Second and third Gulfstream G500 join flight test program

Gulfstream Aerospace Corp. announced that a second and third Gulfstream G500 aircraft (T2 and T3) joined the flight test campaign with successful completion of their initial flights.

T2 focuses on flight loads validation, while T3 is the main test bed for the G500 avionics systems.

T2 took off at 9:07 a.m. from Savannah-Hilton Head International Airport on Friday, Nov. 20. Flight Test pilots Kevin Claffy and Todd Abler were at the controls, and Flight Test engineers Tim Spackman and Craig Ziolkowski provided test conductor and on-board data analysis support.

Operating within the flight envelope cleared by the first G500 test aircraft (T1), T2 climbed to a maximum altitude of 43,000 feet/13,106 meters and reached a maximum airspeed of 300 KCAS/Mach 0.85. During the 3-hour-and-3-minute flight, the crew exercised all primary flight control systems, performed functional checks of the air data and cabin pressurization systems and completed a series of engine performance measurements. The aircraft landed back in Savannah at 12:10 p.m. local time.

T3 departed Savannah-Hilton Head International Airport at 2:55 p.m. on Friday, Nov. 20. At the controls were Flight Test pilots Tom Horne and Colin Miller. Flight Test engineers Grant Schoonover and Greg Vallone provided on-board support and data analysis. During the 2-hour-and-25-minute flight, the aircraft reached a maximum airspeed of 300 KCAS/Mach 0.85 and a top altitude of 45,000 ft/13,716 m. T3 landed in Savannah at 5:20 p.m. local time.

“It’s been quite a day for the flight test program with the second and third test aircraft making their first flight and T1 returning to Savannah from the National Business Aviation Association event in Las Vegas,” said Dan Nale, senior vice president, Programs, Engineering and Test, Gulfstream. “We’re very happy with the progress we’ve made. The amount of time and energy our people have invested in this program, both in the air and the labs, is what makes Gulfstream a leader in business aviation. The first flight of an aircraft attests to the fact that we’re closer to putting it into the hands of our customers and delivering on our promises.”
