The Cessna 525 CitationJet is a twin-engined corporate jet aircraft
produced by the US-American manufacturer Cessna Aircraft Company. At the NBAA Convention, the development of the six-seat Model 525
CitationJet was announced as a replacement for the model 500 Citation and Citation I.
Basically an all new aircraft, the CitationJet used a modified version of the Citation's forward fuselage,
but with a new supercritical laminar flow wing, and a new T-tail configured tailplane.
It is powered by two Rolls-Royce Williams International FJ44 turbofans, and features EFIS avionics and single pilot certification.
The CitationJet's fuselage is 27 cm shorter than the Citation I. On 29 April 1991, the CitationJet protototype N525CJ flew first's on 29 April 1991,
followed by a second (preproduction) prototype on 20 November 1991. FAA certification for single-pilot operation was received 16 October 1992, and the
first delivery toke place on 30 March 1993. Replacement Citation CJ1 announced at NBAA Convention 19 October 1998. The Cessna Citation CJ1 (also Model 525)
was developed as an improved version of the original CitationJet. The CJ1 improved on the CitationJet by adding a more-modern EFIS avionics suite and a
moderate increase in maximum takeoff weight. The first Citation CJ1 (N31CJ) was completed late 1999.
FAA certification for the Citation CJ1 was received on 16 February 2000. The CJ1 has been replaced by the CJ1+, which shares the same airframe but has
an additional updated avionics package, and FADEC to allow the engines to be controlled by computer rather than mechanical controls. The CJ1+ has a 45kg
increased in gross weight and is 37km/h faster than the CJ1 at 12,500mtrs. Cessna switched to the upgraded CJ1+ at aircraft 525-0600. The Cessna 525 CJ1+
accomodate two crew and four passengers and is powered by two Williams International FJ44-1A turbofans. The Cessna 525A CJ2 was an upgrade of model 525
(CJ/CJ1/M2) including a stretched cabin and wingspan along with increased range and payload capacity. The first delivery of the Cessna Citation CJ2 occurred
in 2000 and the series ended production in 2006. The CJ2+ was the follow-on aircraft that started production in 2005 and ended in 2016. The ICAO code for
this business jet is C525.
