New engines take your aircraft performance to a new level

With its advanced supercritical wing configuration, the Citation S-II is an ideal candidate for the increased power of Williams FJ44-3A engines. Boost your sea-level thrust by nearly 1,000 pounds, and increase your range to more than 2,600 nautical miles. And that’s just the beginning.

•  Cruise speed as much as 50 knots faster
•  Fly 400 miles farther at maximum cruise power
•  Fly 600 miles farther at economy cruise power

Digital engine control for Cessna Citation safety
These engines aren’t all brawn — their brains come in the form of full authority digital engine control (FADEC) for full-time syncing the two engines giving you comprehensive power management. The smarter your engines are, the easier to fly and safer your plane is.
