Gulfstream G280 Has Long Met Stringent Noise Emission Standards Gulfstream Aerospace Corp. recently announced that the Federal Aviation Administration (FAA) has confirmed that the super-midsize Gulfstream G280™ meets the certifying organization’s recently intensified noise standards. The FAA lowered the noise standards which essentially makes it tougher on jets to comply with the highest form of noise emissions. Gulfstream says that the G280 was already below the requirement standard from the inception of the aircraft. Known as Stage 5, the standard lowers the noise limit for subsonic aircraft. Official approval to the Stage 5 noise standard ensures continued operational flexibility at noise-sensitive airports and those with time-of-day entry restrictions.
