G500 and G600 Flight Test Hours Continue Their Successful Climb

After two years and 781 flights, the Gulfstream G500 test fleet has accumulated 3,041 hours in the air.

Those hours, compiled by June 15, and the successful work in the advanced research, development and testing facilities at Gulfstream’s corporate headquarters in Savannah, Georgia, have the G500 well on track for certification later this year.

The G500 test fleet includes four aircraft dedicated primarily to flight-test operations and a fifth fully outfitted production aircraft for cabin evaluation.

In May, the G500 production aircraft made its first trip to the European Business Aviation Convention & Exhibition, a little more than two years to the day of the G500’s first flight on May 18, 2015.

Smooth progress continues for the Gulfstream G600 as well. The three flight-test aircraft have flown more than 550 hours during 128 flights in the six months since the first G600 took flight. The G600 is on track for certification in 2018.

Like the Gulfstream G650ER and the Gulfstream G650, the G500 and G600 have a maximum operating speed of Mach 0.925 and a high-speed cruise of Mach 0.90.
