The Gulfstream G400™ achieves milestone first flight.
See productivity soar with the largest cabin in the class. Optimal floorplans provide up to 2.5 living areas, so you have flexible space for meetings, focused work and relaxation. Thrive in an environment of 100% fresh air—replenished every two minutes—so you arrive refreshed.
Ten windows—the largest in business aviation—offer abundant natural light and sweeping views of the world.
An exceptionally quiet cabin and the lowest cabin altitude in the class enhance your productivity.
Our clean air system purifies the cabin air using plasma ionization technology, so you can fly with peace of mind.
Discover a breakthrough formula for 21st century business success. Reaching a maximum range of 4,200 nm/7,778 km3 at Mach 0.85 cruise, the G400 delivers you to farther destinations, faster. Travel nonstop from Geneva to New York, or São Paulo to Miami, while accruing significant time savings through the year.
Advanced Pratt & Whitney engines work with our aerodynamic fuselage, clean wing and swept winglets to deliver 29% more fuel-efficiency than previous-generation aircraft.9
Gulfstream is committed to environmentally responsible business practices and the development of new technologies promoting safer, more efficient air travel. We invite you to explore the sustainability innovation story behind our aircraft.
Gulfstream’s award-winning Symmetry Flight Deck has revolutionized the way that pilots operate, vastly improving safety and efficiency. Active control sidesticks increase nonverbal communication between pilots through tactile cues. The industry’s most extensive use of touch-screen displays, paired with Phase-of-Flight intelligence, reduces pilot workload and flight startup time.
Our award-winning Predictive Landing Performance System uses real-time data to increase pilots’ situational awareness on approach. With continuously updated data, pilots can make the necessary micro-adjustments to help prevent runway overruns.
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
