About the Cessna Citation Longitude

The Cessna Citation Longitude is a super-midsize business jet that entered service in 2019, representing Textron Aviation's answer to the Gulfstream G280 and Bombardier Challenger 350 in the transcontinental corporate transport market. Powered by twin Honeywell HTF7700L turbofans, the Longitude offers a 3,500-nautical-mile range at long-range cruise, enough to connect New York to London or Los Angeles to Honolulu nonstop with eight passengers. Its flat-floor cabin stretches 25 feet and seats up to twelve, with stand-up headroom and a standard double-club seating arrangement that appeals to fractional operators and corporate flight departments alike.

The type features Garmin G5000 avionics with autothrottle, synthetic vision, and advanced weather radar, making it one of the most capable Citations for single-pilot operations under appropriate regulatory frameworks. Cruise performance tops out at 476 knots true airspeed at FL450, with a service ceiling of 45,000 feet—competitive but not class-leading in a segment where Embraer's Praetor 600 and Gulfstream's G280 also vie for dominance. The Longitude's operating economics and dispatch reliability have made it popular with NetJets and other fractional providers, who value its blend of range, cabin comfort, and maintainability.
