FAR 36
Appendix G Small & Propeller-Driven Airplane Noise Measurements
 Beginning
in 2004, we have expanded our already extensive capabilities to
include small and propeller-driven airplane noise testing and
evaluation. A powerful combination. The
result? Combined with our aircraft performance, flight
characteristics, systems performance, instrumentation, and
real-time data acquisition capabilities, we now offer a
one-stop FAR 23 airplane flight test solution for your new,
modified, or special missions aircraft certification program.
Free
determination of acoustical change
Are you worried that the change
that you've made to your airplane might affect noise levels and
compromise certification?
Contact us for your FREE project noise level analysis.
In one hour or less, we can tell you whether or not noise
testing will be required. If your airplane has previously
certificated noise levels, we can tell you - with a high degree
of certainty - whether or not your modified airplane will exceed
the allowable noise levels. Regardless, we can always make
specific recommendations about how you can reduce perceived
noise levels and achieve airworthiness approval -- on time and
on cost.
To the Rescue
In 2003, we had a customer with
a highly successful seaplane product in Canada who had applied
for FAA approval in the United States. Seaplanes and
amphibians are exempt from demonstrating compliance with the
international ICAO noise requirements. But in the U.S.,
ALL airplanes must meet the FAR 36 noise requirements to get
airworthiness approval. The stakes were high -- with
hundreds of thousands of dollars on the line. One week
later, we had completed the noise testing and had FAA-approved
noise levels for his airplane!
We are now offering the following
services, supported by the same high quality customer support
and dedication we are well known for:
- Determination of
acoustical change
- Test planning and
management
- Reference flight profile
determination
- Instrument calibrations
-- traceable to NIST standards
- Calibrated and
certificated noise measuring equipment rental
- Noise level measurements
- Test witnessing
- Data analysis and
corrections
- Certification flight test
reporting
If you make a change to your
airplane that affects any of the following things, you are
probably required to demonstrate compliance with the noise
levels specified in FAR 36 Appendix G or ICAO Annex 16 Volume 1
Chapter 10:
- Increase takeoff distance
- Reduce climb gradient or
rate-of-climb
- Increase engine power or
thrust
- Larger diameter propeller
- Change maximum continuous
or maximum takeoff propeller RPM
Known for our friendly and
efficient flight test engineering support team, we are standing
ready to help you with any flight test services your project
requires. Contact us
today to find out how we can help you satisfy your small and
propeller-driven airplane acoustics needs.
