The Cessna Citation Longitude can carry 14,300 lb of fuel in its two wing tanks
The Cessna Citation Longitude is a business jet and the largest of its kind by Cessna. The aircraft has a range of 3,500 nautical miles (6,500 kilometres) and is powered by Honeywell HTF7000 turbofans. It also features a new ~28° swept wing and a T-tail.
The aircraft's maximum takeoff weight is 39,500 lb (17,900 kg), and it has an impressive climb rate of 2,550 ft/min (13.0 m/s) at FL200. The Cessna Citation Longitude's top speed is 473 knots (876 kilometres per hour) at a maximum cruise of Mach 0.83.
The Cessna Citation Longitude is designed to make necessary chores as simple as possible for the pilot. For example, the pressurization system delivers a remarkable sub-6,000-ft cabin altitude at the aircraft's 45,000-ft maximum altitude. The cockpit, however, may seem a bit small to pilots coming from larger aircraft.

Fuel consumption is 2,400 lb for the first hour
The Cessna Citation Longitude is a business jet and the largest of its kind by Cessna. The fuel consumption of the Cessna Citation Longitude is 2,400 lb (1,100 kg) for the first hour. This is a significant amount of fuel, considering that the aircraft has a maximum takeoff weight of 39,500 lb (17,900 kg).
The high fuel consumption can be attributed to the aircraft's powerful Honeywell HTF7000 turbofan engines and its large fuel capacity. The Citation Longitude can carry up to 14,300 lb of fuel in its two integral wing fuel tanks, and if fueled using the over-wing filler caps, the total fuel capacity increases to 14,500 lb.
With a full fuel load, the Citation Longitude has a range of 3,500 nautical miles (6,500 km). This long range, combined with the aircraft's high cruise speed of Mach 0.83 (876 km/h), allows for efficient long-distance travel.
After the initial hour of flight, the fuel consumption of the Citation Longitude decreases to a more efficient 1,600-1,800 lb (730-820 kg) per hour in cruise. This lower fuel consumption allows the aircraft to maintain its long-range capabilities while optimizing fuel efficiency.
Overall, the fuel consumption of 2,400 lb for the first hour of the Cessna Citation Longitude is indicative of its powerful performance and long-range capabilities, making it a versatile and efficient business jet.

The aircraft has a range of 3,500 nmi (6,500 km)
The Cessna Citation Longitude is a business jet and the largest of its kind by Cessna. The aircraft has a range of 3,500 nmi (6,500 km). This range is facilitated by its fuel capacity, which is 14,300 lb. in two integral wing fuel tanks. This capacity can be increased to 14,500 lb. when fuelled using over-wing filler caps.
The fuel consumption of the Cessna Citation Longitude is 2,400 lb (1,100 kg) in the first hour of flight, and 1,600-1,800 lb (730-820 kg) per hour during cruise. This fuel capacity and efficiency allow the aircraft to cover long distances without refuelling.
The jet's range and fuel efficiency are also supported by its powerful Honeywell HTF7000 turbofan engines and its new ~28° swept wing and T-tail design. The aircraft's climb rate is 2,550 ft/min (13.0 m/s) at FL200, and it has a maximum cruise speed of Mach 0.83, 473 kn (876 km/h) TAS.
The Cessna Citation Longitude underwent extensive flight testing to ensure its performance and safety, accumulating over 6,000 flight hours and 11,000 test points before receiving its Type Certification from the FAA in September 2019. The aircraft's range and fuel capabilities have made it a popular choice for business and private aviation, with NetJets purchasing up to 175 Longitudes.

It took 6,000 flight hours to receive FAA Type Certification
The Cessna Citation Longitude is a business jet produced by Cessna, part of the Cessna Citation family. It remains the largest business jet by Cessna. The aircraft was announced at the May 2012 EBACE, and its first flight took place on October 8, 2016.
The Citation Longitude received Type Certification from the FAA on September 21, 2019. This certification was granted after an extensive testing process, including 6,000 flight hours, 11,000 test points, and a 31,000 nmi (57,000 km) world tour. The first aircraft was shipped in early October 2019, with deliveries to NetJets commencing on December 31, 2019.
The road to FAA Type Certification was a lengthy one, with the testing process taking place over several years. The first flight-test aircraft completed its maiden flight in October 2016, and by March 2017, three aircraft had joined the test program, accumulating over 250 flight hours. In October 2017, the test aircraft had completed more than 1,200 flight hours, and Cessna expected certification by the end of 2017 or early 2018.
However, the certification process was delayed, and in February 2018, with five aircraft in the test fleet, the total flight hours had exceeded 3,000. At this point, Cessna was granted a partial exemption for fuel tank flammability requirements to maintain its certification timeline. The exemption was valid until January 2020, but a compliance plan had to be submitted by October 1, 2018.
Despite the challenges, the Longitude program pushed forward, and by December 2018, the aircraft had accumulated over 4,050 flight hours in 1,650 test flights, leading to the award of provisional FAA type certification. This allowed Cessna to conduct flight training for customers ahead of the first deliveries.
Finally, in September 2019, after the conclusion of the 6,000 flight hours and the successful completion of all test requirements, the Citation Longitude received its full FAA Type Certification, marking a significant milestone in the aircraft's development and paving the way for its entry into service.

The Longitude's fuel tank flammability issues were resolved in December 2019
The Cessna Citation Longitude is a business jet produced by Cessna, part of the Cessna Citation family. It is the largest business jet in the Cessna lineup. The aircraft was first announced at the May 2012 EBACE, with its first flight taking place on October 8, 2016.
The Longitude received a partial exemption for fuel tank flammability requirements, which was applicable through January 2020. This exemption was necessary to keep the aircraft on track for its third-quarter approval goal. However, a compliance plan had to be submitted by October 1, 2018.
On December 5, 2019, the fuel tank flammability requirements were addressed, and the aircraft was ready for delivery. These deliveries featured the definitive installation, but they were limited to high-elevation airports or RVSM operations, and maintenance was restricted.
Textron Aviation officials anticipated Cessna Citation Longitude type certification by the end of the following month, and the FAA granted its Type Certification on September 21, 2019. This certification came after 6,000 flight hours, 11,000 test points, and a 31,000 nmi (57,000 km) world tour.
The fuel tank issue was fully resolved, and the FAA exemption served as a permanent means of full compliance with the regulation, as stated by Textron Aviation.
