The Citation V was also the first Citation with an electronic flight instrument system (EFIS) offered as standard equipment, albeit only on the captain's side.

of the original Citation 500. Softer landing trailing link main landing gear reduced fuel tank capacity to 5,440 pounds, 360 pounds less than the Ultra's, but it has more range. The wheel track was narrowed 3.7 feet for better ground tracking and easier crosswind landing. The wing leading edge is de-iced by Bleed air. Boundary layer energizers and a stall fence improve stall characteristics. Pressurization is digitally controlled and brake modulation is improved. Redesigned interior fittings and passenger seats provide more seated headroom. Passenger service units provide more even airflow and temperature control. MTOW increases by 330 pounds to 16,630 pounds, to carry five passengers with full fuel, lengthening takeoff from the 3,180 feet needed by the Ultra. The improved PW535 high altitude thrust allow the Encore to climb faster and cruise higher.
