Citation CJ3 vs Phenom 300: Light Jet Comparison

The Cessna Citation CJ3 is a twin-engine light business jet certified by the FAA under Type Certificate A41NM and produced by Textron Aviation. Deliveries began in 2005, and with more than 2,100 examples active worldwide the CJ3 represents one of the most mature and widely operated light jets in the segment.

The Cessna Citation CJ3 is a twin-engine light business jet certified by the FAA under Type Certificate A41NM and produced by Textron Aviation. Deliveries began in 2005, and with more than 2,100 examples active worldwide the CJ3 represents one of the most mature and widely operated light jets in the segment.

Power comes from two Williams FJ44-3A turbofans producing 2,710 lbf each, giving the aircraft a maximum takeoff weight of 12,500 lbs. That relatively light airframe enables a short-field performance figure of 3,230 feet at sea level with a 5,000-lb payload, making the CJ3 accessible to a broad range of smaller general aviation airports.

The CJ3 is single-pilot certified, and its type rating is shared across the Citation CJ1 and CJ2 family. Operators who already hold a CJ1 or CJ2 rating face a streamlined transition, which contributes to the jet's cost-effectiveness for owner-operators and small charter fleets.

At 43,000 feet service ceiling and an NBAA IFR range of 2,650 nm, the CJ3 covers most U.S. transcontinental routes and transatlantic legs with favorable winds. Fuel burn runs 195-210 gallons per hour, and all-in operating costs typically fall between $2,800 and $3,400 per flight hour depending on utilization and program enrollment.

Pre-owned acquisition cost ranges from roughly $3.5 million to $7.2 million for 2015-2022 vintage aircraft, reflecting the jet's volume and the depth of a resale market backed by 20-plus years of production.

The Embraer Phenom 300 is a twin-engine light business jet certified under FAA Type Certificate A48EM and produced by Embraer Executive Jets. First deliveries occurred in 2009, and the active fleet now exceeds 550 aircraft across corporate, charter, and fractional operators globally.

The Embraer Phenom 300 is a twin-engine light business jet certified under FAA Type Certificate A48EM and produced by Embraer Executive Jets. First deliveries occurred in 2009, and the active fleet now exceeds 550 aircraft across corporate, charter, and fractional operators globally.

Two Pratt & Whitney Canada PW535E turbofans produce 3,360 lbf each, giving the Phenom 300 a maximum takeoff weight of 15,358 lbs - approximately 2,800 lbs heavier than the CJ3. That additional thrust-to-weight ratio supports an initial climb rate of 4,000 feet per minute and contributes to the jet's 43,000-foot service ceiling.

The Phenom 300 requires its own distinct type rating (not shared with any other current production type), which carries a modest cost implication for operators transitioning from other platforms. Embraer offsets this through a well-established global training network and an active 24/7 AOG dispatch capability.

NBAA IFR range reaches 2,900 nm, placing New York-to-London on the edge of feasibility with favorable winds and allowing non-stop coast-to-coast U.S. operations with full occupancy. Maximum cruise speed is 465 KTAS with a long-range cruise of 414 KTAS. Fuel burn runs 220-240 gallons per hour, and operating costs typically land between $3,200 and $3,900 per flight hour.

Pre-owned pricing runs from approximately $4.8 million to $10.5 million for 2014-2023 vintage aircraft. The premium over equivalent-year CJ3 units reflects both the newer production baseline and the larger cabin footprint the Phenom 300 delivers.

On NBAA IFR range, the Phenom 300 holds a 250 nm advantage - 2,900 nm versus 2,650 nm for the CJ3. That margin is meaningful on transcontinental routes where payload flexibility narrows the usable range of either aircraft. For typical domestic missions inside 1,500 nm, both jets arrive with fuel to spare.

Maximum cruise speeds are nearly identical: 465 KTAS for the Phenom 300 versus 460 KTAS for the CJ3 - a 5-knot gap that works out to roughly 3-4 minutes on a typical 500 nm sector. The long-range cruise differential is slightly wider: 414 KTAS versus 401 KTAS, a 13-knot spread that pilots and schedulers will notice on legs exceeding two hours.

Both aircraft share the same 43,000-foot service ceiling, putting them on equal footing for weather avoidance and the fuel efficiency gains that come with high-altitude cruise.

Where the aircraft diverge more sharply is takeoff performance. The CJ3 lifts off in 3,230 feet at sea level with a 5,000-lb payload; the Phenom 300 requires 4,150 feet with a 6,000-lb payload. The payloads differ, so direct comparison requires mission-specific weight calculations, but operators considering airports with runway constraints below 5,000 feet should verify the Phenom 300 can meet field performance requirements at intended weights.

The PW535E engines on the Phenom 300 carry higher thrust output (3,360 lbf vs 2,710 lbf per side), which supports the jet's superior initial climb rate and slightly better single-engine performance margins - relevant for Part 135 operators with instrument departure procedures in mountainous terrain.

The Phenom 300 cabin measures 22.4 ft long by 5.5 ft wide by 5.9 ft high, yielding a total volume of 656 cubic feet. The CJ3 cabin is 20.5 ft long by 5.2 ft wide by 5.8 ft high, for 600 cubic feet. The Phenom 300 delivers 9% more cabin volume, 1.9 ft more length, 3 inches more width, and 1 inch more headroom.

Seating capacity reflects that volume difference directly. The Phenom 300 accommodates 8 passengers in typical configuration (9 maximum), while the CJ3 seats 6 in typical layout (7 maximum). For operators who regularly carry groups of 7 or 8, the CJ3 is not a viable replacement for the Phenom 300.

Baggage capacity follows the same pattern. The Phenom 300 offers 56 cubic feet of baggage volume versus 38 cubic feet in the CJ3 - a 47% increase that matters on longer trips where passengers carry golf clubs, ski equipment, or extended-stay luggage.

The Phenom 300 runs a cabin pressurization system at 6.15 psi, compared to 5.5 psi in the CJ3. At cruise altitude, that translates to a lower effective cabin altitude in the Phenom 300, which reduces passenger fatigue on longer sectors.

Embraer also cites noise levels of 73 dB at 500-ft sideline for the Phenom 300, making it one of the quieter aircraft in the light jet segment. Cessna does not publish an equivalent standardized figure for the CJ3, though the Williams FJ44 engines are generally considered quiet for their thrust class.

For groups of up to 6 passengers on routes under 1,500 nm, the CJ3 cabin functions well. Once passenger count regularly exceeds 6, or once routes require carrying both a full cabin and meaningful baggage, the Phenom 300's physical dimensions become the deciding factor.

Both aircraft use the Garmin G1000 NXi integrated avionics suite as their primary flight deck platform. Dual integrated flight management systems, synthetic vision technology, and the GFC 700 autopilot are standard on both, giving pilots a common mental model and similar procedural workload regardless of type.

The Phenom 300 packages its G1000 NXi installation under the Embraer Prodigy Glass Cockpit branding and adds two features not standard on the CJ3: an emergency descent mode in the autopilot and an optional Enhanced Vision System (EVS) for low-visibility operations. The emergency descent mode automatically initiates a descent to breathable altitude if cabin pressure anomalies are detected, a passive safety backstop that requires no crew intervention.

Connectivity differs at the standard equipment level. The Phenom 300 includes satellite phone integration (INMARSAT or Iridium) as standard equipment, along with an optional high-speed cabin data link and cabin entertainment management system. The CJ3 offers GSM/GPRS data link and satellite email capability as options rather than standard fit, meaning a used CJ3 may or may not have meaningful cabin connectivity depending on how it was configured at delivery.

Both platforms support ADS-B Out and FANS/CPDLC for oceanic and North Atlantic Track operations, which matters for operators who regularly fly over-water routes. Neither aircraft requires modifications to meet current FAA NextGen mandates.

For single-pilot operations under Part 91, the CJ3's type-rating commonality with the CJ1/CJ2 family provides a practical advantage: pilots with existing CJ family currency can step up to the CJ3 without a complete type rating from scratch. The Phenom 300's distinct type rating means a full course regardless of prior Embraer experience.

The CJ3 carries a direct operating cost of $2,800-$3,400 per flight hour against the Phenom 300's $3,200-$3,900 per flight hour. At the midpoints ($3,100 vs $3,550), the CJ3 costs roughly $450 less per hour - representing $45,000 annually at 100 hours or $225,000 annually at 500 hours of utilization.

Fuel is the primary driver of that gap. The CJ3 burns 195-210 gallons per hour; the Phenom 300 burns 220-240 gallons per hour. The 15-25 gallon per hour advantage translates to $75-$125 per hour in direct fuel savings at typical Jet-A pricing, compounding significantly at higher annual utilization.

Maintenance programs differ in structure. The CJ3's Williams FJ44-3A engines use the FJ44 FAST predictive trending program, with Cessna 12-month structured airframe checks and access to 150-plus authorized service centers globally. The Phenom 300's PW535E engines carry 5,000 flight hour or 10-year overhaul intervals, a 24-month structured check cycle, and access to 180-plus service centers including Embraer's 24/7 AOG dispatch network.

For charter operators, the Phenom 300 commands higher per-hour charter rates - $6,500-$8,500 per hour versus $5,500-$7,000 per hour for the CJ3 - reflecting the newer product positioning, larger cabin, and the premium the market assigns to aircraft with ongoing manufacturer support. This rate premium can partially offset the Phenom 300's higher operating costs for operators who charter the aircraft actively.

Acquisition cost is the other side of the ledger. The CJ3's pre-owned range of $3.5M-$7.2M sits $1.3M-$3.3M below the Phenom 300's $4.8M-$10.5M range for comparable vintages. That capital difference invested at a conservative return rate changes the total ownership math considerably, particularly for owner-operators who place high utilization but prioritize capital efficiency.

The Citation CJ3 suits owner-operators and charter startups where acquisition cost, low hourly operating expenses, and single-pilot certification define the mission. Its 2,100-strong global fleet ensures parts availability, a deep pool of trained mechanics, and strong resale liquidity. For groups of up to 6 passengers on routes up to 2,650 nm, the CJ3 executes every segment with proven, low-risk economics.

The Phenom 300 is the right choice when cabin capacity above 6 passengers, 2,900 nm NBAA IFR range, or a larger baggage allowance (56 vs 38 cu ft) are non-negotiable requirements. Charter operators who benefit from the $6,500-$8,500 per hour rate positioning and corporate flight departments that need satellite connectivity as a standard feature rather than an option will find the Phenom 300's cost premium justifiable against the operational returns it delivers.

The avionics choice does not meaningfully differentiate the aircraft - both run the Garmin G1000 NXi - but the Phenom 300's emergency descent mode autopilot and optional EVS represent genuine capability additions for operators who fly demanding IFR environments or international routes.

Neither aircraft is universally superior. If your typical mission is 4-5 passengers on 500-1,200 nm sectors and operating cost per hour is your primary metric, the CJ3 wins on economics. If you regularly fill 7-8 seats or need the 250 nm range buffer for flexibility, the Phenom 300 earns its price premium by being the aircraft the CJ3 physically cannot be.

Both compete in the same light jet segment, and both have active production lines with full manufacturer support - a reassurance that neither platform faces the parts scarcity and field support gaps that afflict older discontinued types. Selecting between them is fundamentally a mission geometry question: count your passengers, measure your typical stage length, and run the acquisition math against your projected hourly utilization.
