Cessna Citation Longitude vs Bombardier Challenger 350

The Cessna Citation Longitude is Textron Aviation's largest business jet in the Citation family, certified under FAA Type Certificate T00032NM (model designation 700) and EASA TCDS EASA.IM.A.620. It entered service in 2017 as the flagship of the Citation line, designed to bring super-midsize range and a stand-up flat-floor cabin to buyers who wanted a Cessna product rather than a Bombardier or Gulfstream.

Power comes from two Honeywell HTF7700L (AS907-2-1S) turbofans producing 7,665 lbf of takeoff thrust each - the highest thrust-per-engine figure in the Citation range. That combination supports a published NBAA IFR range of 3,500 nm at Mach 0.80 cruise with four passengers and reserves, making it capable of nonstop coast-to-coast US trips with meaningful fuel reserves even into headwinds. Maximum cruise speed is 483 KTAS at Mach 0.84, which edges above the Challenger 350's 470 KTAS.

The Longitude's maximum takeoff weight of 39,500 lb is about 1,100 lb below the Challenger 350, but the Longitude carries slightly more usable fuel: 14,511 lb (2,166 gallons) in two wing tanks versus the Challenger 350's 14,150 lb. Takeoff field length at sea-level ISA conditions from MTOW is 4,810 ft, essentially identical to the Challenger 350's 4,835 ft. Maximum operating altitude for both aircraft is 45,000 ft.

The cockpit is a major differentiator. The Longitude flies with Garmin G5000, featuring three 14-inch landscape touchscreen displays, four touchscreen controllers, dual Garmin FMS with LPV, RNP, and GLS approach capability, dual GPS/IRS with SBAS/WAAS augmentation, synthetic vision standard, and ADS-B In and Out from the factory. The G5000's touchscreen interface and Garmin ecosystem integration represent a different design philosophy from the button-driven Pro Line 21 Advanced in the Challenger 350, and most crews coming from modern GA or turboprop aircraft find the transition to G5000 intuitive.

The Longitude's ICAO type designator is C700. The FAA type rating is CE-700, a standalone rating not shared with other Citation variants. The aircraft has been in service since 2017, with approximately 115 active airframes in the global fleet according to JETNET data, the majority operated by NetJets and high-net-worth owner-operators.

The Bombardier Challenger 350 succeeded the Challenger 300 in 2014, sharing the same Transport Canada Type Certificate (FAA TCDS T00005NY, model designation BD-100-1A10) and cabin cross-section while addressing the areas operators most wanted improved: range, useful payload, and cockpit technology. Bombardier delivered the Challenger 350 for eight years before replacing it with the Challenger 3500 in 2022.

The Challenger 350 is powered by two Honeywell HTF7350 turbofans rated at 7,323 lbf of thrust each, flat-rated to ISA +15 degrees C. NBAA IFR range is published at approximately 3,200-3,250 nm with 8 passengers and NBAA reserves, making it comfortably capable on transcontinental US missions and Caribbean routes. Maximum cruise speed is 470 KTAS (Mach 0.82-0.83), with long-range cruise at approximately 459 KTAS.

The Challenger 350's signature advantage is its cabin width. At 7 ft 2 in, it is the widest cabin in the super-midsize class, 9 inches wider than the Longitude. That width allows a true double-club seating arrangement with lie-flat seat conversion, a certified seat count up to 10 passengers, and a cabin feel that buyers frequently describe as closer to a large-cabin aircraft. Cabin height is 6 ft 1 in with a flat floor throughout.

The cockpit runs Rockwell Collins Pro Line 21 Advanced: four LCD displays, dual FMS with LPV and RNP approach capability, dual GPS/IRS with WAAS, MultiScan weather radar, and synthetic vision standard. Optional equipment includes a head-up display (HUD) and Enhanced Vision System, neither of which is available on the basic Longitude without additional configuration.

Type rating for the Challenger 350 is CL-30, which covers both the Challenger 300 and Challenger 350 - a practical advantage for operators who already have CL-30-rated crews from Challenger 300 operations or for flight departments looking to maintain a single type rating across a mixed fleet. The ICAO designator is CL35. With 380+ aircraft globally and over 210 in the US, the Challenger 350 has a significantly deeper service and support network than the Longitude.

The Longitude's 3,500 nm NBAA IFR range is its most frequently cited advantage over the Challenger 350's approximately 3,200-3,250 nm. That 250-300 nm gap translates to about 30-35 minutes of additional flight time at Mach 0.80 cruise, which can determine whether a given route is nonstop or needs a fuel stop. New York to Los Angeles runs approximately 2,450 nm great circle, well within both aircraft's range. The Longitude's extra margin becomes relevant on westbound transcons against headwinds, Atlantic crossings, or high-altitude routes where headwind components eat into reserves.

Raw cruise speed slightly favors the Longitude. Its published maximum cruise speed of 483 KTAS (Mach 0.84) is about 13 knots faster than the Challenger 350's 470 KTAS. At 3,000 nm, that difference equates to roughly 10-12 minutes faster block time. It is a real advantage, though most super-midsize buyers do not choose between aircraft primarily on the basis of 10 minutes on a long flight.

Both aircraft are certified to 45,000 ft. Takeoff field performance at sea-level ISA conditions is nearly identical: the Longitude requires 4,810 ft from MTOW, the Challenger 350 requires 4,835 ft. Neither figure distinguishes the two on realistic route planning to typical business aviation airports.

The Challenger 350's canted winglets, absent on the Longitude, improve aerodynamic efficiency and aid climb to altitude, allowing direct climb to FL430 in some conditions. The Longitude's straight-wing aerodynamics reflect the Citation design tradition of clean, efficient wing profiles rather than winglet-driven efficiency gains.

For operators whose primary missions are 1,500-2,500 nm, both aircraft are more than capable, and neither will feel range-limited on typical US domestic or Caribbean sectors. The Longitude's range advantage becomes operationally meaningful above roughly 2,800-3,000 nm or on international routes where fuel planning margins are tighter.

Cabin length is identical on paper: both aircraft measure 25 ft 2 in from bulkhead to bulkhead. The critical difference is width. The Challenger 350's 7 ft 2 in cabin is 9 inches wider than the Longitude's 6 ft 5 in, a gap that changes the seating geometry significantly. The Challenger 350 can configure a full double-club in opposing four-seat groups facing each other across a meaningful aisle. The Longitude's narrower cross-section still supports club seating, but with less aisle width and a feel that is closer to a midsize than a large-cabin aircraft on the cabin floor plan.

Cabin height is essentially equal: the Longitude offers exactly 6 ft 0 in of stand-up headroom, the Challenger 350 offers 6 ft 1 in. Both qualify as flat-floor, stand-up cabins, which differentiates both from older midsize jets that required stooping.

Seating configurations favor the Challenger 350 for group travel. Its wider cabin and double-club layout supports 8-10 passengers in typical certified configurations. The Longitude typically certifies for up to 12 passengers per the EASA TCDS, but a realistic double-club layout seats 8, and the narrower cabin makes higher counts a tighter fit than on the Challenger 350.

Where the Longitude makes its cabin case is in seat quality and sleep capability. The Longitude's seats are fully berthable at 180 degrees for up to four passengers, and pitch at 30 inches. For two or three passengers on a long overnight sector, the ability to sleep flat in a seat is a genuine differentiator. Challenger 350 seats also recline to flat, so sleep capability is comparable, though Longitude operators frequently cite berthability as a mission-defining feature.

Baggage capacity is identical at 106 cu ft on both aircraft. The Longitude's baggage compartment is in the tail cone and externally accessible. The Challenger 350 also offers 106 cu ft with in-flight access through an internal door on some configurations, which matters on longer missions where passengers want access to bags in cruise.

Interior ambiance differs by brand philosophy. The Longitude reflects Textron's Citation design language: clean, modern finishes, larger oval windows, and a Garmin-integrated cabin management system with iPad-based controls. The Challenger 350 uses Bombardier's slide-ledge passenger control units and a more traditional corporate cabin aesthetic. Both can be configured to a high standard, and individual aircraft condition matters far more than brand differences in the pre-owned market.

The avionics choice is one of the clearest functional differences between the two aircraft. The Longitude flies with Garmin G5000: three 14-inch landscape touchscreen displays, four GTC touchscreen controllers, dual Garmin FMS with LPV, RNP, and GLS approach capability, dual GPS/IRS with SBAS/WAAS augmentation, Garmin GWX 75 weather radar, and Synthetic Vision Technology (SVT) standard from the factory. ADS-B In and Out are standard equipment. An optional Garmin Enhanced Vision System (EVS) adds a forward-looking infrared camera overlay on the synthetic vision display.

The Challenger 350's cockpit runs Rockwell Collins Pro Line 21 Advanced: four LCD displays in a traditional PFD/MFD arrangement, dual FMS, dual GPS/IRS with WAAS, MultiScan weather radar with automatic tilt, and synthetic vision standard. Optional equipment includes a head-up display and Enhanced Vision System - a capability the base Longitude does not offer from the factory, though Garmin's EVS option addresses part of that gap.

For crew training and currency, the avionics choice matters. Pilots transitioning from modern turboprops, piston twins, or other Citation jets with Garmin equipment generally find the G5000 interface familiar and require less initial adaptation. The Pro Line 21 Advanced is a mature, well-supported platform widely known in the super-midsize segment, and crews with Challenger 300 or other Pro Line aircraft will find the Challenger 350 cockpit familiar.

Both aircraft support standard RVSM operations and ADS-B Out compliance. ADS-B Out is standard on the Longitude from first delivery; on earlier Challenger 350 examples it may be a retrofit item. When evaluating a pre-owned Challenger 350, confirm ADS-B Out compliance and Pro Line 21 Advanced software currency, since both can require work on early production examples and should factor into total acquisition cost.

Fuel burn figures from operator and broker sources put the Longitude at approximately 275-300 gallons per hour at typical cruise power and the Challenger 350 at approximately 270-290 GPH. At an average jet fuel price of $7 per gallon, that works out to roughly $1,925-$2,100 per hour for the Longitude versus $1,890-$2,030 for the Challenger 350, a difference of $35-70 per hour that is unlikely to drive buying decisions at the aircraft acquisition level. These are operator-reported estimates, not manufacturer-published figures.

Both aircraft use Honeywell HTF7000-series engines. The Longitude's HTF7700L and the Challenger 350's HTF7350 are both eligible for Honeywell's MSP (Maintenance Service Plan) engine program, the most common coverage structure in the super-midsize segment. Program enrollment is strongly recommended for either aircraft to manage unscheduled engine costs.

Acquisition cost is where the two aircraft diverge most sharply. Pre-owned Challenger 350s from the 2016-2021 model years trade in the $11M-$15.5M range. Pre-owned Longitudes from 2018-2022 typically trade $18M-$26M depending on total time and program enrollment, with an average around $21.5M. The roughly $6M-$10M acquisition gap between comparable-year examples of each aircraft is the single largest cost difference for most buyers.

Total operating cost per flight hour is estimated at $5,800-$7,500 for the Longitude and $7,200-$9,100 for the Challenger 350, based on approximately 300 annual flight hours including fixed costs. Individual aircraft condition and program status drive more variation than the model itself. Buyers should work through a detailed cost comparison using their specific mission profile and each candidate aircraft's maintenance program enrollment before drawing firm conclusions.

Choose the Cessna Citation Longitude if range, avionics, and seat comfort on long legs are your priorities. Its 3,500 nm NBAA IFR envelope outreaches the Challenger 350 by 250-300 nm, the Garmin G5000 cockpit is one of the most modern in the super-midsize class, and the fully berthable seats give it a genuine overnight flying capability for two to four passengers. It suits owner-operators who fly long transcontinental or transatlantic missions and prefer the Garmin ecosystem or a Textron Aviation support relationship.

Choose the Bombardier Challenger 350 if cabin volume and passenger count matter more than range margin. At 7 ft 2 in wide and 860 cu ft of volume, it is the widest and roomiest super-midsize on the market, and it can seat 10 passengers in a certified double-club configuration that no Citation achieves. For flight departments that regularly move eight to ten people, the Challenger 350 is the functional choice. The larger pre-owned fleet, established CL-30 pilot pool, and $6M-$10M lower acquisition cost versus a comparable Longitude year are also compelling arguments.

Buyers often focus on spec sheet comparisons, but the practical decision usually comes down to two questions: how often do you carry more than six or seven passengers, and how often do you need nonstop range beyond 3,000 nm? If you regularly fill 8-10 seats, the Challenger 350's wider cabin matters every flight. If you regularly fly routes where 3,200 nm is tight, the Longitude's extra range matters more than cabin width.

Neither aircraft is objectively better. The Longitude is the more modern design with superior avionics and more range. The Challenger 350 is the wider, more spacious cabin with more inventory on the pre-owned market, a lower entry price, and deeper service network. A review of specific aircraft maintenance program status, total time, and avionics configuration will matter more to the final buying decision than any spec sheet comparison.
