Putting the Long in Longitude

Textron Aviation subsidiary Cessna has delivered the one-hundredth Citation Longitude business jet to an undisclosed but reportedly longtime Citation customer. Textron Aviation employees celebrated the milestone with a special celebration at the company’s Wichita, Kansas headquarters.

Textron Aviation senior vice-president of Global Sales and Flight Operations Lannie O’Bannion stated: “The Citation Longitude’s performance, efficiency and unrivaled cabin experience have already made it a legendary aircraft in its segment. We’re proud of this significant delivery milestone and of our talented team who continues to design and deliver the best aviation experience for our customers.”

Announced at 2012’s EBACE convention and FAA type-certified in 2019, Cessna’s Citation Longitude is a super-midsize business aircraft comprising design cues from numerous and proven Textron aircraft models. An evolution of Cessna’s Latitude business jet, with which it shares a fuselage cross-section, the Longitude sports new 28° swept wings incorporating moderate winglets, a T-tail empennage, and area-rule fuselage contouring. All told, the Longitude’s aluminum fuselage and wing are similar to those of the Hawker 4000—albeit longer and of greater span respectively.

The Citation Longitude’s design makes use of numerous up-to-the-minute technologies such as redundant integrated autopilot and auto-throttle systems with emergency descent mode (EDM). The aircraft is powered by a pair of FADEC-equipped Honeywell HTF7700L turbofans each producing 7,665 lbf-thrust. So motivated, the Longitude manages a Vne of 560-knot (0.84 Mach), a cruise speed of 483-knots (0.72 Mach), an unrefueled range of 3,500-nautical-miles, and a service-ceiling of FL450.

Longitude operators benefit from the model’s on-condition engine overhaul periods and best-in-class 18-months/800-hours (whichever occurs first) airframe service intervals. Textron Aviation's full-time diagnostics recording system (AReS) and 3D technical publications significantly reduce maintenance downtime and overall operating costs.

Cessna’s Citation Longitude is a moderately large aircraft, the fuselage of which measures 73-feet, two-inches in length; six-feet high; and six-feet, five-inches wide. The Longitude’s semi-super-critical wing spans 68-feet, 11-inches.

Type-certified for two-pilot operation, the Longitude may be configured to comfortably accommodate eight (standard) to 12 (maximum) passengers. The aircraft’s 39,500-pound Maximum Gross Take-Off Weight (MGTOW) includes 14,500-pounds of fuel and a full-fuel payload of 1,600-pounds. The Longitude’s spacious, 112-cubic-foot walk-in baggage compartment is in-flight accessible and has a capacity of 1,115-pounds.

At its service-ceiling, the Longitude’s pressurization system maintains a comfortable 4,950-foot cabin.

The Citation Longitude features Garmin’s G5000 Flight-Deck, which offers pilots complete touchscreen control of the aircraft’s navigation and communication systems. The avionics suite includes a trio of large, high-resolution LCD displays; four touchscreen controllers; Garmin Synthetic Vision Technology (SVT); synoptics for key systems; in-flight diagnostics reporting; fully-integrated auto-throttles; Required Navigation Performance Authorization Required (RNP AR) to 0.3-nautical-miles; ADS-B Out/In; and optional FANS 1/A and Link 2000+ CPDLC capabilities.
