CITATION ULTRA
In 1993, Cessna released the Citation Ultra, with the main differences being the engines, which were the latest JT15D-5D version, and the standard avionics suite, which includes a glass cockpit. The upgraded avionics include three CRT computer screens to replace the "round dial" flight instruments (one for each pilot and one center multifunction display). In 1994, the Ultra was named Flying magazine's "Best Business Jet", and remains a favorite of executive travelers around the globe today.
