New Gulfstream G500 joins business aviation convention

Gulfstream Aerospace Corp.'s all-new Gulfstream G500 made its first cross-country trip for the 2015 National Business Aviation Association's Business Aviation Convention & Exhibition (NBAA2015). The flight test aircraft arrived at Henderson Executive Airport on Friday to join the G650ER, G550, G450, G280 and G150 in Gulfstream's static display.

The G500 flew from Savannah/Hilton Head International Airport into 75-knot headwinds and arrived at Henderson Executive 4 hours and 36 minutes later, accomplishing the 1,630-nautical-mile flight at an average speed of Mach 0.85 and altitude of 45,000 feet. Gulfstream test pilots Scott Martin and Scott Evans were at the controls, with Flight Test engineers Paul Ludlow and Nathaniel Rutland providing on-board support.

The G500 flew to Las Vegas with a significant amount of flight testing equipment on board:

• a noseboom, which provides air data, angle-of-attack and angle-of-sideslip information to the pilots and engineers.
• Attitude Recovery System (ARS) safety equipment for high-speed flutter testing and low-speed stall testing.
• data-monitoring system that provides real-time data for engineers on board and in the telemetry room.
• a video recording system that captures touchscreen commands and flight-deck footage as well as external footage of the landing gear, trailing cone and ARS.
• flutter vanes on the wing and horizontal tips.

The first G500 test aircraft, T1, is focused on flight performance and controls and has achieved a number of flight-test milestones since its first flight on May 18. The aircraft has flown more than 160 hours, completed 44 flights and reached an altitude exceeding 50,000 ft. Its longest flight was 5 hours and 22 minutes. T1 has reached a top speed of Mach 0.995. Flutter and envelope expansion testing are in progress, and initial testing of the aircraft's handling qualities and the high-speed and recovery stall system have also taken place.

In total, the G500 flight-test program consists of five aircraft, including a fully outfitted production aircraft that allows the company to test all the interior elements and complete integration of the aircraft systems with the passenger experience. T2 and T3 have been delivered to the Flight Test facility and are preparing for first flight.

Gulfstream anticipates certification of the G500 in 2017, with entry into service in 2018. Lab testing for the G600 is ongoing in Gulfstream's integration test facility, with certification slated for 2018 and entry into service in 2019.
