Do not fill this in! ==Development== [[File:Cessna Citation X cabin interior.jpg|thumb|Double club cabin]] When the Citation X was announced, the Citation 650 series, the "family" at the top of the product line, the [[Cessna Citation III|Citations III, VI, and VII]], was eight years old. In 1990, Cessna made a proposition for an improved 650 model to their Customer Advisory Council. The council was interested in some new elements such as increased speed and a pressurized baggage compartment. This pushed Cessna toward the Citation X program, which became the new 750 series. Cessna wanted to improve the image of the Citation family. The Citation models that emerged in the 1970s were originally intended to be practical and with good handling qualities. Consequently, they turned out to be much slower than the competing [[Learjet]]s. Cessna had difficulties in shedding the popular image of the Citation as a slow airplane, even though their jets had eventually become as fast as the competition. The development of the Citation X was first announced at the [[National Business Aviation Association]] Convention in [[New Orleans]] in October 1990, with the first prototype making its maiden flight on December 21, 1993.<!--<ref name="JAWA03 p600"/>--> Originally scheduled for August 1995, the certification of the Cessna Citation X was delayed several times. First, failure of the airframe and engine to meet [[Federal Aviation Administration]] requirements caused the planned certification date postponement to late November 1995. The main delay reasons were troubles integrating the avionics and the engine to the aircraft, high-altitude and low-speed engine flameout (high wing attack angles caused insufficient airflow), engines not meeting the [[bird strike]] criteria and directional stability challenges. Efforts to increase the maximum take-off weight of the Citation X by about 800 pounds again delayed the FAA certification schedule, this time to April 1996. These changes were aimed at permitting a full-fuel payload of 1,400 pounds (seven passengers), but Cessna had difficulty achieving a balance between reducing Citation X cabin noise and minimizing the extra weight of sound-dampening materials. The certification, FAA FAR Part 25, Amendment 74, Certification 3, was finally achieved on June 3, 1996.<ref name="JAWA03 p600">Jackson, Paul. ''Jane's All The World's Aircraft 2003β2004''.

Arnold Palmer set one of them in September 1997: {{convert|473|kn|km/h}} on a 5,000 km closed course. In February 1997, the Citation X design team was awarded the [[National Aeronautic Association]]'s [[Robert J. Collier Trophy]].<!--<ref name="JAWA03 p600"/>--> The Citation X was approved by [[Transport Canada]] on May 22, 1998, and by the European [[Joint Aviation Authorities]] in 1999. In October 2000, Cessna announced an upgrade for all Citation Xs to be delivered after January 1, 2002. The main characteristics of this upgraded version were a 5% increase in thrust, a {{convert|400|lb|abbr=on}} increase in maximum take-off weight, and improved Honeywell avionics.<ref name="JAWA03 p600"/> ===Citation X+=== In 2010, Cessna initiated a major update of the aircraft, initially dubbed the ''Citation Ten'', which included upgraded AE3007C2 engines with new fans, [[Garmin G3000|Garmin G5000]] flight displays with three {{convert|14|in|cm|adj=on}} screens, and an autothrottle system. The elliptical winglets that were available as an aftermarket option on the Citation X became standard, and a stretch of {{Convert|38|cm}} was incorporated to improve passenger comfort. Due to a 1.4% improvement in [[Thrust specific fuel consumption|Specific Fuel Consumption]] (SFC) and increased thrust, the Citation X+ can support an increase in payload of {{Convert|97|kg}}, an increase in cruise speed at FL490 from 460 to 479 knots, and a range increase of 190 nmi (352 km). First flight was completed on January 17, 2012. The height has been increased to 19 ft 3 in (5.85 m), length increased to 73 ft 7 in (22.43 m), wing span has been expanded to 69 ft 2 in (21.1 m), maximum takeoff weight has increased to 36,600 lb (16,602 kg), maximum cruise speed has increased to {{convert|527|kn|mph km/h}} at FL350, and maximum range has increased to {{convert|3242|nmi|mi km}} (MTOW, Full Fuel, Optimal Climb and Descent, Mach 0.82 Cruise, FL450).<ref>{{cite web |url= http://cessna.txtav.com/~/media/files/citation/x/xsd.ashx |title=Cessna Citation X Specification and Description Preliminary |date=March 2013 |archive-url=https://web.archive.org/web/20170115235322/http://cessna.txtav.com/~/media/files/citation/x/xsd.ashx |archive-date=2017-01-15 |format=PDF |url-status=dead}}</ref> Summary: Please note that all contributions to Christianpedia may be edited, altered, or removed by other contributors.
