Meets Stage 3 Noise Requirements at Key U.S. Airports Where Noise

Regulations Most Stringent, Including Florida's Naples Municipal

Airport

Really Quiet LLC today announced that it completed successful flight demonstrations of the first Gulfstream business jet aircraft to be outfitted with its Stage 3 Hush Kit at key U.S. airports. The Gulfstream GII aircraft was flown to eleven different airports across the country and met Stage 3 requirements at every location with minimal performance loss. The demonstrations took place at airports around the country, including Naples Municipal Airport in Florida, where noise regulations are extremely strict.

Really Quiet manufactures the first and only FAA-approved hush kit available for Spey-powered Gulfstream aircraft. The aircraft tested was chartered through Priester Aviation of Palwaukee, Illinois.

"We felt that to truly test our first customer's Stage 3 Hush Kit installation, we had to take the aircraft to U.S. airports that have the most stringent noise restrictions," said John Mowinski, vice president of sales for Really Quiet. "As we anticipated, the aircraft performed exceptionally well at every airport we visited, and the noise reduction we achieved was well within Stage 3 standards. Noise levels inside the cabin were also noticeably lower during take-off and even the cockpit crew noticed the difference."

Really Quiet successfully demonstrated the newly modified aircraft at airports in Van Nuys, California; St. Louis, Missouri; Tulsa, Oklahoma; Dallas, Texas; Savannah, Georgia; West Palm Beach, Florida; Naples, Florida; Pontiac, Michigan; Teeterboro, New Jersey; West Chester and West Hampton, New York. The positive results were particularly encouraging at Naples Municipal Airport in Florida, which adopted a ban on Stage 2 jet aircraft operations in January 2001. Naples serves a community that has long been one of the most vocal advocates against business jet noise.

"We are pleased to see that Really Quiet's hush kit can help the overall effort to reduce noise at Naples Municipal Airport," said Lisa LeBlanc-Hutchings, director of operations at the City of Naples Airport Authority. "The Airport Authority and the people of Naples welcome the fact that a viable solution is now available to Gulfstream GII operators who want to continue flying in and out of our community."

The Really Quiet hush kit is designed to enable Gulfstream GII, GIIB and GIII business jet models to meet stringent Stage 3 noise regulations. The company offers the only FAA-approved hush kit solution to Gulfstream II/IIB/III owners who are confronted with expanding travel restrictions related to FAR 36, Stage 3, and Annex 16 noise rules. Installation of the first Gulfstream III hush kit is to commence in September. Today, many airports around the world, including many in the United States, are limiting arrivals and departures of Gulfstream GII/IIB/III jets due to noise level concerns raised by surrounding communities. According to industry estimates, up to 80 percent of major airports may impede Spey-powered Gulfstream air travel if these aircraft are not in compliance with Stage 3 regulations.

Really Quiet anticipates receiving JAR and European regulatory approval for its hush kits in the coming months. The company is building a national network of company-approved independent service centers to install its Stage 3 hush kit, and will train personnel and monitor installations at these centers.

The Really Quiet Hush Kit is the only hush kit manufactured to incorporate a translating ejector. While in the take-off and approach configuration (ejector aft), the hush kit forces exhaust through a uniquely designed nozzle into an ejector shroud that ultimately reduces exhaust velocity, hence noise values. Once the aircraft is out of the noise sensitive area, the ejector shroud is translated forward, reducing drag and allowing the aircraft to climb out and cruise to its destination with minimum penalties. The hydraulically operated translating ejector takes two seconds to deploy and retract, and does not require any changes in cockpit readout or increase pilot workload. The redesigned thrust reverser forms an integral part of the translating ejector and is also operated by existing aircraft hydraulics.

Greatly reducing the noise of the Rolls-Royce Spey 511-8 engine, the Really Quiet Hush Kit delivers noise levels that are below today's mandated regulations. Interior cabin noise levels also are reduced. The innovative design of the hush kit also provides for easy integration into the appearance of the aircraft, eliminating concern of overall aircraft aesthetics.
