DESCRIPTION
This nine-day course enables the engineer
to determine compliance with the
noise standards for aircraft type certification
as set forth in part 36 of the FAR.
OBJECTIVES
At the conclusion of the course, participants
will be able to:
- Explain the history of events leading to
the Noise Control Act of 1972, the
Aircraft Noise Type Certification
Programs, and equivalent findings.
- Explain the requirements for, and the
contents of, environmental impact
statements and negative declarations.
- Identify and explain the provisions,
application, and correct interpretation
of FAR 36.
- Explain the intent and meaning of
equivalent means of compliance procedures
as illustrated in Advisory Circular
36-4.
- Operate the various types of instrumentation
that may be used to measure
sound for noise certification testing,
and describe the functions, accuracy,
and operating procedures for each
instrument.
- List and explain the effect of the various
environmental factors that absorb
or attenuate sound and describe correction
procedures that may be used for
each factor.
- Describe the causes of fixed wing aircraft
and rotorcraft noise and explain
the effect of gross weight center of
gravity, flaps, poser, rate of climb and
airspeed on noise.
- Identify and explain the provisions,
application, and correct interpretation
of ICAO Annex 16, noting differences
from FAR 36 and emphasizing the specific
requirements for helicopter noise
certification.
- Explain the various methods used to
minimize noise in aircraft and engines
and describe procedures used to evaluate
the effectiveness of these methods.
- Evaluate test procedures and determine
from on-site inspection the adequacy of
test conditions, test sites, noise measurement
systems, meteorological measurement
systems and aircraft tracking systems.
- Evaluate example noise certification
data, analysis and correction procedures,
including computer outputs and
input algorithms, from a manufacturer
transport aircraft noise certification
program for compliance with FAR 36.
WHO SHOULD ATTEND
This course is recommended for all aircraft
certification engineers.
