Large cabin Gulfstream aircraft now Stage Four compliant

All large cabin Gulfstream business jets have been passed as Stage Four noise compliant by the Federal Aviation Administration (FAA). The certification applies to the Gulfstream G550, G500, G450, GV, GIV-SP and GIV. These aircraft have always been Stage Four compliant but have now been formally certified as such by the FAA.

This certification is important as Stage Four certified aircraft may avoid certain restrictions based on operational noise levels being considered at several airports around the world and may be subjected to lower usage charges related to the noise levels generated by the aircraft.
