Gulfstream G450 Vs. Challenger 300

If you’re looking for private jet options that provide maximum comfort and cabin space as well as superb long-range performance, the Gulfstream G450 and Bombardier Challenger 300 are both excellent choices—though both aircraft offer slightly different experiences. Below, we’ll compare the stats and capabilities of these two aircraft to help you decide which best fits your mission.

If you want to travel longer distances non-stop with a larger group, the G450 is a great option—especially if you need to stay connected and ready for your next meeting while in the air. This heavy jet was designed for business productivity, and its seven-channel satellite communication system with satellite phone, Wi-Fi, printer, and fax are perfect features for the global company that needs to stay linked to the rest of the world. The cabin also comes complete with advanced sound suppression technology for a quieter flight experience. Its impressive maximum range and high cruise speed put international destinations at your fingertips faster than ever before, and with 100% oxygen pumping through the cabin every two minutes, you’ll arrive feeling rested and ready.

The Bombardier Challenger 300 is a leader among super-midsize jets in fuel efficiency, speed, and range. Typically transporting eight passengers, the Challenger 300 can handle non-stop, coast-to-coast legs at high speed and with a low operating cost. It can depart from shorter airfields than many jets in its category, opening up even more destinations. In its roomy cabin, each fully-adjustable seat features fold-out work or dining tables, plus individual power plugs.

The G450 features Gulfstream’s PlaneView avionics system on four large LCD displays, controlled by the pilots via a cursor in their seats’ armrests. Additionally, the G450 includes the Kollman enhanced vision system (EVS), which uses a nose-mounted infrared camera to help pilots spot terrain and runway lights at night or in inclement weather.

The flight deck features Rockwell Collins Pro Line 21 avionics system, displayed across four LCD screens. The system comes standard with an Engine Indication and Crew Alerting System. This gives pilots engine performance information such as fuel flow, oil and turbine temperatures, and environmental control information.
