Bombardier Global 5500 for sale / Range: 5,900 nm / Passengers: Up to 16.
The Global 5500 stretches the mission farther than the G500 and has a similar large-cabin role. Bombardier lists a 5,900 nm theoretical range, Mach 0.90 top speed and 51,000 ft maximum operating altitude. Its Rolls-Royce Pearl 15 engines are a major part of the package.
Choose the Global 5500 when additional range is important. The G500 becomes more attractive when speed, Gulfstream's cockpit and its particular cabin layout carry more weight in the decision.
Dassault Falcon 6X for sale / Range: 5,500 nm at Mach 0.80 / Passengers: Up to 16.
The Falcon 6X is a very serious comparison. It has a wider 8 ft 6 in cabin, 1,843 cu ft of cabin volume and a 5,500 nm published range. Dassault also gives it strong short-field credentials, including steep-approach capability.
The 6X is the aircraft to examine if cabin width and airport access are high on the list. The G500 counters with a higher maximum operating speed of Mach 0.925 and a flight deck that has already established itself across Gulfstream's newer large-cabin family.
Gulfstream G600 for sale / Range: 6,600 nm / Passengers: Up to 19.
This is the closest family comparison. The G600 keeps the Symmetry Flight Deck, active sidesticks, 51,000 ft ceiling and Mach 0.925 maximum operating speed, but adds roughly 1,300 nm of published range and more cabin volume.
If the extra cabin and range are regularly used, the G600 is the logical move. If they are not, the G500 avoids carrying capability you may rarely use.
Bombardier Challenger 650 for sale / Range: About 4,000 nm class / Passengers: Typically around 10 to 12, depending on configuration.
The Challenger 650 sits in a different size and generation of aircraft. It is worth comparing because buyers moving up from a Challenger often look at the G500 as a major step into the large-cabin segment.
The G500 is faster, flies higher and has a substantially larger cabin, while the Challenger's appeal is its mature platform and different operating profile.
Embraer Praetor 600 for sale / Range: 4,018 nm with four passengers and NBAA IFR reserves / Passengers: Up to 12.
The Praetor 600E is smaller, but it deserves a place on the shortlist because it can cover a surprising number of missions at a lower aircraft size. Embraer publishes 4,018 nm of range, Mach 0.83 MMO and a 45,000 ft maximum operating altitude.
If the mission rarely exceeds 4,000 nm and the owner does not need a large-cabin Gulfstream, the Praetor deserves serious consideration. Once passenger count, cabin space and longer missions become routine, the G500 moves into a different category.
