Overview
The current G400 uses PW812GA engines and the Symmetry flight deck in a cabin sized for up to two-and-a-half living areas. Gulfstream’s preliminary design target is 4,200 nautical miles at Mach 0.85 under specified mission assumptions.
Program history
The programme brings the company’s newer cockpit and airframe architecture to a lower position in its large-cabin range. It is separate from the legacy Tay-powered G400 sold in the early 2000s.
