Washington, DC from 1 p.m. to 3 p.m. 

Attendees are encouraged to either come 

early or stay later to visit the Gulfstream 

Aerospace Corporation (Gulfstream) 

Supersonic Acoustic Signature 

Simulator (SASSII) that will be outside 

of the Department of Transportation 

(DOT) building.

Background: Since March 1973, 

supersonic flight over land by civil 

aircraft has been prohibited in the 

United States. The Concorde was the 

only civil supersonic airplane that 

offered service to the United States, but 

that airplane is no longer in service. 

The interest in supersonic aircraft 

technology has not disappeared. Current 

research is dedicated toward reducing 

the impact of sonic booms as they reach 

the ground, in an effort to make 

overland flight acceptable. Recent 

research has produced promising results 

for low boom intensity, and has 

renewed interest in developing 

supersonic civil aircraft that could be 

considered environmentally acceptable 

for supersonic flight over land. 

The FAA has held three previous 

public meetings. The first meeting was 

held in Chicago, IL on Friday, October 

24, 2008, as part of the O’Hare Noise 

Compatibility Commission Symposium. 

The second meeting was held in Palm 

Springs, CA on Sunday, March 1, 2009, 

as part of the Annual University of 

California Symposium on Aviation 

Noise and Air Quality. And, the third 

meeting took place on Wednesday, 

April 21, 2010, as part of the joint 

meeting of the 159th Acoustical Society 

of America and NOISE–CON 2010 in 

Baltimore, Maryland 21202. 

The purpose of these meetings is to 

raise public awareness on advances in 

supersonic technology, and for the FAA, 

the National Aeronautics and Space 

Administration (NASA), and industry to 

get feedback from interested persons. 

Highlighting the effort to raise 

awareness, Gulfstream has supported 

the FAA’s public meetings by making its 

Supersonic Acoustic Signature 

Simulator II (SASSII) available for 

attendees to visit. The SASSII is a 

mobile audio booth designed and 

equipped to demonstrate the 

‘‘Gulfstream Whisper’’, the aerospace 

company’s latest effort to provide a 

solution to the traditional sonic boom. 

A supersonic aircraft such as the 

Concorde in cruise produces a 

traditional jagged ‘‘N-wave’’ sonic boom 

pressure wave, resulting in a loud, 

jarring double boom on the ground as it 

passes by. Gulfstream’s patented spike 

for controlling and reducing sonic boom 

transforms the traditional N-wave sonic 

boom into a smooth and more rounded 

pressure wave shaped roughly like a 

sine wave or a sideways ‘‘S’’. This 

change in the wave shape results in a 

softer sound that is quieter than the 

Concord sonic boom by a factor of 

10,000. Gulfstream developed the 

mobile SASSII so others could 

experience this dramatic sound 

difference. The simulator enables 

visitors to sense for themselves the 

dramatic difference in sound, 

reverberation, and intensity. Using a 

sophisticated, computer-based audio 

system, the acoustic engineer sends the 

audio feed into a sound booth where 

visitors can compare various sound 

signatures. 

Public involvement is essential in any 

future definition of an acceptable new 

standard that would allow supersonic 

flights over land. We anticipate that this 

will be one of many meetings informing 

the public on the continual 

developments in the research of shaped 

sonic booms and other technical and 

environmental challenges that need to 

be addressed in developing a new 

supersonic airplane.

Transportation Safety Approval 

Performance Criteria 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notification of criteria used to 

evaluate the Zero Gravity Corporation 

(Zero Gravity) safety approval 

application. 

SUMMARY: The FAA issued Zero Gravity 

a safety approval, subject to the 

provisions of Title 51 U.S.C Subtitle V, 

ch. 509, and the orders, rules and 

regulations issued under it. Pursuant to 

14 CFR 414.35, this Notice publishes the 

criteria that were used to evaluate the 

safety approval application. 

Background: Zero Gravity applied for, 

and received, a safety approval for its 

capability to provide a reduced gravity 

environment using a Boeing 727 aircraft. 

The performance criteria for this safety 

approval are applicant developed per 14 

CFR 414.19 (a)(4). Zero Gravity is 

capable of replicating three reduced 

gravity levels associated with suborbital 

space flight. The reduced gravity levels 

are: 

—0.00 g ± 0.05 g for 17 continuous 

seconds. 

—0.16 g ± 0.05 g for 20 continuous 

seconds. 

—0.38 g ± 0.05 g for 20 continuous 

seconds. 

Criteria Used To Evaluate Safety 

Approval Application: The reduced 

gravity environment provided by Zero 

Gravity was evaluated by the FAA as a 

component of a flight crew qualification 

and training process. The evaluation 

included the FAA’s assessment of Zero 

Gravity’s ability to accurately replicate 

the specified reduced gravity levels. 

Zero-G submitted the following data 

to show how they were in compliance 

with the criteria: 

—Parabolic Aircraft Acceleration 

Measurement System (PAAMS) power 

and calibration procedures, 

—Parabolic Aircraft Acceleration Flight 

Data, and 

—Gravity Level Reports.

questions about the performance 

criteria, you may contact Randy Maday,
