This heavy jet delivers a cruising speed of approximately 488 mph (around 500 knots) and can operate at service ceilings up to 45,000 feet, flying above most commercial traffic. It requires approximately 1,600 meters for takeoff and 816 meters for landing.
The aircraft operates under FAA regulations, typically Part 91 for private use or Part 135 for charter operations. Pilots flying N177BB must hold a Type Rating specifically for the Gulfstream G-IV, and the aircraft is equipped with mandatory ADS-B Out technology for safe operation in high-altitude and busy airspace. Strict compliance with FAA maintenance schedules, the Airplane Flight Manual (AFM), and all placards and markings is required to ensure safe and reliable operation.
The cabin dimensions measure approximately 2.22 meters in width, 1.58 meters in height, and 13.74 meters in length. Passengers enjoy luxurious accommodations with club seating, a conference area, and divans that convert to beds. The large baggage compartment can hold up to 14 suitcases, making it well-suited for business teams, multi-generational family trips, or sports travel.
N177BB is a 1989 Gulfstream G-IVSP heavy jet with a maximum range of approximately 4,200 nautical miles, enabling nonstop routes like New York–London.
