GIV, GV Reach Flight-hour Milestones
The Gulfstream GIV and GV fleets recently achieved significant flight-hour milestones, with both airplane fleets logging more than 4.6 million hours combined. The GIV series–which includes 669 G450s, G350s, G400s, G300s, GIVs and GIV-SPs–surpassed the 3.5 million-hour mark some 22 years after the first GIV entered service on June 8, 1987. Meanwhile, the 412-strong GV series, which includes the G550, G500 and GV, has logged more than 1.1 million flight hours since the first GV entered service on June 30, 1997. To date, the GV fleet leader has logged 13,107 flight hours, while the GIV leader has accumulated 18,403 hours. “The milestones are gratifying to all of us here at Gulfstream,” said senior vice president of programs, engineering and test Pres Henne. “They reflect the safety, performance and reliability of these aircraft.” The in-service G550/G500 fleet has a 12-month dispatch reliability rate of 99.88 percent, Gulfstream said, and the in-service G450/G350 fleet has a comparable dispatch reliability rate of 99.87 percent.
