摘要

The G700 is pushing forward and aiming for the sky with its flight-test program. Officially launched in 2019, the new challenger in the ultra-long-range segment is planned for 2022 deliveries. As of August, the G700 had logged more than 100 test flights, completing flutter testing and expanding the high- and low-speed areas of the flight envelope. Powered by two Rolls-Royce Pearl 700 engines at a rated takeoff thrust of 18,250 pounds, the G700 aims to present the industry's most spacious cabin, combining long range with maximum speed. Though flight test has taken it to Mach 0.99 at 54,000 feet, the G700's performance targets include an M_(MO) of 0.925 and a maximum operating altitude of 51,000 feet. Takeoff distance at sea level under ISA conditions, and maximum takeoff weight is healthy at 6,250 feet-but from that runway, you've got a lot of the globe within reach. Maximum range is currently set at 7,500 nm at Mach 0.85 (with National Business Aviation Association IFR reserves, eight passengers and four crew). Faster speed should translate into shorter overall flight hours per mission-and reduce maintenance intervals on the calendar as a result.
