Gulfstream’s G500 and G600 business jet test programs are making steady progress towards anticipated Federal Aviation Administration (FAA) certification in 2017 and 2018, respectively, the airframer has announced.
Four test examples are already flying as part of the G500 test and developmental program, while the wing join of the first G600 took place last month.
“The G500 made its first flight nearly one year ago, and we have spent the 12 months since then expanding the test fleet and reaching the goals we established early on,” said Mark Burns, president, Gulfstream. “At the same time, we have made significant progress in manufacturing the five G600 test articles. Thanks to the extensive ground work in Gulfstream’s state-of-the-art test labs, these aircraft programs are maturing at a consistent pace.”
The four G500 test examples (T1-T4) have already flown more than 240 flights, surpassing 1,000 flight hours. The fifth test aircraft, P1, is presently receiving an interior for testing of cabin elements in flight. The first test example, T1 has now flown more than 500 hours and also reached a top speed of Mach 0.995, while T2 has commenced climb performance testing. Flyover noise testing is now being performed by aircraft T3, while an updated avionics system is now being tested by T4.
Gulfstream has also been making steady progress with the G600 and the wings and empennage of the first test aircraft have already been mated. “The flight-test crew and all Gulfstream employees involved in this program are keeping the G500 and G600 on track to enter into service with industry-leading safety, performance and comfort,” adds Burns.
The G500 and G600 will both have a maximum speed of Mach 0.925, the same as stable mates the G650 and G650ER.
