The Gulfstream G450 is the new designation and upgrade of the Gulfstream IV-SP/G400, the best-selling business jet in its class. Compared with its predecessor model, the GIV-SP, the G450 has a 463 km longer range, a pressurized cabin altitude that is more pleasant for passengers , Gulfstream’s PlaneView cockpit, new Rolls-Royce Tay 611-8C engines with full-authority digital engine control (FADEC) and a new thrust reverse system. The engines are being built by Rolls-Royce Deutschland in Dahlewitz. The G450 incorporates the most advanced avionics, cockpit displays, aircraft systems, aerodynamic enhancements and flight safety features, and retains the aesthetic design and signature windows that have set Gulfstream aircraft apart from its competition. Every aspect of the new Gulfstream G450 was designed for safety, performance, reliability and comfort.
