About the Gulfstream Aerospace G400

The Gulfstream G400 represents the latest evolution in the manufacturer's mid-cabin business jet lineage, launched in 2021 to bridge the gap between the smaller G280 and the flagship G650. Powered by two Pratt & Whitney Canada PW812D engines (the same advanced powerplants found on the G500), the G400 delivers a maximum range of 4,200 nautical miles at Mach 0.85, enabling nonstop flights from Los Angeles to London or New York to Paris. The aircraft received FAA type certification in August 2023 and entered service shortly thereafter, offering seating for up to 12 passengers in a cabin that stretches 45.1 feet with a flat floor and panoramic oval windows that flood the interior with natural light.

Gulfstream designed the G400 with the company's signature Symmetry Flight Deck featuring active control sidesticks and touchscreen avionics, while the cabin altitude of 4,850 feet at FL450 and 100-percent fresh air replenishment every two minutes prioritize passenger comfort on long-haul missions. The type competes directly with the Bombardier Challenger 3500 and Dassault Falcon 2000LXS in the super-midsize segment, distinguished by its higher cruise speed (Mach 0.90 maximum operating speed) and longer legs. As a clean-sheet design rather than a derivative, the G400 incorporates advanced aerodynamics including winglets optimized for transonic efficiency and a fuselage cross-section that maximizes cabin volume while minimizing drag.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
