The Cessna Citation Excel (Model 560XL) puts together the cabin width and standup headroom comfort of the Citation X in a new size package. One of the latest members of Cessna’s extensive line of Citation business jets, the Citation Excel is a turbofan-powered small-to-medium sized business jet built by the Cessna Aircraft Company in Wichita, Kansas, USA. The Citation brand of business jets encompasses six distinct families of aircraft. The Excel, the Citation XLS, and the Citation XLS+ are one of these families.

With the highly success rate of Cessna’s high-end Citation X, the company saw a market for an aircraft with the X’s features but aimed at the traditional Citation market. This aircraft was to primarily compete with twin turboprop aircrafts. The Excel was a combination of designs and technologies rather than being a direct variant of another Citation airframe. Taking the X’s wide, stand-up cabin fuselage, Cessna shortened it by about 21 feet (6.4 m) and mated it with an unswept wing utilizing a supercritical airfoil (based on the Citation V Ultra’s wing) and a Citation V’s tail.

Powering the aircraft was the new Pratt & Whitney Canada turbofan, the PW545A. The Excel, Cessna claims, has the largest cabin in its class of light corporate jets. Seated head and elbow room is designed to be greater than that in the Citation II and V, while the cabin length is similar to the Citation I, II, VI and VII. It can seat up to 10 passengers. while being flown by a crew of two.

The Citation XLS was the first “makeover” that the Excel received. Besides a glass cockpit based on the Honeywell Primus 1000 EFIS avionics suite, the XLS featured the upgraded PW545B engines with increased performance.

Cessna upgraded the aircraft again to the Citation XLS+, with the inclusion of FADEC engine controls, improved PW545C engines, and a completely revised nose design similar to that found on the Citation Sovereign and Citation X. The Citation XLS+ is the first of the XL line to feature Collins Pro Line 21 Avionics and a four tube EFIS display as divergent to the three tube Honeywell displays in the XL and XLS.

The project was announced at the annual NBAA convention in October, 1994, and the prototype aircraft took off on its first flight on February 29, 1996. Cessna had over 200 orders for the aircraft by the time FAA certification was granted in April 1998. The Wichita production line was producing an aircraft every three days by the time the 100th Excel was delivered in August 2000.
