Building upon the success of the Encore, the Citation Encore+ was introduced in 2006, offering further enhancements in performance, avionics, and passenger comfort. The Encore+ continued with the Pratt & Whitney Canada PW535B engines, delivering a slight increase in efficiency and operational capability, including a range of up to 1,700 nautical miles and a cruising speed of 428 knots. One of the significant upgrades was the incorporation of the Collins Pro Line 21 avionics suite, improving the aircraft's navigation and communication systems. The cabin, designed to accommodate up to seven passengers, featured updated interiors that emphasized comfort and style, reaffirming the Encore+'s position as a leading light jet in business aviation.
