The QTA Hush Kit makes no change to the Stage 3 miminum EPR setting for take off distance.

Extensive testing of the Gulfstream aircraft in Stage 2 and Stage 3 configurations, at all flap settings, showed there is no change to climb performance with the QTA Kit installed.

Current data reported by operators has shown there to be "NO CHANGE" in range of the QTA Equipped aircraft. On short flights of 2 hrs or less a small increase in fuel burn of less than 1% has been reported.

The QTA equipped aircraft can fly any city pair that a Stage 2 aircraft can.

The Hush Kit's configuration is optimized for best performance in the speed range of 0.77 and 0.8 Mach.

"One of our requirements
was aircraft performance.
In fuel consumption, we've
seen everything form a small
reduction to a small
increase on very short legs.
It seems the heavier we are
the better it is.

On a trip from Miami to St.
Thomas, Virgin Islands we
made the round trip with a
fuel burn of just 0.9% above
the Stage 2 flight plan."

A side benefit of the QTA Hush Kit is the significant reduction in cabin noise levels. QTA has conducted before and after in flight noise tests to quantify the benefit.

Results will vary aircraft to aircraft depending upon the standard of cabin noise suppression insulation installed.

Two examples are shown, one is of a GIII already equipped with the Flight Environments advanced noise suppression system installed and the second is of a GII with the original factory insulation.

Noise measurements were taken with the Cabin to Cockpit door closed and the aft door to the rest room closed. Measurements were taken at 40,000 ft in cruise at Mach .80. Noise levels are in dB SIL (Speech Interference Level).
