 2000 pounds per hour. This altitude provides ideal flight conditions for passengers, with a maximum speed of 0.92 Mach. The jet can reach FL510 in steps, but it is a challenging process. To reach FL470, the jet must burn 2100 pounds, and to reach FL490, it needs to burn an additional 4000 pounds to get to 30,000 pounds.
Citation X pilots carefully calculate the required fuel for each trip to optimise fuel efficiency and performance. The jet can take on a maximum of 12,931 pounds of fuel while still accommodating five passengers with their baggage. The aircraft's basic operating weight, which includes two crew members and catering services, is 22,100 pounds. The zero fuel weight is 24,400 pounds, and with a full payload, the jet can carry 11,700 pounds of fuel.
The Citation X is known for its speed and performance, with a maximum operating Mach (MMO) of 0.92 or 547 KTAS. The jet's engines, designed by Rolls-Royce, deliver 8600 pounds of thrust and have the highest thrust-to-weight ratio in their class, along with the lowest specific fuel consumption. The Full Authority Digital Engine Controls (FADEC) system manages the engine's performance to prevent damage from excessive speed.
The cost of operating the Citation X is relatively inexpensive for a private jet, considering its speed and comfort. The average price for a used jet is around $6 million, depending on its age and condition. Operating costs for 400 hours of flight time per year can reach approximately $1.66 million, including fuel, maintenance, landing fees, and other expenses.

At FL430, it burns 2000 pounds per hour
The Cessna Citation X is a high-performing, fast super-midsize jet that has a maximum speed of 0.92 Mach. It can fly at a maximum altitude of FL510 in steps. The jet has a zero fuel weight of 24,400 pounds, which means that with maximum payload, it can carry 11,700 pounds of fuel. The aircraft's basic operating weight, which includes two crew members and catering, is 22,100 pounds, resulting in a maximum payload of 2,300 pounds.
Citation X pilots never fill up with fuel they don’t need. Each trip is calculated for precise flight requirements and reserves with a small fudge factor. This way, they can get up to altitude faster and burn less fuel.
At FL430, the Citation X will burn 2000 pounds of fuel per hour. To reach this altitude, it can take the jet 26 minutes, burning 1,332 pounds (199 gallons) of fuel. During this time, it will also travel 174 nautical miles laterally.
At a higher altitude of FL490, the jet burns less fuel, at 1400 pounds per hour or 210 gallons per hour. At its maximum altitude of FL510, the fuel burn is even lower, at 1,380 pph (about 205 gph).

At FL490, it burns 1400 pounds per hour
The Cessna Citation X is a high-performing, fast super-midsize jet that has a maximum speed of 0.92 Mach. It is one of the fastest business jets in its class and is a favourite among travellers for its cabin comfort. It can fly up to FL510 in steps, but this is typically reserved for longer-range flights.
Citation X pilots never fill up with fuel they don't need. Each trip is calculated for precise flight requirements and reserves, allowing the jet to get up to altitude faster and burn less fuel. At FL430, the jet will burn 2000 pounds of fuel per hour.
At FL490, the Cessna Citation X burns 1400 pounds of fuel per hour, or 210 gallons per hour. This is a significant decrease in fuel burn from lower altitudes. For example, at a typical cruising altitude of FL410, the jet will burn 2457 pounds per hour.
The Citation X has a zero fuel weight of 24,400 pounds, which means that with maximum payload, there can be 11,700 pounds of fuel on board. The aircraft's basic operating weight, including two crew members and catering, is 22,100 pounds, resulting in a maximum payload of 2300 pounds. The jet can take a maximum of 12,931 pounds of fuel, leaving 1069 pounds for payload.
