As production continues for the G600, the Gulfstream G500 flight-test program also achieved several milestones to include receiving the program’s first Type Inspection Authorization (TIA) from the Federal Aviation Administration. The FAA issued the TIA for inlet compatibility and allowed Gulfstream to perform this testing for certification credit. The G500 flight-test program officially began May 18, 2015, when the first G500 flight-test article, T1, completed its first flight. Since then, T1 has reached a maximum speed of Mach 0.995, a maximum altitude of 53,000 feet/16,154 meters and recently completed its 100th flight. The test fleet, which includes four flight-test articles (T1-T4), has accumulated more than 800 hours of flying time.

The official launch of certification testing on the G500 highlights the efforts being made to achieve certification in 2017. Together, these accomplishments attest to why Gulfstream is the leader in business aviation.” T1 is focused on envelope expansion and is currently conducting flying qualities testing. The aircraft has also completed flutter testing and initial stalls and ice shapes testing.
T2 recently completed inlet compatibility testing at Eglin Air Force Base in Florida. The test exposed the G500’s Pratt and Whitney Canada PW814GA engines to high wind conditions by using a large blower, which artificially generates winds of up to 45 mph (72 km/h). The aircraft was positioned at various angles to demonstrate the engine functions properly from idle to takeoff power during crosswind and tailwind conditions. With the completion of inlet compatibility testing, T2 returned to flight loads validation and aircraft systems testing. T3 will begin testing wing anti-ice systems after just recently completing cold soak testing. As part of that testing, the aircraft made its first flight outside the United States, reaching into Canadian air space to complete the cold soak evaluation. T3 is focused on testing the all-new Symmetry Flight Deck™, the ice-protection system and various other mechanical systems.
