The Gulfstream G550 is a long-range heavy jet with a 6,328 nautical mile range and seating for up to 18 passengers. One of the most produced large-cabin jets in history, the G550 features a PlaneView cockpit, enhanced vision system, and a cabin altitude of just 6,000 feet at 45,000 feet — reducing fatigue on long flights.
