Bombardier Challenger 604 for sale:
Range: around 4,000 nm / Passengers: typically 10, with configurations up to 12.
The Challenger 604 is a much larger aircraft and belongs in the comparison when the buyer needs substantially more range and cabin space. It uses GE CF34-3B engines and a Pro Line 4 flight deck on the original configuration.
The 800XP wins on being smaller and simpler for the buyer who does not need a large-cabin jet. The Challenger wins decisively once the mission moves toward long-range international travel.
Bombardier Learjet 60 for sale:
Range: 2,418 nm with four passengers; 2,186 nm / Passengers: usually 6 to 7.
This is the closest classic comparison. The Learjet is faster and climbs harder, while the Hawker gives you 551 cu ft of cabin volume against 447 cu ft in the Learjet. The Hawker also has the longer cabin.
If the buyer spends more time looking at the cockpit than the cabin, the Learjet becomes attractive. If eight passengers are regular, the Hawker deserves serious consideration.
Cessna Citation Excel for sale: Range: 1,839 nm / Passengers: typically 7.
The Excel is smaller inside, with a 5.5 ft wide, 18.5 ft long cabin. Its straight-wing design gives it strong runway performance, and AOPA notes the large baggage compartment and broad Citation service network as practical advantages.
For shorter trips, the Excel is a very logical alternative. The Hawker has more cabin and more range.
Cessna Citation XLS+ for sale:
Range: around 2,100 nm / Passengers: typically 8.
The XLS+ is much newer and uses Pratt & Whitney Canada PW545C engines with Collins Pro Line 21 avionics. Its cabin is 5.5 ft wide and 18.5 ft long.
That is the cleanest answer for a buyer who wants newer systems and a newer airframe. The Hawker's argument is the larger cabin and lower acquisition cost of an older aircraft.
Dassault Falcon 50 for sale:
Range: around 3,200 nm / Passengers: typically 9.
The Falcon 50 is a different proposition. It has three engines, a 23.5 ft cabin and a 6.1 ft cabin width in AvBuyer's current data. Dassault's own history confirms the three-engine configuration and the aircraft's long-range design.
For demanding long-range or hot-and-high missions, the Falcon is in another league. The 800XP is the more straightforward choice when the mission fits inside its range.
