What You'll Learn
The Cessna Citation II's fuel capacity is 742 US gallons
The fuel capacity and performance improvements in the Cessna Citation II were achieved through several design changes. These included stretching the fuselage by 1.14 metres (3 feet 9 inches), increasing the wingspan by 5.1 feet (1.6 metres), and installing more powerful engines. The cabin interior was also redesigned to increase headroom by 5 inches (13 centimetres).
The Cessna Citation II's fuel capacity provides a significant advantage over its predecessor, the Citation II/SP, which had a shorter range of just 1,159 nautical miles. The increased fuel capacity also contributes to the aircraft's higher cruise speed.
It is worth noting that the fuel burn rate for the Cessna Citation II can vary depending on various factors, such as the specific model and flight conditions. On average, Cessna Citations burn 175 gallons of fuel per hour, but this can differ based on the aircraft's class and other variables.
Additionally, modifications to the engines and fuel efficiency enhancements have been developed by companies such as Clifford Development and Sierra Industries, offering further improvements in range, cruise speed, and fuel efficiency for the Cessna Citation II.

The average Cessna burns 175 gallons of fuel per hour
The Cessna Citation is a family of business jets that was first introduced in 1972. Since then, Cessna has released 27 aircraft models with varying specifications. The average Cessna burns 175 gallons of fuel per hour, but this number can vary depending on the model. For example, the Citation XLS+ burns 211 gallons of fuel per hour, while the Citation II has a fuel capacity of 742 gallons.
The fuel efficiency of Cessna Citations has improved over time. The Citation Bravo, which was produced between 1995 and 2006, offers 15% more thrust at takeoff and 23% more at altitude, resulting in improved fuel efficiency. Modifications to the Citation II by Clifford Development in Ohio have resulted in a 20% improvement in fuel efficiency, while a similar modification by Sierra Industries in Texas has led to a 29% increase in range.
The cost of operating a Cessna Citation jet is influenced by factors such as the aircraft's condition, configuration, and operating environment. The price of fuel is a significant factor, with fuel prices spiking as high as $8 to $13 per gallon. At $5 per gallon, the average Cessna burning 175 gallons per hour would incur a fuel cost of $875 per hour.
When considering the purchase of a Cessna Citation or any private jet, it is essential to understand the costs beyond the initial purchase price. These costs can vary depending on the model and its specifications, such as turboprop or jet engines. Additionally, the size of the jet will impact crew requirements and associated expenses.

The Citation XLS+ burns 211 gallons of fuel per hour
The Cessna Citation is a family of business jets that was first introduced in 1972 with the 500 Citation l. Since then, Cessna has released 27 aircraft models in the Citation l, Citation lll, and Latitude lines. The Cessna Citation II, for example, stretches the Citation I fuselage by 1.14m, increasing seating capacity to ten (two pilots and eight passengers) and gross weight to 13,300 lb. The fuel capacity of the Cessna Citation II is 742 US gallons, and it cruises at a speed of 385 knots with a range of 1,159 nautical miles.
The fuel capacity and consumption of Cessna Citations vary across different models. For instance, the Citation Bravo, which was first delivered in February 1997, burns 1,100 lb (500 kg) of fuel in the first hour, 750-830 lb (340-380 kg) in the second hour, and 637 lb (289 kg) in the third hour. On the other hand, the Citation XLS+, which sits in the average price range for the Cessna Citation family, burns 211 gallons of fuel per hour.
The cost of operating a Cessna Citation depends on various factors, including the aircraft's condition, configuration, and operating environment. The average fuel burn per hour (GPH) also depends on the class of the aircraft. For example, large jets burn an average of 370 GPH, resulting in high fuel costs. Cessna Citations, on average, burn 175 gallons of fuel per hour, with fuel prices ranging from $5 to $13 per gallon.
When considering the purchase of a Cessna Citation or any private jet, it is essential to understand the costs beyond the initial purchase price. These costs can vary significantly depending on the model and specifications chosen. Therefore, it is recommended to consult a professional aviation consultant for detailed information on the financial aspects of owning and operating a private jet.

The Citation Bravo burns 1,100 lb of fuel in the first hour
The Cessna Citation is a family of business jets that debuted in 1972. The cost of owning one of these jets varies depending on the model and its specifications. For example, the Citation XLS+ burns 211 gallons of fuel per hour, while the average Cessna Citation burns 175 gallons of fuel per hour.
The Citation Bravo, which first flew in 1995, is a specific model within the Cessna Citation family. It features new P&WC PW530A turbofans, modern Honeywell Primus EFIS avionics, a revised interior, and a trailing-link main undercarriage. Its efficient PW530A engines generate 15% more thrust at takeoff and 23% more at altitude.
In the first hour of flight, the Citation Bravo burns 1,100 lb (500 kg) of fuel. This is significantly more fuel than the average Cessna Citation, which burns 175 gallons of fuel per hour. However, it's important to note that the Bravo's fuel consumption decreases in the second and third hours of flight.
In the second hour, the fuel burn drops to 750-830 lb (340-380 kg) while cruising at 360-365 knots (667-676 km/h) at FL410-430. In the third hour, the fuel burn is further reduced to 637 lb (289 kg) while cruising at 350 knots (650 km/h) at FL450. This decrease in fuel consumption over time is a notable feature of the Citation Bravo's performance.
The fuel capacity and efficiency of the Cessna Citation models have improved over time. For example, the Citation II, introduced in 1976, had a fuel capacity of 742 US gallons (2,810 L), which was an increase from the previous model. The Citation Bravo, with its efficient PW530A engines, further improved fuel efficiency, offering longer ranges and improved performance at higher altitudes.

Modifications can improve fuel efficiency by 20%
The Cessna Citation is a small-cabin (light) jet that has gained popularity worldwide for its fuel efficiency. The fuel capacity of the Cessna Citation II is 742 US gallons (2,810 litres).
Modifications can significantly improve the fuel efficiency of Cessna jets. For example, the Citation Bravo, an updated version of the S/II, features new P&WC PW530A turbofans that generate 15% more thrust at takeoff and 23% more at altitude. The PW530A engines also contribute to a more efficient fuel burn, with the aircraft burning 1,100 lb (500 kg) of fuel in the first hour and 637 lb (289 kg) in the third hour.
Another modification that improves fuel efficiency is the installation of wingtip devices such as winglets on the Citation Longitude. These wingtip devices reduce wingtip vortices and the resulting lift-induced drag, improving the aerodynamic efficiency of the wing. This reduction in drag means that the aircraft requires less thrust force to counter it, leading to improved fuel efficiency.
Additionally, Cessna offers a modification package for the Citation I that includes more powerful and fuel-efficient Williams FJ44 engines, auxiliary fuel tanks, and a modified wing. This modification allows the aircraft to fly higher, faster, and farther than newer very light jets, all while consuming less fuel. The Williams FJ44 engines are also quieter, reducing cabin noise and enhancing the overall flight experience.
Furthermore, Sierra Industries offers the Eagle II modification for the Citation I, which delivers 35% more thrust while burning 40% less fuel compared to the standard Citation I. The Eagle II also features improved climb performance, reaching a higher ceiling of 43,000 feet in just 25 minutes, compared to the 80 minutes required by the standard Citation I to reach 41,000 feet.
By investing in these modifications, owners of Cessna Citation jets can achieve significant improvements in fuel efficiency, with potential gains of up to 20% or more. Not only do these modifications reduce fuel consumption, but they also enhance the aircraft's performance, range, and overall operating efficiency, making them a worthwhile investment for those seeking to optimise their Cessna jets.
