Gulfstream G650 Family Surpasses 75 Speed Records The Gulfstream G650 family of ultra-longrange executive jets continue to pile on speed records and other achievements since entry into service back in 2012. Gulfstream highlights that this jet family has flown past 75 speed records and also has been working on steep-approach certification now. Operating into airports like London City (LCY) requires steep-approach certification because of stringent noise abatement measures at the airport. Often times the approach is at a steep 5.5 degree angle. Most airports tend to be 3 degrees. Additionally the runway is fairly short offering only 4,329-feet.
