The Citation Jet is the perfect choice for anyone looking for an entry-level private business jet. It is designed to be extremely economical, both in purchase price and operating costs: the CJ’s systems are simple, making it easy to fly and operate by a single pilot.
The increased speed, due to the reduced drag on the wings, is augmented by the speed provided by two Williams/Rolls-Royce FJ44-1A engines. Williams/Rolls Royce used to produce engines for cruise missiles, and was able to produce engines that generated 1,900 pounds of thrust each, while being aerodynamic and light enough for the CJ. The FJ44 engines were simplified to have a third of the moving parts that most engines of that time did, as well as burning about 30% less fuel than comparable jet engines.
