GROUND RUN-UP ENCLOSURE
To ensure the safety of the traveling public, airlines maintain a stringent maintenance schedule for each aircraft. As part of this regularly scheduled maintenance, the Federal Aviation Administration (FAA) requires aircraft ground run-ups. Aircraft ground run-ups are routine aircraft engine maintenance tests, which require the operation of an engine at high power on the ground for several minutes generating continuous elevated noise levels.
Approximately 1,800 aircraft ground run-ups are conducted at GMIA every year. These tests occur during both daytime and nighttime hours. To minimize aircraft ground run-up noise, in 2002, GMIA completed construction of a massive, three-sided structure, referred to as a Ground Run-Up Enclosure (GRE). The GRE reduces aircraft engine run-up noise by more than 50% through its aerodynamic design and the use of sound reducing panels.
GMIA is only the 5th airport in the nation to employ this advanced technology to reduce noise for airport neighbors. For detailed information on the GMIA GRE, click on the links below.
