Gulfstream large-cabin aircraft now certified by FAA as compliant with Stage 4 noise standards

Gulfstream Aerospace Corp. announced today that the Federal Aviation Administration (FAA) recently certified the jet-maker's large-cabin aircraft to the Stage 4 noise standard. The certification applies to the Gulfstream G550, G500, G450, G350, GV, GIV-SP and GIV. These aircraft have always been Stage 4 compliant but have now been formally certified to the standard.

Stage 4-certified aircraft may avoid restrictions based on operational noise levels being considered at several airports around the world, and may be subject to lower usage charges related to the noise levels generated.

The more stringent noise requirement means the aircraft are below the maximum noise level prescribed in FAA Part 36, Stage 4.

In-production large-cabin Gulfstream aircraft will enter service with certified compliance to Stage 4 noise requirements. In-service aircraft can become compliant through an aircraft service change (ASC).
