Challenger 3500 for sale, the closest modern alternative / Range: 3,400 nm / Passengers: up to 10.
The Challenger 3500 is probably the most natural comparison. Its published range is slightly shorter than the G280's 3,600 nm, while the cabin is 7 ft 2 in wide and has 106 cu ft of baggage space. It also brings a newer cabin and current-generation features such as the Nuage seat and voice-controlled cabin system.
The G280 has the edge on published range. The Challenger has the newer product.
Citation Longitude for sale, the efficiency-focused choice / Range: 3,500 nm with four passengers / Passengers: up to 12.
The Longitude comes very close on range and has a 72 in high, 77 in wide cabin. Its maximum cruise speed is 483 ktas, and it uses Honeywell HTF7700L engines.
A buyer comparing these two will likely look closely at operating economics, cabin layout and the age of the individual G280.
Praetor 600 for sale, the range leader / Range: 4,018 nm with four passengers / Passengers: typically around 8 to 9
The Praetor 600 changes the range discussion. Its published 4,018 nm range is well beyond the G280, and it adds full fly-by-wire controls and a six-foot flat-floor cabin.
If range is the first requirement, the Embraer deserves the first call.
Falcon 2000 for sale, the runway and cabin alternative / Range: 3,350 nm / Passengers: up to 10.
Dassault's Falcon 2000S is close to the G280 in range, but its large-cabin design and short-field capability give it a different character. Dassault quotes 3,350 nm with six passengers, and the 2000S was designed to retain strong runway performance while moving into large-cabin territory.
The G280 is faster at its high-speed cruise and has a slightly longer published range. The Falcon becomes more attractive when cabin volume and airport performance dominate the mission.
Legacy 500 for sale, the value-oriented comparison / Range: 3,125 nm / Passengers: up to 12.
The Legacy 500 has a similar super-midsize cabin concept and a 3,125 nm published range. It also uses Honeywell HTF7500E engines and has a 6 ft tall cabin.
Its range is shorter, but the aircraft can be very relevant in a used-aircraft search where acquisition cost and cabin space matter as much as maximum range.
